HON CHEMISTRY: Here’s our look at the gas laws today: Boyle’s law, Charles Law, Gay-Lussac’s law, and the combined gas law. Thank you, Millie, for being “guest writer” today! These gas law guys did great work – and you’ve got to love their hair!! Can you apply what they discovered in everyday situations?
Be sure you use Kelvin in the problems – not Celcius. And make double dog sure you use the formulas correctly! Rearrange that thing – no plug and play!! Here are answers from tonight’s homework:
20.) 121 K or -152°C
21.)142 mL
22.) 0.360 atm
23.) 3.41 L
24.) 127°C
25.) 38.8 kPa
32.) -43°C
33.) 9.98 m3/day
60.) 2.18 L

This week in Chemistry, we are continuing our study in gases. We have learned lots about how pressure, temperature, and volume are all related, and about the people who found the laws. We have also learned about how moles of gases and liters are related and can be used in stoichiometry. I am doing good on the math part of it, but just having some trouble with remembering all of the formulas and people. Will study hard over the weekend for our test early next week!
