Thermal decompositon of a compound `(X)` yields , a basic oxide `(Y)` and an acidic oxide `(Z)` simultanously. The acidic oxide `(Z)` can be absorbed by alkaline `KOH`. Indentify `(X),(Y)` and `(Z)`. |

Answer» `Xoverset(Delta)(rarr)underset("oxide")underset("Basic")(Y)+underset("oxide")underset("Acidic")(Z)` `underset((X))(CaCO_(3))overset(Delta)(rarr)underset((Y)0underset("basic oxide")(CaO)+underset((Z))underset("Acidic oxide")(CO_(2))` `underset((Z))(CO_(2))+KOHrarrK_(2)CO_(3)+H_(2)O` Hence `(X),(Y)` and `(Z)` are `CaCO_(3), CaO` and `CO_(2)` respectively. |
