There are 12 CO2 molecules, each with 2 oxygen atoms, and 14 H2O molecules, each with 1 oxygen atom. So, the total number of oxygen atoms is (12 * 2) + (14 * 1) = 24 + 14 = 38.
A. 38
The products are on the right side. Multiply the big number in front times the small subscript number. There are 24 (12×2) + 14 (14×1) = 38
