It can be both.
The reactant, because it is reacting to form the product of H2O.
Hydrogen can be a reactant or a product, it depends on the chemical reaction. Anything to the left of the arrow is consumed by the reaction and is thus a reactant, so hydrogen is a reactant in the reaction O2 + 2H2 -> 2H2O. A product is on the right of the arrow and is produced by the reaction, so hydrogen is a product in the reaction Zn + 2HCl -> ZnCl2 + H2
For copper, it is an element. It could be both reactant and product. While purifying copper will be the product. But copper would be the reactant in case of preparing hydrogen or copper sulphate salts.
I think Hydrogen Peroxide is a reactant,because hydrogen and oxygen are reactants so hydrogen peroxide should be a reactant.
2!
In some reactions water is a reactant, but in others it is a product. Ex: HCl + NaOH --> NaCl + water (water is a product) Na + water --> NaOH + hydrogen gas (water is a reactant)
The reactant, because it is reacting to form the product of H2O.
Water can be either a reactant, or a product. It really depends on the type of chemical equation. Here are examples of both water being on the reactant side, and the product side. Reactants 2H2O ===> 2H2 + O2 HCl + H2O ===> Cl- + H3O+ Products CH4 + 2O2 ===> CO2 + 2H2O 2H2O2 ===> 2H2O + O2

It is reactant!

the reactants are hydrogen and water, and the product is oxygen.
produce
A reactant exists at the beginning of a chemical reaction whilst a product exists at the end. They are alike in the fact that to get to a product you need to have a ready supply of the reactants. An example of a simple reactant/product reaction is shown below. Magnesium + Oxygen --> Magnesium Oxide Reactant + Reactant --> Products Hope this helps
if it is hydrogen gas, that is easier,2 If it is in water with 2 oxigen atoms in is not.
I think Hydrogen Peroxide is a reactant,because hydrogen and oxygen are reactants so hydrogen peroxide should be a reactant.
