Balanced Equation for Photosynthesis
What is Balanced Equation for Photosynthesis?
The balanced symbol equation for photosynthesis is 6CO2 + 6H2O to C6H12O6 + 6O2, with light energy and chlorophyll written around the reaction arrow rather than as reactants. Six molecules of carbon dioxide and six of water yield one molecule of glucose and six of oxygen, so carbon, hydrogen and oxygen atoms balance on both sides.
