complete balanced equation :
Mg (s) + Zn (NO3)2 (aq) ---------------------> Mg(NO3)2(aq) + Zn (s)
explanation:
Mg is more acitive metal . it is due to lower reduction potential in the electronchemical series Eo = -2.37 V
Zn less active metal. it is due to higher reduction potential in the electronchemical series Eo = - 0.76 V
so Mg can replace Zn from its solutions
