Predict whether the following reactions would occur spontaneously in aqueous solution at 25°C.
Assume that the initial concentrations of dissolved species are all 1.0 M. 

(a)  Ca(s)   +   Cd2+(aq)   --->     Ca2+(aq)   +   Cd(s)

(b)   2Br-(aq)   +   Sn2+(aq)  --->   Br2(l)   +   Sn(s)

(c)    2Ag(s)    +     Ni2+(aq)    --->   2Ag+(aq)    +    Ni(s)

(d)   Cu+(aq)   +   Fe3+(aq)    --->     Cu2+(aq)   +   Fe2+(aq)
