1.	Y' is obtained by the decomposition of a substance 'X'. Oxygen present in 'X' is univalent. 'Y' reacts with a neuteral oxide and evolves 'Z' which is composed of reddish brown fumes which turns moist blue litmus red. Identify 'X', 'Y' and 'Z'.
Answer» `H_(2)O_(2),H_(2)" and "CO_(2)` `H_(2)O_(2),O_(2)" and "NO_(2)` `KCIO_(3),Cl_(2)" and "O_(2)` `HgO,O_(2)" and "NO` Solution :`underset((X))(H_(2)O_(2))toH_(2)O_(2)+O_(2)` `underset((Y))(NO)+O_(2)tounderset((Z))underset(("reddish brown"))(NO_(2))` `O_(2)`(Y) is NEUTRAL towards litmus while `NO_(2)` is ACIDIC and HENCE turns MOIST bule to red
