Gas Stoichiometry

Q. Calcium carbide,CaC2, reacts with water to produce acetylene gas(ethane), C2H2, and solid calcium hydroxide. The ethane gas is collected over water at a temperature of 32C and a barometric pressure of 106.5kpa. What volume of acetylene, in ml, would be produced from 2,49 g of calcium carbide? What volume would this gas occupy at STP?

Gas Stoichiometry

Q. Nitrogen monoxide is a pollutant commonly found in smokestack emissions. One way to remove it is to react it with ammonia. 4NH3(g) + 6NO(g) → 5N2(g) + 6H2O(ℓ) How many liters of ammonia are required to change 36.4 L of nitrogen monoxide to nitrogen gas? Assume 100% yield and that all gases are measured at the same temperature and pressure.
