The combustion of acetylene gas is represented by the following chemical equation: 2C2H2(g) + 5O2(g) ---> 4CO2(g) + 2H20(g)

1. How many liters of CO2 are produced when 5.20 L of C2H2 burn in oxygen?

2. How many liters of oxygen are required to burn 3.50 L of acetylene?

P4O10 > 4P + 5O2

3. How many moles of phosphorus would be produced if 2.5 mol of P4O10 reacted?

4. How many grams of oxygen would be produced if 1.6 mol P4O10 reacted?

4 Al + 3O2 > 2Al2O3

5. How many moles of Al are needed to form 2.3 grams of Al2O3?

Ammonia and oxygen react to form nitrogen monoxide and water, like this: 4nh3 (g) + 5o2 (g) → 4no (g) + 6h2o (g) also, a chemist finds that at a certain temperature the equilibrium mixture of ammonia, oxygen, nitrogen monoxide, and water has the following composition: compound pressure at equilibrium nh3 65.1atm o2 31.3atm no 62.7atm h2o 65.8atm compound pressure at equilibrium nh3 65.3 atm o2 7.79 atm no 12.1 atm h2o 65.8 atm calculate the value of the equilibrium constant kp for this reaction. round your answer to 2 significant
