Question:

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) 2Br2(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)
