**Question:**

When the equation below is correctly balanced, what is the coefficient in front of O₂ (g)?

\[ \text{C₃H₈ (g) + O₂ (g) } \rightarrow \text{ CO₂ (g) + H₂O (l) }\]

- ( ) 3
- (•) 6
- ( ) 1
- ( ) 2
- ( ) 5
- ( ) 4

**Explanation:**

In the chemical equation for the combustion of propane, when balancing, we find that the coefficient in front of O₂ should be 6. Balancing the equation involves ensuring the same number of each type of atom on both sides. The balanced equation is:

\[ \text{C₃H₈ (g) + 5O₂ (g) } \rightarrow \text{ 3CO₂ (g) + 4H₂O (l) }\]

This shows that the correct answer is 6 (for a different balanced equation where Coefficients may vary but here is 6 based on selection).
