5/9 Chemistry update and Homework due 5/16

Hi folks,

Last week we did a quick tour of the gas laws and spent time on a lab using the gas laws to determine the concentration of an acid. We will spend a bit more time on the math of the gas laws this week.

Homework for this week:

If you didn't finish the lab in class, please do the work at home.

GO OVER ALL OLD QUIZZES. I'd like to take the time to go over any issues or problems you may have in class this week. So, please, look over those old quizzes and come prepared with questions on concepts you may not fully understand. Don't feel shy about asking questions. Remember that whatever question you have, someone else may have but not even know that they have it. :) Any question on a quiz is fair game for the final, so look it all over carefully. If you want to email me the questions ahead of time, so that you don't need to ask them in class, that's fine too.

Good luck everyone!

Jim Mueller

Chemistry Final Exam on May 23

Hi folks,

Just a reminder that we have two more classes and then the final exam.

To prepare for the final, I would highly recommend taking a look at all your old quizzes. The final exam will be based on the same material those quizzes were based on. Be sure to go over all questions that you may have missed and be sure to understand them so that you'll be ready for the exam. If you have trouble understanding where you went wrong, there's a good chance the material was covered in a recording and you can also email me if you need help. Feel free to ask questions at the beginning or end of class as well.

I'll provide all formulas and constants so you will not need to worry about memorizing anything.

Good luck everyone!

4/25 Chemistry update and homework due 5/2

Hi folks,

Today we spent a bit more time with the concept of limiting reagents. The quizzes pointed out that there is still some issues with that concept. We then moved on to the concepts of concentration, molarity and dilution. Today's lab consisted of working with acids and bases, titration and molarity.

Homework for this week is to answer the questions on the enclosed .pdf as well as finish off the calculations for the lab we did in class.

Hit reset all

Change reaction to the 3^rd A+BC

Pump in some molecules of A and BC

What happens?

What happens to entropy?

Would this reaction take place spontaneously?

No Science Jim Chemistry Class This Week

Hi folks,

Just a reminder that there is no chemistry class this Friday due to Spring Break.

See you all next week!

4/4 Chemistry update and homework due 4/11

Hi folks,

Today we got into the confusing topic of entropy. The tendency for the universe to favor disorder over order.

For homework this week:

Read pgs. # 294 - 299
Do review questions #'s 34 to 38 on pg. 302
Do Exercises #'s 30-37 on pg. 304

3/18 Chemistry update and homework due 4/4

Hi folks,

Today we got into the concept of exothermic and endothermic reactions. Exothermic reactions are ones that release heat. Endothermic reactions are reactions that absorb heat. To see these reactions, we took several different substances and mixed them together to see if the temperature went up or down.

Homework due 4/4 is to:

Read the text book pages 288 - 293

Do Review Questions #'s 29 - 33 on page 302
Do Exercises #'s 28-30 on page 304
Do Problems #'s 5-7 on page 305

Chemistry Update 3/21

Hi folks,

Today we had an amazing fun lecture (irony) on oxidation-reduction reactions. This is a fairly tricky concept because there are so many things going on with these equations and the vocabulary is counter-intuitive.

Homework due 3/28

Read pgs. 337 - 357
Answer Review Questions #'s 1-5
Answer Exercises # 1 - 6
Also, do the 4 problems on the enclosed .pdf. Answers are enclosed as well but please…no peeking until you're done.

3/14 Chemistry Update and Homework Due 3/21

Hi folks,

This week we talked a bit about percentage yield, theoretical yield, actual yield, and what needs to be present in order to have molecules react with one another.

Homework for 3/21 is to:

Read 271 - 288 in the Conceptual Physics book
Do Review Questions #'s 17 - 28
Also, do the 2 questions on the enclosed .pdf.

Chemistry Class for 3/7

Hi folks,

Yesterday's chemistry class was a bit of a mess and I want to explain what happened there.

I lost power early Friday morning but assumed it would come back on quickly. Then I went to teach Friday Enrichment at 11 (which somehow had power) and got home around 12:30. At that point, I still didn't have power and neither did the clubhouse. However, it was too late to contact folks, especially since I did not have email. So, I showed up at the clubhouse with extra coats and blankets ready to hold class if folks could make it. At 1:40 only 3 folks had arrived so I cancelled class.

Sorry for any confusion and inconvenience that was caused yesterday. Let's hope that's the last of this weather nonsense!

2/28 Chemistry Update and Homework due 3/7

Hi Folks,

Today we did a lab were we used the reaction of baking soda and vinegar to inflate a balloon.  We changed the amount of baking soda that we used while we kept the amount of vinegar the same.  This allowed us to get a little more in touch with the concept of limiting reagents

.  

After looking at the quiz, it appears that some folks could use a bit more practice with limiting reagents.  So here are 4 questions to help you out with that need.  :)  I've included a .pdf of the answers as well.  These will be due next week.

For many of you, I also HIGHLY recommend going back and taking a look at naming ionic and covalent molecules.  Lots of you guys are still struggling with that.  Best way to do that is to grab some of those old quizzes and test yourself.    Your final grade will thank you.  

1.You combine 10.0 grams of hydrogen gas and 15.0 grams of oxygen gas. How many grams of water vapor are made? Which is the limiting reactant?

2H2 +O2 --> 2H2O

2. If 5.00 grams of copper metal react with a solution containing 20.0 grams of AgNO3, which reactant is limiting and what mass silver is produced? 

2AgNO3 + Cu -->2Ag + Cu(NO3)2

3. 20.0 grams of potassium hydroxide react with 15.0 grams of ammonium sulfate calculate the grams of potassium sulfate produced.

2KOH + (NH4)2SO4 -->  K2SO4 + 2NH4OH

4. In the reaction of chlorine and sodium to form sodium chloride, determine (1) the mass of sodium chloride produced and (b) the amount of excess reactant left if 30.0 grams of chlorine react with 30.0 grams of sodium

2Na + Cl2--> NaCl
