What is ‘Lattice energy’?

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

What is kinetic energy ?

(A): Oxides of II A group elements are stable (R) : Oxides of IIA group elements have high lattice energy.

What is mechanical energy ?

What is potential energy ? Derive an expression for the gravitational potential energy .

Statement I: Crude common salt is hydrosco pic because of impurities CaSO_(4) and MgSO_(4) Statement II : The increase in solubility of hydroxides down the group 2 elements is due to increase in lattice energy

What is energy ?

AB is an ionic solid. The ionic radii of A^+ and B^(-) are respectively r_c and r_a . Lattice energy of AB is proportional to

By using Born-Haber cycle to calculate the crystal lattice energy of NaCl, discuss the heats, involved in all the changes.
