The fact that can always be deduced about the reactants when the products of a reaction are known is **the number of atoms in the reactants**. This is because of the principle of conservation of mass, which states that the total number of atoms must remain constant in a chemical reaction. Therefore, while we may not always know the exact number or state of the reactants, we can deduce that the total number of atoms in the reactants will be equal to the total number of atoms in the products.
