Could someone help me with these molecular formulas, i don't know what im doing wrong. For this example, i did it like this and it says its incorrect. Could you solve the the equations below your way and i match it to mines? Thank you so much

Fe (s) + Ni(NO3)2 (aq) =Fe(NO3)2 (aq) + Ni (s)




FeCl3(s) + K3PO4(aq)=
CaCl2(s) + K3PO4(aq)
FeCl3(s) + KNO3(aq)
Fe2(SO4)3 (aq) + K3PO4(aq)
CuBr2(s) + NH4OH(aq)
ZnBr2 (s) + NH4OH(aq)
CuBr2 (s) + NH4NO3(aq)
CuSO4 (s) + NH4OH(aq)
NiCl2 (s) + Na2CO3(aq)
MgCl2 (s) + Na2CO3(aq)
NiCl2 (s) + NaNO3(aq)
NiSO4 (s) + Na2CO3(aq

    Your example probably wanted you to write Fe(NO3)3 and balance it.

    Products for #2. FePO4 + KCl
    #3 Ca3(PO4)2 + KCl
    #4 No reaction.
    #5. FePO4 + K2SO4
    This exercise is to give you practice on predicting and balancing.
    Rxns tend to take place if
    a. the metal(alone) is ABOVE the ion(compound) in the activity series.
    b. a ppt (insoluble) forms.
    c. a gas forms
    d. a weak electrolyte is formed.
