Final answer:
In the chemical reaction CH₄ + 2O₂ → CO₂ + 2H₂O, there are four hydrogen atoms on the right side, as obtained from two water molecules each having two hydrogen atoms.
Step-by-step explanation:
The question asks how many hydrogen atoms are on the right side of the balanced chemical reaction CH₄ + 2O₂ → CO₂ + 2H₂O. In this reaction, methane (CH₄) reacts with oxygen (O₂) to produce carbon dioxide (CO₂) and water (H₂O).
To find out the number of hydrogen atoms on the product side, we look at the water molecule. Each molecule of water contains two hydrogen atoms. Since we have two water molecules as indicated by the coefficient '2' in front of H₂O, we multiply the number of hydrogen atoms per molecule by the number of water molecules. Therefore:
Number of hydrogen atoms in one H₂O molecule = 2
Number of water molecules = 2
Total number of hydrogen atoms on the right = 2 x 2 = 4.
Thus, there are four hydrogen atoms on the product side of the reaction.
