Balance the Equation:
Balance the
C
and
H
first. There are
2
carbon atoms on the left side, and
1
carbon atom on the right side. There are
6
hydrogen atoms on the left side and
2
hydrogen atoms on the right side.
Add a coefficient of
2
in front of the carbon dioxide, and a coefficient of
3
in front of the water.

We now have equal numbers of
C
and
H
atoms on both sides. However, the
O
is not balanced.
We have
7
O
atoms on the right side, and
3
on the left side. Place a coefficient of
3
in front of the
O
2
on the left side.

We now have a balanced equation, with

6
hydrogen atoms on both sides, and
7
oxygen atoms on both sides.
