Which of the following metals will not evolve $H_2$ gas from dilute $H_2SO_4$ solution?

How would you determine the standard electrode potential of the system $Mg^{2+} | Mg$?

The electrode potentials are given as follows:
$Fe_{(aq)}^{3+} + e^- \to Fe_{(aq)}^{2+}$; $E^o = 0.771 \, V$
$I_{2(s)} + 2e^- \to 2I_{(aq)}^-$; $E^o = 0.536 \, V$
For the cell reaction $2Fe_{(aq)}^{3+} + 2I_{(aq)}^- \to 2Fe_{(aq)}^{2+} + I_{2(s)}$,the value of $E^o_{cell}$ is:

The standard potential of a $Co^{2+} | Co$ electrode is $-0.28 \ V$ and the standard potential of the cell $Pt | Ti^{2+}(aq.), Ti^{3+}(aq.) || Co^{2+}(aq.) | Co_{(s)}$ is $0.09 \ V$. What is the standard potential of the $Ti^{2+}(aq.) | Ti^{3+}(aq.)$ electrode (in $V$)?

Using the standard electrode potentials given below,identify the correct statements from the following.
$Fe^{2+} + 2e^{-} \longrightarrow Fe ; E^{\circ} = -0.44 \ V$
$Cu^{2+} + 2e^{-} \longrightarrow Cu ; E^{\circ} = +0.34 \ V$
$Ag^{+} + e^{-} \longrightarrow Ag ; E^{\circ} = +0.80 \ V$
$(i)$ Copper can displace iron from $FeSO_4$ solution.
$(ii)$ Iron can displace copper from $CuSO_4$ solution.
$(iii)$ Silver can displace copper from $CuSO_4$ solution.
$(iv)$ Iron can displace silver from $AgNO_3$ solution.

Arrange the following metals in the order in which they displace each other from the solution of their salts: $Al, Cu, Fe, Mg$ and $Zn$.
