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.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

hope this !
