Question

If aluminum is the limiting reactant, SOME/NONE/ALL of it will still be visible after the reaction completes. If CuCl2 is the limiting reactant,SOME/NONE/ALL of the aluminum will still be visible.

Answer 1

If aluminum is the limiting reactant, none of it will still be visible after the reaction completes.

If CuCl2 is the limiting reactant, some of the aluminum will still be visible.

Answer 2

If aluminum is the limiting reactant, NONE of it will still be visible after the reaction completes.

If CuCl2 is the limiting reactant, SOME of the aluminum will still be visible.

Step-by-step explanation:

• Any chemical reaction, if the reactants are not in equimolar ratios, contains limiting reactant and leftover reactant.

• The limiting reactant in a chemical reaction is the reactant that is totally consumed when the chemical reaction is complete. The amount of product formed is limited by this reagent, since the reaction cannot continue without it.

• The leftover reactant is the reactant that is in excess and not consumed completely and some of it remains in the reaction mixture.

So,

If aluminum is the limiting reactant, NONE of it will still be visible after the reaction completes.

and,

If CuCl2 is the limiting reactant, SOME of the aluminum will still be visible.
