Solution

Given reaction is

$H g O \to H g + O_{2}$

We see that $O = 2$ on RHS and $O = 1$ on LHS.

$∴$ Multiply LHS by $2$ to balance oxygen reaction becomes,

$2 H g O \to H g + O_{2}$

Now, we see that $H g = 1$ on RHS and $H g = 2$ on LHS.

$∴$ Multiply $H g$ by $2$ .

Balanced reaction is

$2 H g O_{(s)} △ - \to 2 H g_{(l)} + O_{2 (g)}$
