1 Fabrication shops and machine shops have overlapping capabilities, but fabrication shops generally concentrate on metal preparation and assembly as described above. 2  By comparison, machine shops also cut metal, but they are more concerned with the machining of parts on machine tools.
A hydrated salt is a solid that includes water molecules within its crystal structure A student heated a 9.10-gram sample of a hydrated salt to a constant mass of 5.41 grams What percent by mass of?nhydrous is the term for a hydrate with water heated off. when a  hydrated salt is heated, it loses water of crystallization leaving  an anhydrous salt. Edit. Share to: Answered.
The solid contains one or more hydrates â salts that crystallize with a definite number of water molecules in each formula unit. For instance, barium chloride dihydrate, BaCl 2 Â· 2H 2 O, is a hydrate containing two molecules of water (water of crystallization) for each BaCl 2 unit.You will heat the solid to drive off the water of crystallization, and from the loss in mass, calculate the percent of water that was present.he solid contains one or more hydrates â salts that crystallize with a definite number of water molecules in each formula unit.
