Which option is a balanced equation for photosynthesis?

C6H12O6 + 6O2 6CO2 + 6H2O

CO2 + H2O C6H12O6 + O2

6CO2 + 6H2O C6H12O6 + 6O2

6C6H12O6 + 6O2 6CO2 + H2O

6CO2 + 6H2O -> C6H12O6 + 6O2

Explanation: Photosynthesis is a process by which green plants use energy from the sun to manufacture their own food from carbon dioxide and water. In the reaction, 6 molecules of water combines 6 molecules of carbon dioxide to form one molecule of glucose and 6 molecules of oxygen.

The equation for the reaction is shown below

6CO2 + 6H2O --> C6H12O6 + 6O2

In balancing a chemical equation, the total mass of the reactants must be equal to the total mass of the products because law of conservation of mass states that matter can neither be created nor be destroyed in an ordinary chemical reaction.

the fossil record provides evidence of a common ancestor to many species.
