What is the balanced chemical equation for the galvanic cell reaction expressed using shorthand notation below?

Al(s)|Al3+(aq)||Ni2+(aq)|Ni(s)

3 answers

Al(s) + Ni^+2 ==>Al^+3 + Ni(s)
I will let you balance it. Remember that the electron exchange must balance as well as the ions themselves.
It may be easier for you to look at the two half cells.
Al(s) ==> Al^+3 + 3e
Ni^+2 + 2e ==> Ni(s)
2 Al(s) + 3 Ni2+(aq)-->2 Al3+(aq) +3 Ni(s)

is this correct?
yes
