When electricity flows through water, the water molecules split into molecules of hydrogen and oxygen gas. how many oxygen (o2) molecules are produced from the splitting of two molecules of water (h2o) if the balanced equation for the reaction is as follows? 2h2o 2h2 + o2

1 Oxygen molecule

Explanation:

According to the law of conservation of matter, the number of atoms of each element involved in a chemical reaction stays the same no matter how they are arranged. So, even though oxygen is combined with hydrogen on the reactant side, the total number of oxygen atoms remains the same after the reaction takes place. There are two atoms of oxygen on the reactant side, and two on the product side.
