Consider the following reaction: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 7O₂: How many oxygen atoms are required to balance the above equation?
Answer: 6
Explanation
6CO₂ + 6H₂O → C₆H₁₂O₆ + 7O₂
The given reaction is the photosynthesis equation, where carbon dioxide and water form glucose and oxygen.
To balance oxygen atoms, the reaction requires 6 oxygen molecules (O₂), which contain 12 oxygen atoms on both sides.
