Answer» cbda bcdea adcb cdab Solution :(i) OXYGEN in is prepared by heating of hydrogen peroxide. (II) Carbon burns with SPARKLES and carcking sound to give `CO_(2)`. (iii) Sulphur burns with BRILLIANT blue flame to give `SO_(2)`. (iv) `P_(2)O_(2)` appears as dense WHITE fumes when phosphorus is burnt with oxygen.
