Answer 2

Plaster of Paris, or simply plaster, is a type of building material based on calcium sulfate hemihydrate, nominally CaSO4*0.5H2O. It is created by heating gypsum to about 150ºC. CaSO4 · 2H2O → CaSO4 · 0.5H2O + 1.5H2O (released as steam).
A large gypsum deposit at Montmartre in Paris is the source of the name. When the dry plaster powder is mixed with water, it re-forms into gypsum, initially as a paste but eventually hardening into a solid. The structure consists of sheets of Ca²+ and SO4²- ions held together by hydrogen bonds in the water molecules. The grip between these sheets is easily broken, so plaster is fairly soft.
