Question

This chemical equation represents the burning of methane, but the equation is incomplete. What is the missing coefficient in both the reactants and the products? CH4 + ____O2 → CO2 + ____H2O

Answer 1

Your complete chemical equation is CH4+O2=CO3+H2O

Answer 2

Answer:
`CH_4+2O_2\rightarrow CO_2+2H_2O`

Step-by-step explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The balanced chemical equation for combustion of methane will be:

`CH_4+2O_2\rightarrow CO_2+2H_2O`
