1.	Lattice energy in sodium chloride is x kJ. Assuming the same interionic distance, what will be the lattice energy of magnesium sulphide?
Answer» Solution :The charge MAGNITUDES of ions in NaCl are1 and 1 respectively. The produce of `q_(1)` and `q_(2)=1xx1=1` The charge magnitude of ions in magnesium sulphide are 2 and 2 respevetively. The product of `q_(1)` and `q_(2)=2xx2=4` Hence lattice energy of MgS `=4X KJ`.
