Question

In the chemical reaction: 2 h 2 (g) o2 (g) → 2 h2o (g), with 8 grams of h 2 (2 grams/mole) and 16 grams of o2 (32 grams/mole) and the reaction goes to completion, what is the excess reactant and how much of that would remain

Answer 1

Use stoichiometric ratio to determine which is in excess and which is limiting
