Question

Balance the equations

CH4 + 2O2 => CO2 + H2O​

Answer 1

Answer:

First look at the C atoms. At first glance they are balanced with 1 C on each side.

Now look at the H atoms. They are not balanced. There are 4 H atoms on the left side and 2 H atoms on the right. Place a coefficient of 2 in front of the

. We now have 4 H atoms on both sides

Now look at the O atoms. They are not balanced. There are 2 O atoms on the left side and 4 on the right. Place a coefficient of 2 in front of the

. We now have 4 O atoms on both sides.

The equation is now balanced. Each side has 1 C atom, 4 H atoms, and 4 O atoms.

Answer 2

Explanation:

To balance the hydrogen atoms, put a 2 in front of H2O: CH4 + O2 CO2 + 2H2O. The oxygen atoms can be balanced by putting a 2 in front of the O2 on the left: CH4 + 2O2 CO2 + 2H2O. ... It can be checked by counting the number of atoms of each element on both sides of the new equation.
