I've posted final grades. If I have not graded your OFA, I will do so and fix your grade later today. The OFA is due at noon today.
Thank you for a great year. You were a fantastic group of people. Except for this weird ending, this was a great year in chemistry! Thank you.

I forgot to give a deadline for the OFA. Deadline is Friday, 12:00 noon. If it gets here at 12:00:01, it will not be accepted. Please read the descriptions given Friday and Monday before making decisions on whether to do the final activity. Good luck with your finals!!!!! I'll post again before we go for the summer.

Grades are in Infinite Campus. Check your grade, read the below. Contact me with questions. If you choose to do the OFA, download the document, Find a good article FROM A GOOD SOURCE, Thoughtfully read. Fill out the document. Take a picture of your work. Attach it to the document in Google Classroom. Reminder: Only people with -8 or -9% can benefit from the final. -7% is iffy. (57 - 59%, 67 - 69%, 77 - 79%, 87 -89% might be able to raise their grades.) If you are happy with your grade or you can't raise it via the final, you do not have to do the Optional Final Activity.

After checking the Unit 8 Exam score and your overall grade in Chem after I drop your lowest test, decide if you want to do the Optional Final Activity (OFA). See below,
Instead of an exam, our final will be the Optional Final Activity (OFA). Do this activity if it will raise your letter grade. The only people who have a chance to raise their grade to the next higher level are people with -7% and above (eg, 77, 78, 79%). Scores in the -0 to -6 range (eg 80 - 86%) aren't close enough for the final to raise the letter grade. Those people should not do the OFA. In fact some could lower their grade with a poor OFA score. I will enter the Unit 8 Exam scores Monday morning then drop your lowest test score. This should be done by noon. At that point, you should decide whether or not to do the OFA. When your final grade is determined, then you need to decide if you want to choose Credit or your letter grade. I will give advice on that on my webpage. I'm running out of space here. Notice the due date on the OFA (Fri. 5/22 at 12 noon). It's hard and fast. No late OFAs accepted. A BIG COMPONENT OF THE GRADE ON THIS PROJECT IS THE QUALITY OF ARTICLE THAT IS ANALYZED. USE A RELIABLE SOURCE. EXAMPLES OF RELIABLE SOURCES INCLUDE, BUT ARE NOT LIMITED TO, SCIENTIFIC AMERICAN, SCIENCE NEWS, NATIONAL GEOGRAPHIC, DISCOVER, POPULAR SCIENCE, SCIENCE, SMITHSONIAN, COSMOS, ETC. The source MUST be scientific.
At some point, you will know your final grade in Chemistry. Some may know during finals week as they can't raise their grade with the OFA. Some will have to wait for the end of finals to know their final grade. Now you need to decide whether to take a Credit grade or the letter grade you have earned in class (the higher of the Midterm or Term Final grades for most of you). If I haven't contacted you about your situation, you will get the higher of the two grades. Please read the document attached below then decide what you want to do.

As I understand it, if your letter grade is lower than your GPA, you should take the Credit. If it raises your GPA, take the letter. This is all assuming that college admissions aren't impacted negatively by the CR vs the letter grade. As I understand it, colleges will not discount transcripts with CR. They know this is a weird time. Please read the above document and talk about this with your parents.

Watch tutorials then do HW 3 # 1 - 5.
Understand these tutorial videos and tackle HW 3 #1 - 5. Obviously this is stoichiometry, like the neutralization problems we did in HW 2 already. We actually did acid base stoich when we first introduced it last semester. You have done this before. Remember the 3 steps. 1. Get moles of your given 2. Use mol fraction from balanced equation to convert to moles of what you've been asked about. 3. Answer question, usually concentration of acid or base in M (mol/L). The reason this works on acid/base problems is that when an acid or a base is neutralized, by definition [H+] = [OH-]. You can use the concentration of either the acid [H+] or the base [OH-] to determine the concentration of the other. You do that using old fashioned stoichiometry. Simple.
I'd watch the last linked video first. It shows the technique of titration. Titration is a way of carefully adding measured amounts of a substance to a solution. You can neutralize the acid or base this way. You take the amount of known concentration acid, say, and use that to determine the concentration of the base that was neutralized. This is how the numbers that you have already calculated in neutralization reactions were generated. As always, I'm available via email or private chat in Google Classroom. Would love to hear from everybody.

