What is the bond enthalpy of C-H bond of CH_(4) ?

Sea water contains small quantities of MgCl_(2) and MgS_(4) Sea water is treated with slaked limeto precipitate the dissolved salty as Mg(OH)_(2) The Mg(OH)_(2) is dissolved in a little quantity of HCI and MgCl_(2)6H_(2)O is crystallised from solution. The hydrated MgCl_(2) is heated in a current of dry HCl gas to get anhydrous MgCl_(2) Pused anhydrous MgCl_(2) is subjected to electrolysis. Magnesium deposited at cathode.

Number of water molecules present in the hydrated state of MgSO_(4)

(A) : Sulphate is estimated as BaSO_(4) and not as MgSO_(4) (R) : Ionic radius of Mg^(2+) is smaller than that of Ba^(2+) .

(A) : Na_2 SO_4 is more soluble in water while BaSO_4 , is less soluble (R) : Lattice energy of Na_2 SO_4 is greater than that of BaSO_4

Assertion:When CuSO_4 is dissolved in water, the solution is warmed up. Reason: Hydration energy of CuSO_4 is higher than its lattice energy
