To determine which option best describes the number of atoms for each element in the chemical reaction, we need to analyze each option for the count of carbon, hydrogen, and oxygen atoms on the reactant side and the product side.
Let's break down each option:
A.
- Reactants: 6 carbon, 12 hydrogen, 12 oxygen
- Products: 1 carbon, 2 hydrogen, 3 oxygen
B.
- Reactants: 6 carbon, 12 hydrogen, 8 oxygen
- Products: 6 carbon, 12 hydrogen, 18 oxygen
C.
- Reactants: 6 carbon, 12 hydrogen, 18 oxygen
- Products: 6 carbon, 12 hydrogen, 18 oxygen
D.
- Reactants: 6 carbon, 12 hydrogen, 18 oxygen
- Products: 6 carbon, 12 hydrogen, 3 oxygen
Based on these counts:
- For option A, the reactants and products do not match at all.
- For option B, the oxygen count on the reactant and product sides does not match (8 vs. 18).
- For option C, both sides match perfectly: 6 C, 12 H, and 18 O.
- For option D, the oxygen count on products does not match the reactants (18 vs. 3).
Thus, the best description of the number of atoms for each element in the reaction, where the reactants and products balance, is:
C. There are 6 carbon atoms, 12 hydrogen atoms and 18 oxygen atoms on the reactant side and 6 carbon atoms, 12 hydrogen atoms and 18 oxygen atoms on the product side.