Monday, May 4 - May the Fourth be with you.
I graded the quiz today. If you had problem with the Table in #6, review HW 1 part 3. If you work on those problems and communicate with me, I'll work with you to get some points back. Many will notice extra credit points. I felt like I under-presented some material and if you got that part of the data table correct, you got the points. It was the acid/base status. I felt like we didn't get much background on that. Reminder, if you are not understanding the tutorials or homework, please email me.
Keep plugging through this strange time. We will be fine with effort. Do the attendance. Do the work. You can do this.
Stay tuned for more new material tomorrow. Acid-base neutralization calculations.👍

Holy cow. Operator error all over the place. I just now posted the Unit 8 Lab as an assignment in Google Classroom. Take a pic of your work and turn it in there like the last lab. The lab document is in the document section on the website.
And how about putting my Wed communications into the Thursday description? I need a vacation from quarantine. Thanks for those of you who endured and come to the chat.

It's working now. 11;47 Clink the link through the invite I sent. Definitely my error. If you don't get an invite, zip me an email. I left the room open longer so we will go to 12:30 today. I know how to do it now and it will work better next time. Thank you for your patience.
Right now the links aren't working. Give me a second and I'll stumble around and hopefully find something to fix it. It's 10:11.
Let's do a GoogleChat from 10 - 12 today. This is not an assignment but an opportunity to ask questions or just interact a little. I ask you to remember all the expectations regarding a huge chat room. Appropriate, content focused, etc. This is new to me so be patient. Use the link within Google Classroom. Here's the link in case that doesn't work. However, I think they get all weird with you if you don't go through Classroom. If it works this way, I'll be surprised. - https://chat.google.com/u/1/room/AAAA-ijiaBM
I'm also assigning a lab. Complete the Unit 8 Lab in the documents section by end of day Thursday. Open note quiz Friday over HW 1 and 4.

Hi gang. I added a reading today. This is a background reading, one that may support the tutorials you looked at last week. This may put together any scattered understandings. It won't help on the calculations but will with more general acid base concepts. If you have any questions or just want to chat, please email.
As a group, you've been doing well with the attendance and well overall frankly. Keep it up!
Keep your eyes out for a google chat tomorrow. (this is so exciting!)

Mr. Broer wanted us to make this known again. This is the message you received earlier from him.
Jeffco Policy: The grade a student earned as of the grading period concluding prior to March 13, 2020 (the day before our first week of remote learning), will serve as the lowest possible grade a student can receive for this semester as long as students continue to participate. For Chatfield, we have called this Mid-Term grade and is currently posted in Infinite Campus.
Additionally, students can move their grade to a credit/no credit indicator on the transcript.
Seniors let me know before May 1. All others by June 5th, if you are choosing Credit/NoCredit.
For this semester, all F grades will be transcribed as “no credit."
Please let me know ASAP if you will be doing something OTHER THAN a letter grade (ie you are doing the credit/no credit option).

Understand that as long as you give an effort (like in the document sent to you all by Mr. Broer) you can't do worse than your grade as of 3/13. You can only raise the grade. Relax. Do your best. This can only help you (as long as you participate as in Mr. Broer's email). Why not give a real try?

I've returned the labs. If you turned it in, you got full credit (20/20). Lab grades are entered into Campus. As always, if there are any issues regarding the lab, grading or what went into the gradebook, email with questions. There will be questions from the lab on the test Friday.
Test will be Friday. Not sure the exact format yet but it will be like our usual exams with multiple choice questions. It will be a little shorter (20-25 questions) and will be open note. And much more so than usual, you will be on your honor regarding communicating with others (cheating) during the exam.

Complete the review. The review has a couple of problems/definitions that we didn't get a chance to talk about. Do your best on those problems. Look them up. The test will not cover those areas. (Problem section #10, 11) The review is also light on solution stoichiometry. I am producing a short assignment reviewing solution stoich. It, and an answer key, will be on the Chem Documents page this afternoon.

Finish the lab, if you haven't already. Take a picture and attach it to what you turn in on Google Classroom. Attach to an email directly to me only if the Google Classroom thing doesn't work. You can start the review today. I'm not getting many emails. I hope you all are good with the Unit 7 content and are good overall. I miss you all. I have nobody to frustrate in person. My wife doesn't count. She's constantly frustrated with me, quarantine or no. Take care and communicate.

