Question

1pt Copper chloride and aluminum react to produce

aluminum chloride and copper. Which of the
following is the correctly balanced chemical
equation for this reaction?
O A. CuCl, + Al -> AICI, + u
O B. 3CuCl, + Al -> AlCl, + 2Cu
OC. 3CUCI, + 2Al -> 2AICI, + 3Cu
OD. CuCl, + 3Al -> AICI, + 2Cu

Answer 1

None of the above

but it must be:

for Copper(I)chloride

3CuCl + Al ==> AlCl3 + 3Cu

for Copper (II) chloride

3CuCl2 + 2Al ==> 2AlCl3 + 3Cu
