HON CHEMISTRY: Okay, for the record, water balloons do not obey Avogadro’s Law, but gas balloons do! Equal volume balloons contain the same number of molecules. And how about the Gay-Lussac’s Law of Combining Volumes? Yay, more great conversion factors!! How are you doing with blending the old and the new?

This week in Chemistry, I would rate myself a 4 out of 5 stars. The sprite can lab helped me to understand gas laws, and it showed how temperature affects the pressure of gas and the movement of its particles. It also helped me to form a visual picture to go along with Gay-Lussac’s Law. Now that I know all of the information from this chapter, I am going to study all of the formulas and laws so that I can work problems and make applications. I am enjoying this chapter because it helps to explain so many every-day occurrences involving gases– like the density of balloons filled with different airs and scuba diving!
This week I would rate myself a 4/5. I have been doing well on the homework problems and have even done my extra credit science in the news because of how well I have managed my time. I really enjoyed tying in the gas laws into stoichiometry problems because I loved that chapter. I will need to go back and study the names of each person responsible for each gas law but am looking forward to another good grade on the test on Monday.
This week I will rate myself 3/5. I have understood each new law well but when we mix them together on homework I get them mixed up. I think if I go to the help session and go back and learn the name of each law and it’s formula I will do better. I also enjoy this section because I am starting to see where the things we learned first semester are really beginning to apply to what we are learning now. I am looking forward to maybe doing the hot air balloon lab as well.
This week in Chemistry I give myself 4 out of 5 stars. I loved the Sprite can experiment because I had no I sea that was going to happen. I was so supprised when it crushed. It helped that we went and wrote why on a sheet of paper. I liked learning the ideal gas law. I felt like I was putting everything I’ve learned in this chapter together. I was supprised when we learned the gas stoichiometry. I feel like stoichiometry is everywhere. I did okay on the test that we got back. I was just upset that I made the careless mistake on the symbol for Mercury which cost me 6 points. I need to practice, practice these problems for our test on Monday. I also need to memorize, memorize all of the laws and people. I am hoping for a good grade on this test.
This week i would give myself a 4/5. a triumph for me this week was that i understood how to do the math part of the laws and understood them very well. now that i have learned how to do gas stoichometry it seems so much easier than it was on the test. a struggle for me was applying the math formulas to the names of whose law it was. my favorite part of the week was the Sprite activity. even though it gave me a mini heart attack it was cool to see how we made the can a vacuum for a second and saw how the air pressure crushed the can.
