1. Ammonia is produced by the reaction of hydrogen and nitrogen.
N2(g)+3H2(g)→2NH3(g)ammonia

How many moles of N2 reacted if 0.65mole NH3 is produced?

How many moles of NH3 are produced when 1.2moles H2 reacts?

2.In the acetylene torch, acetylene gas (C2H2) burns in oxygen to produce carbon dioxide and water.
2C2H2(g)+5O2(g)→4CO2(g)+2H2O(g)

How many moles of O2 are needed to react with 2.10moles C2H2?

How many moles of CO2 are produced when 4.0moles C2H2 reacts?

How many moles of C2H2 are required to produce 0.50mole H2O?

How many moles of CO2 are produced from 0.100mole O2?

I thought I did #1 last night. All of the others are off shoots of that. Remember that any component in an equation (in mols) can be converted to any other component in the reaction by using the coefficients in the balanced equation.
yes
