Answer:
2Al + 3Ni(NO₃)₂ = 3 Ni + 2 Al (NO₃)₂
Explanation:
we have aluminum that is added to nickel (ii) nitrate solution. Nickel (ii) means here nickel having electron charge of +2 . NO₃ having electron charge -1. So nickel nitrate solution be (NO₃)₂
Aluminium on reaction replaces nickel and form Aluminium Nitrate with some amount of nickel. After balancing both side
2Al + 3Ni(NO₃)₂ = 3 Ni + 2 Al (NO₃)₂