Download the lab document (chem_7_conc_molarity_phet_act.pdf), go to the suggested website and follow the directions. Complete suggested activities and take a picture of your written product. Attach that to the assignment you turn in to Google Classroom, like we did with the quiz. Ask questions via email or Google Classroom. It's a good solutions activity and a break from endless problem solving. There are problems in here, though. Imagine that. A chemistry assignment with calculations. This is due by the end of the day Thursday.
I haven't had many content questions since we went to whatever we call this style of teaching/learning. We're going pretty slow. The content is pretty straight forward. You are smart and hard working. It is possible you all are on top of this stuff. It is also possible that some of you are hoping that this will all go away without a grade or anything attached to it. We have to teach. We have to do as much as we can given the circumstances. We have to enter grades for you all. You should participate actively in the process. You will understand this stuff if you try. I will help. You will ask questions. I will help. Please include me on questions regarding anything that's going on. I want to help.
Tentative Unit 7 Exam date = Wednesday, 4/15. We'll probably start reviewing Friday.

Tuesday - I'm grading the quizzes today. The numbers listed in the comments/message section are the numbers missed.
It's Monday, about 5:00 pm, still time to turn in the quiz. I'll grade it Tuesday and get the scores online asap after that.
I'm getting almost no emails asking for content help. Hopefully that's a good sign but......
Tuesday, get after this assignment. Finish HW 5. Ask questions. Or not. I'm here to help. I hope you all are doing well and are comfortable. I'll probably add to this post tomorrow.

Sorry for the delay today. I didn't get active until later and my other class, AP Bio, blew up with new information that had to go out quickly.
The two tutorials on solution stoichiometry are pretty good. Watch, actively listen, learn;-). My hints are pretty general at this point. Here we go.
Links to solution stoichiometry tutorials -https://www.youtube.com/watch?v=rPND65LPwS0
-https://www.youtube.com/watch?v=EKZSwjVR594
Like every stoichiometry problem, you know it's stoichiometry if you have been given information about one participant in a reaction and want to know something about another participant in the reaction. (You could have information about a reactant and want to know about a product or reactant. Or you could have information about a product and asked about a product or reactant. It doesn't matter where you are in a reaction regarding given or unknown.)
Once you determine you'll have to do stoich, write and balance the equation. Be methodical. Any mistakes you make in formula writing, equation writing and equation balancing will ruin any subsequent work. After a carefully written and balanced equation is completed you:
- 1. Get moles - if you are given moles, this job is already done
- We've done that using molar masses when you are given mass (you must remember how to do that using molar masses from the PT)
- We've done that using the Ideal Gas Law (you must remember how to do that, using the ideal gas law to calculate n in the equation)
- In solutions, moles are calculated from molarity concentration values - Like in problem #9 in HW 5 - see answer key for help- it's pretty intuitive. Do what it takes (with molarity (M) being mol/L) and the given volume (in L) to generate a mol value as your final unit.
- 2. After you have mols of the given molecule, use the balanced equation to get the mol fraction to convert to mols of the pertinant molecule. Use it to convert to mols of what you were given to mols of what you want to know about.
- Mols of what you want as the numerator of the mol fraction, mols of what you were given as the demonimator. These mol values come from the equation. Have I said that enough? I'm not going to run through an example here. We've been using mol fractions (mol ratios) for a while. You have resources in your notes and old homework assignments to access to review, if needed. Of course I'll help, but you have some control here.
- 3. Do what it takes to answer the question. Sometimes it will ask for a mass. Use mols calculated in 2. and molar mass to answer the question. Sometimes it will ask for a concentration, usually molarity M ( also called molar concentration) in which case you will use the mols calculated in 2. and the volume given in the problem to solve the problem. Again, this is review from earlier. In this case, from this unit's homework assignments.
- It's okay to use the key to see it once to remind yourself. If you use the key more often, you're not really doing the work yourself. You've done this off and on since November. You can do it. Email or contact me via Google Classroom.
- It's a fairly long assignment and is due Tuesday at the end of the day. It's homework and we'll deal with grading it before we take the exam. Unit 7 Exam will probably be next Friday.
Reminder - Mondays are days where no assignments are given.

