4/1/2020 Distance Learning Day 1: Stoichiometry, Limiting Reactant, and Percent Yield Review
I am posting the powerpoint that I went over yesterday. When I looked at my video that I recorded today I sounded like Jabba the Hut talking over my presentation. I will rerecord over the presentation and will have it posted over the weekend.
We had a review of Stoichiometry, Limiting Reactant, and Percent Yield. I am also posting a few videos that review over the steps for how to set-up problems for each of the different instances.

4/3/2020 Distance Learning Day 2: Gas Variable Relationships
Today we did checkpoint 1 for the Gas Laws project. This checkpoint consists of 3 videos in which we are change either pressure, temperature, or volume of a gas and one of the other variables is also changing. I am adding the 3 videos below along with the 2 variables that are changing. In checkpoint 1 please finish filling out the data table and answering the questions at the bottom. We will discuss any questions on this checkpoint on Tuesday and will be moving into the math that goes with these relationships.

4/7/2020 Distance Learning Day 3: Gas Law Equations (Boyle's, Charles', Guy-Lussac's and Combined)
Today we discussed the relationships that we have talked about for Checkpoint 1. We also put mathematical equations to each of the relationships. I am attaching the PowerPoint for the entire unit of gas laws below. I will also post a video going over examples of each law.
Things to remember for gas laws:

Things to remember for gas laws:
- Your temperature must always be in kelvin. To change from celsius to kelvin the equation is Kelvin = Celsius +237.
- STP means standard pressure and temperature. Temperature at STP is always 273 K. Pressure for STP depends on your unit and can be any of the following: 1 atm, 760 torr, 760 mmHg, 101.3 kPa, 29.92 inHg.
- For any of the above gas laws your first and second units for pressure and volume must be the same. Example: if you start with 34 mL your second volume but also be in mL.
