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

How many total atoms of oxygen are on the reactants side?

SELECT AN ANSWER

6


12


18


2

Answer 1

18

Step-by-step explanation:

**Subscripts represent atoms in chemical formulas

The subscript in glucose is 6, and multiply the 6 by the 2 subscript in the other oxygen reactant and then added to get a total of 18 atoms

6 + 6(2) = 6 + 12 = 18
