In your Do Now today (2/9), you had to answer the following questions:
1. What happens if you decrease the size of a container that a gas is in?
2. What happens if you increase the size of a container that a gas is in?
3. What happens to a gas if you heat it up?
4. What happens to a gas if you cool it down?
Now, your task will be to create a visual (using map colors, markers, etc) to demonstrate
you. Turn them into this drop box.

C7H6O3 + C4H6O3--->C9H8O4 + HC2H3O2
To determine the percent yield, we need to first determine the theoretical yield if the reaction were to proceed completely. Then, we divide the actual yield that is given to the theoretical yield times 100 percent. The limiting reactant from the reaction would be salicylic acid. We do as follows:
Theoretical yield: 50.05 g C7H6O3 ( 1 mol / 138.21 g ) ( 1 mol C9H8O4 / 1 mol C7H6O3 ) ( 180.157 g / mol ) = 65.24 g C9H8O4 should be produced
Percent yield = 55.45 / 65.24 x 100 = 84.99%
Therefore, the percent yield for the given amount of salicylic acid is 84.99%
