Natural gas or methane is a fossil fuel. In a plentiful supply of air, it burns to give carbon dioxide and water. Write a balanc
Alex17521 [72]

Answer:

CH_4 + 2O_2 --> CO_2 + 2H_2O

Explanation:

The chemical formula for methane is CH_4

The chemical formula for oxygen is O_2

The chemical formula for carbon dioxide is CO_2

The chemical formula for water is H_2O

Methane burns in oxygen to give carbon dioxide and water:

CH_4 + O_2 --> CO_2 + H_2O

The balanced equation that will ensure an equal number of each atom on the left and right-hand sides of the equation would be:

CH_4 + 2O_2 --> CO_2 + 2H_2O