We are good to go on the assignment below. I think.
As I've had very few questions, I'm feeling like it's time to take a look at what we (i.e. you) understand. I think I've assigned a quiz-like thing on Google Classroom. It will just be an assignment there, not a quiz. I'll grade it and put it in the quiz section on Campus. You can use your notes/homework on the quiz. You are on your honor regarding other help. The stated deadline is Friday, 3:00. I'll take it until end-of-day Monday. We'll move on to solution stoichiometry tomorrow.
I hope you all are doing well. It will be at least another month before things start creeping back to normal. Another month of this. Do your best. Communicate with me. Realize we are in this together, both as teacher/student and as citizen/citizen.

Check out the tutorial videos. Writing a double replacement reaction should be easy. All these reactions are happening in water. The new thing is how do you know if an ionic compound is soluble in water or not. It can be answered using the back of your periodic table. The bottom left corner has a chart Table of Solubilities of Some Ionic Compounds in Water. I can't figure out how to paste the dang table in here. Use yours and follow along.
What you do in this situation is to: 1. watch the tutorials 2. do the double replacement reaction as described. 3. Check each of the product molecules to see if they are soluble in water or not. If the compound is soluble, it will remain dissolved, in ionic forms. If the molecule is not soluble, it will precipitate in solution. Mark the solid compound with (s) because it doesn't stay dissolved. Mark the ions with (aq) because they stay dissolved in water (aqueous). An example is below.
From our HW 4 #2 - last (third) video is of hydrochloric acid and lead(II) nitrate being put together. The cloudy substance forming is a precipitate, a solid, It precipitates out of solution like rain or snow precipitate from the gaseous solution that is our atmosphere. The equation for the double replacement reaction when hydrochloric acid is added to lead(II) nitrate is:
2HCl(aq) + Pb(NO3)2(aq) --> 2HNO3 + PbCl2
- the reactions happen in water so the reactants are denoted (aq), meaning dissolved in water.
-to figure out the products, I check the above mentioned table for the solubility of HNO3 first. The first two rows of the chart don't apply to this reaction, but the third row does. It says that NO3- ions are soluble when bonded with any positive ion. So they stay dissolved. So the HNO3 is not the precipitate. It must be the PbCl2. Let's verify. The 5th line down is dealing with some halogens. Notice that lead halogens are not soluble. See the Pb+2 listed on the top line of the row? See that it forms insoluble compounds (it's not soluble)? This means that the molecules precipitate out of solution. The lead(II) chloride is the cloudy precipitate in the video.
The total ionic equation would read:
2HCl(aq) + Pb(NO3)2(aq) --> 2H+(aq) + 2NO3-(aq + PbCl2(s)
The net ionic equation just includes the ions from the reactants that formed the insoluble product. In this case:
2Cl-(aq) + Pb2+(aq) ---> PbCl2(s)
A note on the reactants and (aq) - by writing 2HCl(aq), we are saying that the HCl is dissolved into 2H+ and 2Cl- ions in the water, we're just not separating them for simplicity/brevity's sake. Same for the Pb(NO3)2 (aq) being Pb+2(aq) and 2NO3-(aq).

We need to be up to speed on the material in Homework 1 - 3. I'm expecting these videos will help. They are different than the original tutorials and may have that one perspective that smooths out all the rough spots. I'm worried. I haven't gotten many emails. I hope you understand the material. If you need help, let me know. We'll start in on Homework 4 tomorrow. I will definitely grade the homework. Still not sure what to do about quizzes/tests/labs. Suffice it to say, we need an evaluation or two. Stay tuned.

Monday, March 30.
I'll post our activities on the calendar. Go to google and do the attendance. Also, I'll put in the grades on the reading quiz we took the week before the week before spring break (last week). I haven't decided how I'm going to evaluate you yet. Keep doing the assigned homework. I'll grade that for sure. Email with questions.

What I've done is to put the whole week's worth of work on the calendar, broken up kind of like we might do in class. Monday, today, is not a contact day. The work needs to be done by Friday. Do it how you see fit.
Until I can figure out how to access my files from home, the ANSWER KEYS FOR U7 HW2 and HW3 are SWITCHED. The key for HW 2 should be used with HW 3 and the key for HW 3 should be used with HW 2. Hope everybody gets this. Spread the word.
Don't stress on this. Do what you can. I think you can do this work. If not, email me with questions. Regardless, take care of yourselves.
Is it a good thing or a bad thing to live in interesting times? Here we are.

