Question

CH4 +
__02 →
2 H20+ __CO2
Balance the equations

Answer 1

The balanced equation is given below:

CH4 + 2O2 → 2H2O + CO2

The coefficient of O2 and CO2 are 2 and 1 respectively.

Step-by-step explanation:

CH4 + O2 → 2H2O + CO2

The above equation can be balanced as follow:

There are a total of 4 atoms of O on the right side and 2 atoms on the left. It can be balance by putting 2 in front of O2 as shown below:

CH4 + 2O2 → 2H2O + CO2

Now we can see that the equation is balanced.

Therefore, the coefficient of O2 and CO2 are 2 and 1 respectively.
