We know that,

All nitrates are soluble in water.

All chlorides are soluble in water with the exception of those formed with silver , lead , mercury ions as all halides are soluble.

Sulphates are soluble in water.

Hydroxides are not soluble in water.

Hence, copper(II) hydroxide is not soluble in water.

A mineral is a naturally occurring, inorganic solid, with a definite chemical composition. They cannot be in liquid or gas state. They exists only in solid state.

Here are the differences between Diamond and Graphite :

From the above analysis, Diamond is harder than Graphite because of the difference of crystalline structures.

The process of absorbtion of rain water by the soil on the earth is called infiltration. By this process, the rain water that falls on the soil becomes ground water.

Permanent hardness of water may be removed by the addition of Sodium Carbonate.

The first step in photosynthesis is to split the water molecule using sun light.
