1.	(1 ) Among the alkaline earth metals BeO is insoluble in water but other oxides are soluble. Why? (ii) State Diffusion Law.
Answer» SOLUTION :Lattice energy of BEO is comparatively higher than the hydrogen energy . Therefore it is almost insoluble in water. Whereas other alkaline earth metals oxides have high ? Ydration energy. Hence they are soluble in water. (ii)Diffusion is the spreading of molecules of a substance throughout ·a space or a second substance. Diffusion REFERS to the ~bility of the gases to mix with each other. E.g., Spreading of something such as brown tea LIQUID spreaqing through the water in a tea cup
