Nitrogen gas and hydrogen gas are combined in a reaction to produce ammonia. If 6.0 moles of N2 and 6.0 moles of H2 are present in the mixture, which is the limiting reactant?
Show work
The hydrogen gas will act as a limiting reagent, i.e. it will limit the amount of nitrogen that takes part in the reaction.

Analytical Chemistry Calculate the molarity of a 30.0% hydrogen peroxide solution. The reported density of 30% hydrogen peroxide is 1.135 g/cm3. (H2O2 = 34.0147 g/mol)
Solution:Assume that the mass of H2O2 solution is 100 g.Thus:Mass of H2O2 = (%H2O2 × Mass of solution) / 100% = (30.0% × 100 g) / 100% = 30.0 gMoles of...

1. Water can be formed from the synthesis reaction of hydrogen with oxygen:
2 H2 + O2 → 2 H2O
If the reaction begins with 5.12 moles of oxygen, O2, how many moles of water are produced?
n(O2):n(H2O)=1:2n(H2O)=5.12*2=10.24molAnswer: 10.24mol