Welcome back! I hope you had a fantastic summer and are ready for a great class. Chemistry is a course that covers the science of what everything is made from and how these materials interact. We’ll be learning about the substance of everything in the universe. We’ll be busy. What follows is some information on how things will work in here.
GRADINGYour grade in here is based on the following items:
Tests 30%
Quizzes 20%
Final exam 20%
Lab work 20%
Homework 10%
At the end of the semester, grades will be calculated on a percentage basis using the scale of 90 – 100% = A, 80 – 89% = B, 70 – 79% = C, 60 – 69% = D and less than 60% does not meet the Chemistry standard.
ATTENDANCEAn important aspect of any class is you being there, on time. School attendance policies regarding absences will be followed. After any absence, it is your responsibility to obtain assignments completed on the day missed. This can be done by checking the calendar on the website. Students are expected to use the restroom during passing periods.
SAFETYAnother important aspect of a Chemistry class is being safe in here. There will be many opportunities for labs that have hazardous chemicals or fragile equipment involved. During all labs, proper safety procedures will be followed. These procedures are described in the safety contract you will sign.
MISCELLANEOUS-Labs must be made up within a week of the completion of the lab. We’ll put the equipment away after that, eliminating your opportunity to make up the lab. Even if you miss the lab, you’ll be responsible for understanding the content.
-Quizzes will be taken regularly.
-Homework is a learning tool. Getting it correct the first time is not the goal, understanding the material is. You will grade your own homework. On the day before each exam, a homework grade will be given based on the completeness of your work, not the correctness. In addition, there will be Daily Maintenance checks of completeness of homework. These will happen randomly and are designed to reward keeping up with the pace of the course. If you are doing the homework but not understanding the content, it is your responsibility to change that.
-Every day you will need your Chem notebook, paper, pencil, periodic table and calculator. On certain days, you’ll need your textbook and I’ll try to give advance notice.
-Cell phones may be used only when explicitly stated, certainly not during lecture or labs. I’ll take the violating equipment away for the day.
-Show respect for all people and property in this room.
HINTS: Communicate with others about what is going on in here. Science is a social undertaking. You understand better if you talk with someone.
If you are having trouble with anything, talk with me. It is the best part of my job and could help you.
Try your hardest. This means working on a daily basis. Our course is one that the content accumulates over time. What you learn tomorrow will be built on your understanding of today’s work. Don’t get behind.
This is a college prep course. You will have more responsibility and more freedom than in other courses. See the description of Homework above, as one example. Another example is note taking. You will be expected to take notes and to use those notes as a reference tool. If you’ve taken notes and tried to use them to help you (i.e. shown responsibility for your learning), but still don’t understand, any teacher on the planet would help you. If not………
Monitor your own learning. A person’s understanding of his or her learning is called metacognition, and everybody learns differently. Figure out what works for you.
Take pride in all aspects of your work, including presentation. You won’t get credit for work I can’t read.
Show your work. One of the goals of the class is to develop problem-solving skills. You’ll need to communicate these skills in writing. With your work showing, I may be able to see where you made a mistake and award partial credit. If no work is showing…….
Have fun. Success makes people happy. If you stay on top of things, this can be a fantastically rewarding class.

Try your hardest. This means working on a daily basis. Our course is one that the content accumulates over time. What you learn tomorrow will be built on your understanding of today’s work. Don’t get behind.
This is a college prep course. You will have more responsibility and more freedom than in other courses. See the description of Homework above, as one example. Another example is note taking. You will be expected to take notes and to use those notes as a reference tool. If you’ve taken notes and tried to use them to help you (i.e. shown responsibility for your learning), but still don’t understand, any teacher on the planet would help you. If not………
Monitor your own learning. A person’s understanding of his or her learning is called metacognition, and everybody learns differently. Figure out what works for you.
Take pride in all aspects of your work, including presentation. You won’t get credit for work I can’t read.
Show your work. One of the goals of the class is to develop problem-solving skills. You’ll need to communicate these skills in writing. With your work showing, I may be able to see where you made a mistake and award partial credit. If no work is showing…….
Have fun. Success makes people happy. If you stay on top of things, this can be a fantastically rewarding class.
