Write balanced chemical equations for the following processes:
(i) $X e F$ undergoes hydrolysis.
(ii) $M n O$ is heated with conc. $H C l$ .

Open in App

Solution

(i) $X e F$ on hydrolysis:
$2 X e F (s) + 2 H_{2} O (l) ⟶ X e (g) + 4 H F (a q .) + O_{2} (g)$

(ii) $4 H C l + M n O_{2} ⟶ C l_{2} + M n C l_{2} + 2 H_{2} O$
