Question

Balance the following chemical equations: i) CH4+O2 CO2+H2O ii) Na + H2O NaOH +H2​

Answer 1

Answer:

ok

Explanation:

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

H

2

O

. We now have 4 H atoms on both sides.

CH

4

+ O

2

→

CO

2

+ 2H

2

O

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

O

2

. We now have 4 O atoms on both sides.

CH

4

+ 2O

2

→

CO

2

+ 2H

2

O

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