The following are some statements related to VA group hydrides I) Reducing property increases from NH_(3) to BiH_(3) II) Tendency to donate lone pair decreases from NH_(3) to BiH_(3) III) Ease of replacing H with Cl decreases from NH_(3) to BiH_(3) IV) Ease of formation of hydrides decreases from NH_(3) to BiH_(3) The correct statement are

The thermal stability of alkaline earth metal carbonates increases from Be to Ba. This is because

Assertion : Acidic character of group 16 hydrides increases from H_(2)O" to "H_(2)Te . Reason : Thermal stablility of hydrides decreases down the group.

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : Barium carbonate is insoluble in water and is highly stable. Reason (R) : The thermal stability of the carbonates increases with increasing cationic size. Choose the most appropriate answer from the options given below :

Select incorrect statement about alkaline earth metals: (A) Solubility of sulphates decreases down the group (B) Solubility of hydroxides decreases down the group (c) Thermal stability of carbonates increases down the group D) Basic nature increases down the group
