As we learned

Oxides and hydroxides of Li and Mg -

1. They are much less soluble

2. Their hydroxides decomposes on heating

3. Their oxides don't combine with excess oxygen to give superoxide

-

In $Li_{2}O+2KCl\rightarrow 2LiCl+K_{2}O$

This reaction is unfavourable in forward direction as Li2O is more stable than K2O . In eqn 3 charge on $\left [ Mg\left ( E\: DT\: A \right ) \right ]$ should be -2 inspite of +2.

In eqn 4, product should be $K_{3}\left [ Cu\left ( CN \right )_{4} \right ]$ .

Only, $\left [ CoCl\left ( NH_{3} \right )_{5} \right ]^{+}+5H^{+}\rightarrow CO^{2+}+5NH_{4}^{+}+Cl^{-}$  is balanced and represents correct products.

Option 1)

Option 2)

Option 3)

Option 4)
