Question

ON HEATING GREEN COLOURED FERROUS SULPHATE CRYSTALS, REDDISH BROWN SOLID IS LEFT AND SMELL OF A GAS HAVING ODOUR OF BURNING SULPHURIS EXPERIENCED?
IDENTIFY THE TYPE IF CHEMICAL REACTION?

Answer 1

Because it get decompose in fe SO2 and SO3 i hope it is

Answer 2

On heating 'green' coloured 'ferrous sulphate crystals', "reddish brown solid" is left and 'smell' of a gas having 'odour of burning sulphur' is experienced. The reaction is a "thermal decomposition reaction".

EXPLANATION:

'Thermal decomposition reaction' is also called as 'thermolysis' and is "chemical decomposition" caused by heat. In this reaction,the need of heat is to break the 'bonds' in the compound. The decomposition temperature is the 'temperature' at which the compound decomposes.
