1. Which of the following gases could have the same pressure and temperature? All of the containers are rigid and have the same volume.

A.Ne and N2

B.O3 and H2O

C.N2 and O3

D. Ne, N2, and H2O

2. The decomposition of sodium azide (NaN3) is often used to inflate car airbags. A possible balanced chemical reaction for this decomposition reaction is 6 NaN3(s)+ 2 Fe2O3(s) = 3 Na2O2(s) + 4 Fe(s)+ 9 N2 (g). What volume of nitrogen can be produced at 20.0 °C and 1.05 atm from 1.00 mol of NaN3?

3.. The density of the vapor of a volatile organic compound is 0.960 g/L at 0.2434 atm and 225°C. What is the molar mass of this compound?

4. A gas mixture contains 0.0500 moles of H2, 0.0400 moles of CO2, and 0.0325 moles of N2in a 2.00 L flask. If the total pressure in the flask is 1.316 atm, what is the partial pressure of CO2?
