Responses

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

3H2O + 3CO2 → C6H12O6 + 6O2
3 H 2 O + 3 CO 2 → C 6 H 12 O 6 + 6 O 2

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

6H2O + 6CO2 → C3H6O3 + 3O2

Answer 1

6H2O + 6CO2 → C6H12O6 + 6O2

This equation is balanced: C: 6 = 6, H: 12 = 12, O: 18 = 18, so it conserves matter (atoms).
