I am posting photos I took of the gas packet, in case you are missing yours. I will also post answers to the problems later this weekend, as well as extra gas practice problems later this weekend

Before class on Tues., Jan 3
Before class on Tuesday, Jan. 3:
- Please watch the 8 videos below (in total 90 min). These videos follow the notes I handed out in class;
- Complete the multiple choice and free response questions in the gas packet I handed out to you.
If you have questions on this material, please email me at suzanne.irwin@lcps.org or send me a remind text. We will be practicing gas problems and discussiong how the structure of molecules affects the properties of solids, liquids, solutions and gases on our first day back. We will start our next unit, on Kinetics, on Jan. 5 . You will have a unit test/quiz on Solids, Liquids, Solutions, Gases and their properties on Monday, Jan. 9.

Review for Unit 3 Test
Our Unit 3 Test will be on how we find out how much of a substance we have: using moles, or percent composition. It will also include questions on ionic bonding and naming and writing formulas for ionic compounds. Here is the blank study guide. I recommend that you complete the study guide and make sure you know how to do the problems for each learning target. I will post the answers on Sunday, Dec. 4.
