A combustion reaction took place each time you used the Bunsen burner to burn methane gas (CH4). Write a balanced chemical equation for the combustion of methane. *HINT: All hydrocarbon combustion reactions need oxygen as a reactant and form the same two products.

The answer to your question is    CH₄ + 2O₂  ⇒  CO₂  +  2H₂O

Explanation:

Data

Methane = CH₄

Oxygen = O₂

Process

A combustion reaction is a kind of chemical reaction in which an organic compound reacts with oxygen to generate water and carbon dioxide.

Chemical reaction

                   CH₄ + O₂  ⇒  CO₂  +  H₂O

             Reactants   Elements    Products

                    1                   C                1

                    4                  H                2

                    2                  O                3

Balanced chemical reaction

                   CH₄ + 2O₂  ⇒  CO₂  +  2H₂O

             Reactants   Elements    Products

                    1                   C                1

                    4                  H                4

                    4                  O                4

the answer is c.the valence of the atoms combine .
