A metal nitrate 'A' on heating gives yellowish brown coloured metal oxide along with brown gas 'B' and a colourless gas 'C'. Aqueous solution of 'A' on reaction with potassium iodide forms a yellow precipitate of compound 'D'. Identify 'A,B,C,D'. Also identify the types of both the reaction. Metal present in 'A' is used in alloy which is used for soldering purpose.

A= leadnitrate, B= nitrogen dioxide gas, C = oxygen gas , D = leadiodide.
The first reaction is a thermal decomposition reaction and 2nd one is double decomposition reaction.
