Answer:
CH₄ + 2O₂ —> CO₂ + 2H₂O
Explanation:
The thermochemical equation for the combustion of methane can be obtained as follow:
Methane (CH₄) under goes combustion in the presence of air (O₂) to produce carbon dioxide (CO₂) and water (H₂O). This can be represented in the equation below:
CH₄ + O₂ —> CO₂ + H₂O
Thus, we can balance the equation as follow:
CH₄ + O₂ —> CO₂ + H₂O
There are 4 atoms of H on the left side and 2 atoms on the right side. It can be balance by putting 2 in front of H₂O as shown below:
CH₄ + O₂ —> CO₂ + 2H₂O
There are a total of 4 atoms of O on the right side and 1 atom on the left side. It can be balance by putting 2 in front of O₂ as shown below:
CH₄ + 2O₂ —> CO₂ + 2H₂O
Now the equation is balanced.
Answer:
They are both water
