A 2.0 L container is filled with N2 gas at 1 atm and 25 °C is connected by a closed valve to a 3.0 L container filled with O2 gas at 2 atm and 25 °C. When the valve is opened, what is the partial pressure of the N2 gas after mixing? Given P1V1 = P2V2 and the Ideal gas constant, R = 0.08206 L-atm/mol-K.

Calcium carbonate, CaCO3(s), the principal compound in limestone, decomposes upon heating to CaO(s) and CO2(g). A sample of CaCO3 is decomposed, and the carbon dioxide is collected in a 2.50 L flask. After decomposition is complete, the gas has a pressure of 1.3 atm at a temperature of 31 °C. How many moles of CO2 gas were generated? Given the ideal gas law PV = nRT and the Ideal gas constant, R = 0.08206 L-atm/mol-K.
