Question

Balance the chemical reaction of water

H2+02 — H20

Added photo plz if you can help

Answer 1

• Add 2 molecules of hydrogen peroxide and 2 molecules of water. Since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

Answer 2

H2+1/2O2-->H2O

since there are two atoms of hydrogen present in the reactants and in the product you don't need to add any number before H2

we add 1/2 before O2 because only 1 atom is needed for the water molecule
