Science Through the Eyes of a Wolverine

Click on this site to practice empirical formulas problems before the retake. Remember to try 9-12.

Answers…

9…C5H7N is emp, C10H14N2 is molecular

10…HgC2H3O2 is emp, Hg2C4H6O4 is molecular

11..SrSO4 is the emp and molecular

12…C21H22N2O2 is the emp and molecular

Remember we are having a review day for naming compounds and writing chemical equaitons on Monday, November 16th. On Tuesday, November 17th, we will be having a review over mole conversions, percent composition and empirical formulas. YOU MUST BE AT ONE OF THESE SESSIONS IN ORDER TO RETAKE A QUEST.

We are starting stoichiometry notes with a cool lab by the end of next week maybe. Read the packet I gave you to be ready for class on Monday.

Honors Chemistry…this is your HW questions…

Write the formulas for:

silver chloride

potassium nitrate

magnesium oxide

lead (II) nitrite

gold (I) hydroxide

ammonium sulfate

oxygen difluoride

carbon tetrabromide

General Chemistry make note cards for the following polyatomic ions:

ammonium, acetate, carbonate, chlorate, chlorite, dichromate, hydrogen carbonate, hydrogen sulfate, hydroxide, chromate

This week in AP Chem will be a continuation of last week’s learning about the nucleus of the atom and why it splits.
The problem set will be due on Wednesday and Review Day will be on Thursday. This will set us up for our 2nd Quest on Friday.

In Physics this week, we will begin moving from linear motion to non-linear or projectile motion. This is found in CH 3. A variety of problems will be done throughout the week in class and we will be performing a few activities outside “throwing” projectiles. By the end of the week we will be in the lab working on our projectile tossing apparatus. Our second Quest will be done sometime next week.

In Honors Chem we will build upon our knowledge of chemistry by understanding matter and the way it can be changed. The periodic table will be a focus for us as well.

General Chemistry will focus on Matter and we will be completing Reviews 1-4 throughout the week. A lab is scheduled for mid to end of the week and our next quest will be early next week or the end of this week.

Here are the notes for the lab…have them copied down before class on Tuesday… AP Chem Lab Book

OK, I am giving you a week off as far as a “God Question” goes, but be prepared for a doozy next week. Some of you have made comments about “Why are we talking about God in chemistry class?” and “Why do you care what we think about God?” Here is my response…”Why wouldn’t I want to listen to what you have to say about God?” I realize that this is not “RELIGION” class but does God live outside religion class or outside church? We should not have a problem sharing our thoughts about God in any atomosphere. Think of it this way…”If we only talked about God in church or Religion class, how would anyone else ever hear about God and how great He is? So, be prepared to have more discussions about God in Chemistry class. Maybe this trend will pass to history class, math class, english class, etc.

Enough soap box time for me…on to this week’s question.

Explain in a minimum of 2, 5 sentence paragraphs the pros and cons to high electricity and high transportation usage of the average American. Could we live without using so much energy? How would life be different if we used less like solar power, wind power, geothermal energy, electric cars instead of gas and much more. Explain the convenience factor. Could Americans upset their lives of convenience for the preservation of our air quality? Does it matter?

As usual, there a quite a few questions. The goal is not for you to specifically answer each question, but they are given so that you have some direction in writing your response. I want you to think carefully about the questions and respond accordingly.

YOU WILL RECEIVE NO CREDIT THIS WEEK IF I DO NOT SEE TWO PARAGRAPHS WITH A MINIMUM OF FIVE SENTENCES EACH. I usually do not look for long drawn out answers, but some of you need to put a bit more thought into your answers, so we will start with 2 paragraphs and 5 sentences. It may increase from here.

Question 2: H2 was collected by water displacement from the reaction of 0.45g of zinc in excess nitric acid at 24C and an atmospheric pressure of 700mmHg. What is the molar volume of H2 gas produced according to this experiment? I need a summary of the math here.

OK, this was not going to be the question for this week, but after reading all the responses, I think it is a necessary progression.

Our good buddy James says that faith without works is dead. But Paul writes a letter to the church in Ephesus that seems to oppose this view–or does it?

Here is what Paul has to say…

8 For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, 9 not a result of works, so that no one may boast.

So, what of it? Are Peter and James in disagreement on this issue? Is James saying that we need to do good works in order to reach Heaven? Is Paul saying that being saved has nothing to do with our works? What is going on here?

To get credit this week, you need to discuss what grace, faith and works have to do with one another and synthesize James and Paul or explain why they are contrdicting each other. Can the Word of God contradict itself???

I do not have a tie in question that relates grace and works to pollution or global warming, sorry.

Question #2

How much faster will Hydrogen gas diffuse throughout a room than Xenon gas?

Yes, the brochure is still due tomorrow when you get to class.

You will not have time to work on it in class. This assignment was given as a way to help your grades out and give you an EZPZ way to get a 100% on a quest.

If you do not turn it in…you will receive a zero on a HW grade.

There will be no late brochures accepted for any reason. Sorry
