This is a double displacement reaction that will form solid aluminum nitrate and aqueous cobalt(II) nitrate.
The balanced equation for the reaction is:
3Co(NO3)2 + 2Al(NO3)3 → 3Co(NO3)3 + 2Al(NO3)2
This reaction can be represented as a total ionic equation:
3Co^2+(aq) + 6NO3^-(aq) + 2Al^3+(aq) + 6NO3^-(aq) → 3Co(NO3)3(s) + 2Al^3+(aq) + 6NO3^-(aq)
And the net ionic equation is:
3Co^2+(aq) + 6NO3^-(aq) + 2Al^3+(aq) → 3Co(NO3)3(s) + 2Al^3+(aq)
