1.	(A)is a colourless solid, itmetal when heated and gives of a gas (B) Which is supporter of combustion , if heating is contimed the white of the solid disuppears , When (A) isheatyed with an aqueous NaOH solution , an alkaline gas (C ) is evolved ,When gas(B) is leasted with sodumine ,a colourless solid (D) is formed .When (D) is heated with dil H_(2)SO_(4) a colourless liquid (F) is formed . The mass ofcompound E is
