Answer:

2 moles of hydrogen gas reacts with 1 mole of oxygen gas to yield 2 moles of water. 4 grams of hydrogen gas reacts with 32 grams of oxygen gas to yield 36 grams of water. Oxygen gas is insufficient since it is only 4 grams. This means that all oxygen gas will react to a proportionate amount of hydrogen to form water.
