If a chemical reaction such as photosynthesis begins with 6 atoms of carbon C , how many atoms of carbon C should be in the prod
pochemuha
B. 6 atoms of carbon C
I would think this is the answer, because one can't just delete or add atoms; otherwise, the equation would be unbalanced. This also abides with the Law of Conservation of Mass.

Plus, I also came to that conclusion because if we look at the net equation of photosynthesis:
6C O_{2} + 6H_{2}O ––> C_{6}H_{12}O_{6} + 6O_{2}
The number of Carbon atoms is 6 on both the reagent's side and the product's side.
