write out the balanced reaction for magnesium and copper (I) chloride solution.

Question

Mg2(s) + 4CuCl2(aq) -> 2MgCl2(aq) + 4Cu(s)

is this right? i'm not sure exactly how to do this. Please help

Answer 1

Mg(s) + CuCl2(aq) ==> MgCl2(aq) + Cu(s)

Mg is monoatomic. You can remember the diatomic elements and their cousins. H2, N2, O2, F2, Cl2, Br2, I2, and their cousins P4 and S8. We write the others as one atom to the molecule.
