Answer:
The balanced equation is given below:
CH4 + 2O2 → 2H2O + CO2
The coefficient of O2 and CO2 are 2 and 1 respectively.
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.
