Verified Answer :

The conservationĀ  of
law states that in a chemical reaction mass is neither created or destroyed
therefor the total amount of mass for the reactant for photosynthesis are 6
carbon dioxides 6 waters and sunlight. The mass of each reactant adds to equal
up to the mass of the product. Which are going to be 1 glucose and 6 oxygen.
Which will then equal the amounts of each atom on both ends of this equation.
This can be confusing at some points due to the energy (sunlight) is the
reaction in the chemical equation and not the product or outcome. The energy
can be converted from one end to another in photosynthesis. Energy is converted
form sunlight into sugar or glucose which the body then breaks down for energy.
