Answer: The chemical equation for photosynthesis is 6CO2 + 6H2O + sunlight --> C6H12O6 + 6O2
Explanation: In the above equation, CO2 is carbon dioxide, H2O is water, C6H12O6 is glucose and O2 is oxygen. In this reaction, six molecules of carbon dioxide react with six molecules of water in the presence of sunlight to produce one molecule of glucose and six molecules of oxygen.
