Question

What reduction half-reaction happens when zinc reacts with nickel(II) chloride? Zn(s) + NiCl2(aq) ZnCl2(aq) + Ni(s)

Answer 1

Zn(s) + NiCl2(aq) --> ZnCl2(aq) + Ni(s)

Answer 4

I think it's Ni(s) --> Ni2+(aq) + 2e−
but I want to make sure I'm right

Answer 5

The oxidation state of an uncombined element is zero.
\[Zn(s) + NiCl2(aq)\rightarrow ZnCl2(aq) + Ni(s)\]
Zn(s)-->Zn+2(aq)+2e-
Ni(+2)+2e--->Ni

Answer 6

oh so it's Zn(s) --> Zn2+(aq) + 2e−

Answer 7

yes thats right

Answer 8

Ni(+2)+2e--->Ni
