We have already seen that a candle can continue to burn in chlorine. However if turpentine oil, another hydrocarbon, is sprayed into a jar of chlorine, or if a filter paper dipped in turpentine oil is dropped into a jar of chlorine, the reaction is vigorous. In the se..

Sulphur occurs in the earth's crust to the extent of 0.05% mostly as metal sulphides and sulphates. It also occurs in the elemental form in large underground beds. Another major source of sulphur is H 2 S present in the natural gas and crude oil. Sulphur exists in combined state..
