Which of the following statements are incorrect ?

`CaH_2` is also called hydrolith

`BeCl_2` in vapour phase exist as polymeric

`MgSO_4` is less soluble than `CaSO_4` in water

`MgCO_3` decomposes at lower temperature than `BaCO_3` .

`SO_(3)` is stronger oxidising agent and more acidic than `SO_(2)`

Selenium forms only two oxoacids i.e., selenous acid `(H_(2)SeO_(3))` and selenic acid `(H_(2)SeO_(4))`

The acidic strength and oxidation power of oxoaicds is greater in `+6` oxidation state than in `+4`.

The reducing character of oxides of group 16 elements increases in the order `SO_(2)ltSeO_(2)ltTeO_(2)`
