Hydrogen and oxygen react vigorously to form water. If 120 hydrogen molecules are reacted with 200 oxygen molecules in a closed container define how many hydrogen, oxygen and water molecules will remain after the reaction is complete?
0 hydrogen + 80 oxygen + 120 water
20 hydrogen + 0 oxygen + 100 water
80 hydrogen + 0 oxygen + 400 water
0 hydrogen + 0 oxygen + 400 water
0 hydrogen + 140 oxygen + 120 water
