$CuCl_2$ is an ionic compound composed of the metal cation $Cu^(2+)$ and 2 $Cl^(_)$ anions. The best way to identify the charge is to to use the Periodic table ....
1 Answers 1 viewsChlorine has a high electro negativity of 3.0. Copper like most metals has a low electro negativity, So the is ionic making the compound an ionic salt.

1 Answers 1 viewsReally, if you examine each molecule and atom as a unit, then almost everything is balanced already. We see one equivalent of $"Cu"^(2+)$ (copper(II)) on each side, and one equivalent...
1 Answers 1 viewsAluminum is oxidized to $Al^(3+)$. $Al(s) rarr Al^(3+) + 3e^(-)$ $(i)$ And cupric ion is reduced to zerovalent copper.... $Cu^(2+) + 2e^(-) rarr Cu(s)$ $(ii)$ We cross multiply to remove...
1 Answers 1 viewsI'd start by looking at what is the most complicated and unbalanced, as we can see there is only 1 $Cu$ on the left hand side but there is two...
1 Answers 1 viewsAqueous sodium chloride, $"NaCl"$, will not react with aqueous copper(II) sulfate, $"CuSO"_4$, because the two potential products are soluble in aqueous solution. The chemical equation given to you is...
1 Answers 1 viewsZinc metal is oxidized to $Zn^(2+)$, whereas $Cu^(2+)$ (as cupric chloride) is reduced to copper metal. We can write the individual redox equations: $ Cu^(2+) + 2e^(-)rarrCu(s) $ $Zn(s) rarr...
