Chemistry help?!?!?!?!?!?

an element always has an oxidation of zero so Zn and H2 has a oxidation of zero, HCl ---- h has an oxidation of +1 and x+1=0, x= -1---> so Cl is -1. ZnCl2-------- since since theres 2 Cl then its x( since we dont know what Zn is) +2(-1)=0 --------> x+2(-1)=0, x= +2 so in conclusion Zn =0, H=+1, Cl=-1, Zn=+2, Cl= -1, H=0-------------------------------> Zn is being oxidized because it is increasing from 0 to +2 and H is reduced because it is decreased from +1 to 0----------------------- your welcome :)
