Mn (maganese)
If something being reduced, it loses an oxygen, and if something is being oxidized, it gains an oxygen. The element being reduced is called the oxidizer; the element being oxidized is called the reducer. (just remember, it's called the opposite of what happens to it) In the context of your equation, which i assume to be CuCl2+KNO3-->Cu(NO3)2+2KCl, potassium (or the K) is losing oxygen, which therefore makes that the oxidizer, the one being reduced.
2KClO3 ---(MnO2)---> 2KCl + 302 **The MnO2 goes over the arrow.
2KCl(aq) + Cu(NO3)2(aq) -> 2KNO3(aq) + CuCl2(aq)
Decomposition by heat: (KClO3)s --> (KCl)s + (O2)g
