N2(g) + 3H2(g) → 2NH3(g) 8.99 L of N2(g) is mixed with 7.64 L of H2(g) and reacts with 100% yield. What volume of NH3(g) is produced? Assume all gases are at the same temperature and pressure.

Titanium(III) chloride is used in the manufacture of polyethylene. It is produced by the reaction (at high temperatures) between TiCl4 gas and H2. 2TiCl4(g)+H2(g)2TiCl3(s)+2HCl(g)Assume 100% yield and constant temperature and pressure. (a) How many liters of HCI gas can be produced by mixing 3.72 L of TiCl4 and 4.50 L of H2? (b) How many liters of reactant in excess are present after the reaction is complete?

Potassium peroxide is used to absorb the CO2 produced by the people in a space vehicle. 2K2O2(s)+2CO2(g)2K2CO3(s)+O2(g)If a person at rest exhales 3.0 L of air per minute and CO2 is 3.4% (by volume) of exhaled air, how many grams of K2O2 are needed per person for a five-day trip. Assume a temperature of 250 and 728 mm Hg pressure.

You have a gas, one of the three known phosphorus-fluorine compounds (PF3, PF3, and P2F4). To find out which, you have decided to measure its molar mass. (a) First, yon determine that the density of the gas is 5.60 g/L at a pressure of 0.971 atm and a temperature of 18.2 C. Calculate the molar mass and identify the compound. (b) To check the results from part (a), you decide to measure the molar mass based on the relative rales of effusion of the unknown gas and CO2. You find that CO2 effuses at a rate of 0.050 mol/min, whereas the unknown phosphorus fluoride effuses at a rate of 0.028 mol/min. Calculate the molar mass of the unknown gas based on these results.
