Write balanced chemical equations for the following processes: (i) `XeF_(2)`, undergoes hydrolysis. (ii) `MnO_(2)`, is heated with conc. HCI

Answer» (i) `XeF_(2)` is hydrolysed to give Xe, HF and `O_(2)`
`2XeF_(2)(s)+2H_(2)O(l)to2Xe(g)+4HF(aq)+O_(2)(g)`
(ii) When maganese dioxide is heated with conc. hydrochloric acid it gives
`MnO_(2)+4HCltoMnCl_(2)+Cl_(2)+2H_(2)O`
