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:First: the coefficients give the number of molecules (or atoms) involved in the reaction. In the example reaction, two molecules of hydrogen react with one molecule of oxygen and produce two molecules of water. Second: the coefficients give the number of moles of each substance involved in the reaction.
