A One atom of hydrogen reacts with two atoms of oxygen to give one molecule of water
B Two atoms of hydrogen react with two atoms of oxygen to give two molecules of water
C One molecule of oxygen reacts with one molecule of hydrogen to give two molecules of water
D One molecule of hydrogen reaccts with two molecules of oxygen to give three molecules of water
E One molecule of oxygen reacts with two molecules of hydrogen to give two molecules of water
