What is the product of combustion of hydrogen?

Explanation:
When hydrogen burns in oxygen, it reacts to form water and releases energy. In balanced form, 2H2 + O2 → 2H2O, showing that water is the product of this complete combustion. Hydrogen peroxide would require a different reaction pathway and isn’t produced by ordinary burning of hydrogen. Oxygen gas is a reactant, not a product, and hydrogen gas is the fuel, not the product.
