reacting with potassium iodide forms a yellowish precipitate of compound "D". identify "A" "B" "C" "D". identify both type of reaction. metal present in "A"is used in makeing paints


The Brainliest 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
       Pb(NO₃)₂ + 2KI → PbI₂ + 2KNO₃
then,A = (Pb(NO₃)₂)
                         B = NO₂
                         C = O₂
                         D = PbI + KNO₃ (mixture of compounds)
