Question

If one molecule of glucose (C6H12O6) reacts completely with three molecules of oxygen (O2), what is the TOTAL number of atoms that will be in the products? A) 24 B) 30 C) 38 D) 48

Answer 1

I believe it would be 30 because there are 24 atoms in one molecule of glucose and 6 atoms in three molecules of oxygen.

Answer 2

Answer;

30 atoms

Explanation;

When glucose, C6H12O6, reacts with oxygen it produces carbon dioxide and water. If a molecule of glucose reacts completely with three molecules of oxygen, then 30 atoms would be produced because there are 24 atoms in glucose and 6 atoms in oxygen molecules.

The equation for the reaction would be;

C6H12O6 + 6O2(g) → 6CO2(g) + 6 H2O(l)
