Flexi Says: The chemical equation for photosynthesis is:
6CO2 + 6H2O + Light Energy → C6H12O6 + 6O2
This chemical equation shows that six molecules of carbon dioxide (6CO2) react with six molecules of water (6H2O) in the presence of light energy to form one molecule of glucose (C6H12O6) and six molecules of oxygen gas (6O2).
