How many molecules of water would result if two molecules of glucose combined with 12 molecules of oxygen?

Answer 1

Twelve.

Glucose is C6H12O6, so two molecules of glucose would give you:

12 carbon atoms

24 hydrogen atoms

12 oxygen atoms

The 12 molecules of oxygen would give 24 oxygen atoms, for 48 total atoms of oxygen.

So...each carbon atom would take two oxygen atoms to give 12 molecules of carbon dioxide, and each remaining oxygen atom would take two hydrogen atoms to give 12 molecules of water.

Answer 2

If two molecules of glucose combine with 12 molecules of oxygen, the resulting chemical reaction would produce 12 molecules of carbon dioxide, and 12 molecules of water. Therefore, 12 molecules of water would result.
