Study the balanced chemical reaction.

H2 + O2 → H2O2
(M H2 = 2.02 g/mol; M H2O2 = 34.02 g/mol)

If 100.0 g of hydrogen peroxide (H2O2) is produced, what percent of the product is hydrogen?

A) 50.0% is hydrogen.
B) 94.1% is hydrogen.
C) 5.94% is hydrogen.
D) 12.5% is hydrogen.

1.aluminum chloride (alcl3), and sodium hydroxide (naoh) can react to form aluminum hydroxide (al(oh)3) and sodium chloride (nacl).    you have 13.4 g of aluminum chloride and 10.0 g of sodium hydroxide. answer the following questions: •what is the balanced equation for this reaction? •if you use all 13.4 g of aluminum chloride, how many grams of aluminum hydroxide can be formed? work must be shown to earn credit •if you use all 10.0 g of sodium hydroxide, how many grams of aluminum hydroxide can be formed? work must be shown to earn credit •how many grams of aluminum hydroxide will actually be made?     which reagent is limiting? explain your answer.
