![**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).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F041ecdf6-35b6-494f-8c83-99b4545c3454%2F4c44fd3f-92e5-491f-b8e6-207ae13c0981%2Frlld1r_processed.png&w=3840&q=75)
