THESE ARE THE PROBLEMS THAT I AM STUCK ON. ANY IDEAS ON HOW TO DO ANY OF THEM? GREATLY APPRECIATED 
1. A student in lab has 5.00 g of pure N2 in 0.901 g pure H2. The reaction happens following this equation:
N2(g) + 3H2(g) → 2NH3(g)
How many grams of NH3 would be produced?
2. Methanol can be made by the direct reaction of carbon monoxide and hydrogen gas, by the following equation. CO(g) +2H2(g) --> CH3OH(l) If 11.40 grams of hydrogen gas are mixed with 230.00 grams of carbon monoxide, how much of the excess reactant, in grams, remains?
3. If you have the following balanced equation which shows the reduction of copper from copper oxide, what is the number of grams of Cu that can be obtained if you have 574 grams of copper(II) oxide and 29.0 grams of hydrogen?
H2(g) + CuO(s) → Cu(s) + H2O(g)
4. Disulfur dichloride, S2Cl2, can be made by treating molten sulfur with chlorine gas, according to the following unbalanced equation:
S8(l) + Cl2(g) → S2Cl2(g)
How much S2Cl2 (in grams) can be produced if you start with 24.45 grams of sulfur, and 88.27 grams of chlorine gas?
5. You have equipment that operates at 88.0% efficiency for the reaction below.
Fe2O3(s) + 3CO(g) → 2Fe(s) + 3CO2(g)
If you need to produce 49.2 grams of iron in your equipment, how many grams of iron(III) oxide must you react with excess carbon monoxide?
