\textbf{98 --} Considering the following half-reactions at $E^\circ$, which statement is correct?
$$E^\circ(\mathrm{Cl_2/2Cl^-}) = +1.36\ \mathrm{V} \qquad E^\circ(\mathrm{Sn^{4+}/Sn^{2+}}) = +0.15\ \mathrm{V} \qquad E^\circ(\mathrm{Cu^+/Cu}) = +0.52\ \mathrm{V}$$
(1) $\mathrm{Cl^-(aq)}$ is a stronger reducing agent than $\mathrm{Sn^{2+}(aq)}$, and $\mathrm{Cu^+(aq)}$ is a stronger oxidizing agent than $\mathrm{Sn^{4+}(aq)}$.
(2) $\mathrm{Sn^{4+}(aq)}$ can oxidize $\mathrm{Cu(s)}$ under suitable conditions and produce energy.
(3) If metal X reacts naturally with $\mathrm{Sn^{4+}(aq)}$, it certainly also reacts with chlorine gas.
(4) The reaction: $\mathrm{2Cu(s) + Cl_2(g) \rightarrow 2Cu^+(aq) + 2Cl^-(aq)}$ proceeds naturally.
