hay his your answer:---The metal nitrate (A) is Lead nitrate (Pb(NO₃)₂) On heating it produces Lead oxide, Nitrogen dioxide (B) and oxygen gas (C) 2Pb(NO₃)₂ → 2PbO + 4NO₂ + O₂ On reaction with potassium iodide mixture of lead iodide and potassium nitrate forms. Pb(NO₃)₂ + 2KI → PbI₂ + 2KNO₃ Alloy made of using lead is used in soldering purposes. Therefore A = (Pb(NO₃)₂) B = NO₂ C = O₂ D = PbI + KNO₃ (mixture of compounds)
