If 10.5 g copper chloride react with 12.4 g aluminum what is the limiting reactant

copper chloride

Explanation:

From the balanced equation. it can be seen that 3 moles of copper chloride reacts with 2 moles of Al.

Thus 0.08 moles of copper chloride reacts with= moles of Al.

Thus copper chloride is the limiting reagent as it limits the formation of product and aluminium is the excess reagent as it is left unused. (0.46-0.05)=0.41 moles are in excess.

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).

a electronegativity decreases beacuse the size of nucleus is bigger.
