What is required for the combustion reaction to take place? 1

Combination reactions “combine” elements to form a chemical compound. As usual, oxidation and reduction occur together.

Equation: 2 H2 + O2 → 2 H2O

The sum of oxidation states in the reactants is equal to that in the products:

0 + 0 → (2)(+1) + (-2)

In this equation, both H2 and O2 are the molecular forms of their respective elements, and therefore their oxidation states are 0. The product is H2O: the oxidation state is -2 for oxygen and +1 for hydrogen.
