2H_(2)+O_(2)arrow 2H_(2)O 1) How many moles of water form if 10 moles of oxygen react? 2) How many moles of hydrogen are used to make 368 of water?

1) According to the balanced chemical equation, 1 mole of oxygen reacts with 2 moles of hydrogen to produce 2 moles of water. Therefore, if 10 moles of oxygen react, 20 moles of water will be formed.2) According to the balanced chemical equation, 2 moles of hydrogen are used to produce 2 moles of water. Therefore, if 368 moles of water are produced, 368 moles of hydrogen will be used.
