What is the action of H_(2)O_(2) on litmus?

Giving a suitable explanation for the contrast in the action of heat on the following: MgCl_2 . 6 H_2O and CaCl_2 . 6 H_2O .

The heat of solution of anhydrous CuSO_(4) is -66.5 kJ and that of CuSO_(4).5H_(2)O is 11.7 kJ . Calculate is the heat of hydration of CuSO_(4) .

Write the balance equation for the following Action of heat on Na_(2)CO_(3). 10H_(2)O

At 25^(@)C , when 1 mole of MgSO_(4) was dissolved in water, the heat evolved was found to be 91.2 kJ. One mole of MgSO_(4) . 7H_(2)O on dissolution gives a solution of the same composition accompanied by an absorption of 13.8 kJ. The enthalpy of hydration, i.e., DeltaH_(h) for the reaction MgSO_(4)(s) + 7H_(2)O(l)rarrMgSO_(4) . 7H_(2)O(s) :

Some properties of sulphuric acid are listed below. Choose the role played by sulphuric acid as A, B, C, or D which is responsible for the reactions. MgO + H_2SO_4 rarr MgSO_4 + H_2O
