    A bluish green coloured compound 'A' on heating gives two products 'B' and 'C'. A metal 'D' is deposited on passing H_(2) through heated 'B'. The compound 'A' and 'B' are insoluble in water. 'B' is black in colour, dissolves in HCI and on treatment with K_(4)[Fe(CN)_(6)] gives a chocolate brown ppm of compound 'E'. 'C' is colourless, odourless gas and turns lime water milkly.
