Match the reactions in Column I with nature of the reactions `//` type of the products in Column II.

Answer

A, B, C, D

Explanation

(A) `5AgNO_(3)(aq.)+3overset(0)(l)_(2)("excess")+3H_(2)Oto overset(+V)(HlO_(3))+5Agoverset(-1)(l)+5HNO_(3)`
So it is redox and disproportionation reaction. Agl insoluble in water.
(B). `3K_(2)overset(+VI)(MnO_(4))(aq)+2CO_(2)(g)to2Koverset(+VII)(MnO_(4))+Moverset(+VI)(nO_(2))+2K_(2)CO_(3)`
So it is redox and disproportionation reaction. `MnO_(2)` insoluble in water.
(C) `2overset(0)(C)+Na_(2)overset(+VI)(Cr_(2))O_(7)overset(Delta)toCr_(2)overset(+VII)(O_(3))+Na_(2)overset(+IV)(CO_(3))+overset(+II)(CO)uarr`
So it is redox reaction, `Cr_(2)O_(3)` (green pigment) is insoluble i water.
(D). `overset(+II)(C)uCl_(2)(aq)+overset(0)(Cu)(s)to overset(+I)(Cu_(2))Cl_(2)(s)`.
So it is redox and comproportionation reaction. `Cu_(2)Cl_2` is insoluble in water.
