Why don't the two individual molecular formulae add up to the same number of atoms in the sucrose product? A) Oxygen must be burned/consumed during the reaction. B) In a dehydration reaction, a water molecule (H2O) is removed from the final molecule formed. C) In a dehydration reaction, a water molecule (H2O) is added to the final molecule formed. D) Hydrogen must be burned/consumed during the reaction.
