Question

Write a balanced chemical equation describing the oxidation of chlorine gas by the copper (III) ion to form the chlorate ion and copper (II) in an acidic aqueous solution. Use the smallest whole number coefficients possible.

I have tried the following answers and I have no idea what to do to make it correct:

C1, (g) + 10Cu+3(aq) + 120H (aq) —2010z (aq) + 10Cu+2 (aq) + 6H20(1)

Thank you so much for your help!

Here is the hint I was given:

One way to determine the balanced equation for a redox reaction is to write a preliminary expression relating the reactants and products, do an oxidation number analysis, and balance atoms and charge. In an acidic aqueous solution, hydrogen ions and water may be used to balance atoms.
