AP Chemistry Summer Assignment
2016-2017
Welcome to AP Chemistry. It is my hope that you will be successful this year. One way to
ensure this is true is to have a good grasp on the basics before we begin. The following
assignment is designed as a review of the important concepts learned in your first year of
chemistry.
AP Chemistry is a difficult course and will require a significant amount of time preparing. More
than just memorizing information and patterns, you will need to understand the concepts and
apply them to many different situations.
This assignment will be due the first day of class. There will be a test on the second day over all
of the review material. The NMSI website has helpful videos and notes to help you review, the
notes from the website will serve as our review of those sections. The notes are fair game for the
test, so make sure you have downloaded them. The password for the video section is:

Thanks and have a Great Break!!!

a. NO
b. NO2
c. N2O4
d. N2O
2. Benzene contains only carbon and hydrogen and has a molar mass of 78.1 g/mol. Analysis
shows the compound to be 7.44% hydrogen by mass. Find the empirical and molecular
formula of benzene.
3. Calcium carbonate decomposes upon heating, producing calcium oxide and carbon dioxide.
a. Write a balanced chemical equation for this reaction.
b. How many grams of calcium oxide will be produced after 12.25 grams of calcium
carbonate are completely decomposed?
c. What volume of carbon dioxide gas is produced from 12.25 grams of calcium
carbonate at STP?

temperature is 30.0°C? (R=62.4mmHg-L/K-mol)
4. Hydrogen gas and bromine gas react to form hydrogen bromide gas.
a. Write a balanced equation for this reaction.
b. 3.2 grams of hydrogen reacts with 9.5 grams of bromine. Which is the limiting
reactant?
c. How many grams of hydrogen bromide gas can be produced using the amounts in (b)?
d. How many grams of excess reactant are left unreacted?
