Calcium sulphate, also known as Plaster of Paris, is made by calcining gypsum. The figure show two of the application of Plaster of Paris in medical applications.  Write balanced equation for the calcination reaction of gypsum, to produce calcium sulphate. Name 2 properties of calcium sulphate that make this material is suitable to be used for the application shown in figure above? Give 2 examples of application of Plaster of Paris, other than the application shown in figure above.
