Here are the equations categorized as balanced or unbalanced:
- N2 + 3H2 → 2NH3 - Balanced
- 2C2H6 + 7O2 → 4CO2 + 5H2O - Balanced
- 4ZnS + 6O2 → 4ZnO + 2SO2 - Balanced
- 2Fe2O3 + 3C → 4Fe + 3CO2 - Balanced
- C3H8 + 5O2 → 3CO2 + 4H2O - Balanced
All of the equations listed are balanced, meaning the number of atoms for each element is the same on both sides of the reaction.
