The equation which is balanced and represents the correct product(s) is :
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
This reaction is unfavourable in forward direction as Li2O is more stable than K2O . In eqn 3 charge on should be -2 inspite of +2.
In eqn 4, product should be .
Only, is balanced and represents correct products.
