1.	Which following are in correct
Answer» `BeCO_(3) gt mgCO_(3) gt CaCO_(3) gt SrCO_(3) gt BaCO_(3)` (solubility) `BeF_(2) gt MgF_(2) gt CaF_(2) lt SrF_(2) lt BaF_(2)` (solubility) `Beo gt MgO gt CaO gt SRO gt BaO` (radius ratio) `Ba gt Sr gt Ca gt Mg gt Be` ( hydration enthalpy) SOLUTION :Decreasing radius ratio `(M^(2+)//O^(2-))` `BaO gt SrO gt CaO gt mgO gt BeO` Decreasing hydration ENERGY `Be gt mg gt Ca gt Sr gt Ba`
