Responses

6H2O + 6CO2 → C3H6O3 + 3O2
6H 2 O + 6CO 2 → C 3 H 6 O 3 + 3O 2

6H2O + 10CO2 → C6H12O6 + 4O2
6H 2 O + 10CO 2 → C 6 H 12 O 6 + 4O 2

6H2O + 6CO2 → C6H12O6 + 6O2
6H 2 O + 6CO 2 → C 6 H 12 O 6 + 6O 2

3H2O + 3CO2 → C6H12O6 + 6O2

Answer 1

6H2O + 6CO2 → C6H12O6 + 6O2

This equation is balanced: C:6 = 6, H:12 = 12, O:18 = 18, so it conserves matter (same number of each atom on both sides).
