# Brief Explanations:
- **Law of Conservation of Mass**: In a chemical reaction, atoms are neither created nor destroyed. They are just rearranged.
- **Counting Atoms in Photosynthesis Equation**:
    - **Carbon (C)**:
        - Reactants: In $6CO_2$, the number of C atoms is $6\times1 = 6$.
        - Products: In $C_6H_{12}O_6$, the number of C atoms is $6$. So, the number of C atoms is the same on both sides.
    - **Hydrogen (H)**:
        - Reactants: In $6H_2O$, the number of H atoms is $6\times2=12$.
        - Products: In $C_6H_{12}O_6$, the number of H atoms is $12$. So, the number of H atoms is the same on both sides.
    - **Oxygen (O)**:
        - Reactants: In $6CO_2$, the number of O atoms from $CO_2$ is $6\times2 = 12$, and in $6H_2O$, the number of O atoms from $H_2O$ is $6\times1=6$. Total O atoms on reactant side $=12 + 6=18$.
        - Products: In $C_6H_{12}O_6$, the number of O atoms is $6$, and in $6O_2$, the number of O atoms is $6\times2 = 12$. Total O atoms on product side $=6+12 = 18$.

# Answer:
A. No new substances are produced during the process of photosynthesis since it is a chemical reaction - **Incorrect** (photosynthesis is a chemical reaction that produces new substances like glucose ($C_6H_{12}O_6$) and oxygen ($O_2$) from carbon dioxide ($CO_2$) and water ($H_2O$)).
B. There are more carbon (C) atoms on the products side of the equation than there are on the reactants side - **Incorrect** (as shown above, C atoms are balanced: 6 on reactant side (from $6CO_2$) and 6 on product side (from $C_6H_{12}O_6$)).
C. A new substance is produced during photosynthesis because photosynthesis is a chemical reaction - **Correct** (photosynthesis is a chemical reaction where reactants ($CO_2$ and $H_2O$) are transformed into new substances ($C_6H_{12}O_6$ and $O_2$)).
D. There are fewer hydrogen (H) atoms on the products side of the equation than there are on the reactants side - **Incorrect** (H atoms are balanced: 12 on reactant side (from $6H_2O$) and 12 on product side (from $C_6H_{12}O_6$)).
E. The number of oxygen (O) atoms is the same on the reactants and products side of the chemical reaction - **Correct** (as calculated above, 18 O atoms on reactant side and 18 O atoms on product side).

So the correct answers are C and E.
