To determine which of the given equations is balanced, we can count the number of atoms of each element on both sides of the equation.
1. **C3H8 + 5 O2 → 3 CO2 + 4 H2O**
- Left: C: 3, H: 8, O: 5 × 2 = 10 → Total = C: 3, H: 8, O: 10
- Right: C: 3, H: 4, O: 3 × 2 + 4 × 1 = 6 + 4 = 10 → Total = C: 3, H: 4, O: 10
- Not balanced (hydrogen is not equal).
2. **C3H8 + 3 O2 → CO2 + H2O**
- Left: C: 3, H: 8, O: 3 × 2 = 6 → Total = C: 3, H: 8, O: 6
- Right: C: 1, H: 2, O: 2 + 1 = 3 → Total = C: 1, H: 2, O: 3
- Not balanced (carbon and hydrogen are not equal).
3. **C3H8 + 11 O2 → 3 CO2 + 8 H2O**
- Left: C: 3, H: 8, O: 11 × 2 = 22 → Total = C: 3, H: 8, O: 22
- Right: C: 3, H: 8, O: 3 × 2 + 8 × 1 = 6 + 8 = 14 → Total = C: 3, H: 8, O: 14
- Not balanced (oxygen is not equal).
4. **2 C3H8 + 4 O2 → 2 CO2 + 4 H2O**
- Left: C: 2 × 3 = 6, H: 2 × 8 = 16, O: 4 × 2 = 8 → Total = C: 6, H: 16, O: 8
- Right: C: 2 × 1 = 2, H: 4 × 2 = 8, O: 2 × 2 + 4 × 1 = 4 + 4 = 8 → Total = C: 2, H: 8, O: 8
- Not balanced (carbon and hydrogen are not equal).
After checking all equations, it appears none are correctly balanced. However, based on correcting the third balanced form:
**The correct equation that is balanced is**:
**C3H8 + 5 O2 → 3 CO2 + 4 H2O**.
The first equation originally stated is balanced upon re-evaluation of the counting.
The balanced status of:
**C3H8 + 5 O2 → 3 CO2 + 4 H2O** is accurately described, confirming it does represent the balancing of carbon, hydrogen, and oxygen in equal proportions.
Hence, the balanced equation is:
**C3H8 + 5 O2 → 3 CO2 + 4 H2O (correctly balanced)**.

- Right: C: 3, H: 4, O: 3 × 2 + 4 × 1 = 6 + 4 = 10 → Total = C: 3, H: 4, O: 10

- Right: C: 1, H: 2, O: 2 + 1 = 3 → Total = C: 1, H: 2, O: 3
- Not balanced (carbon and hydrogen are not equal).
3. **C3H8 + 11 O2 → 3 CO2 + 8 H2O**
- Left: C: 3, H: 8, O: 11 × 2 = 22 → Total = C: 3, H: 8, O: 22
- Right: C: 3, H: 8, O: 3 × 2 + 8 × 1 = 6 + 8 = 14 → Total = C: 3, H: 8, O: 14
