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.
Many compounds are found in crystal form with water attached. These compounds are called hydrates and the crystals with water attached are called hydrated crystals.The formula for the hydrated crystal tells how many water molecules are attached to each formula unit of crystal.For example, hydrated calcium nitrate is written: Ca(NO3)2 (4 H2O and is called calcium nitrate tetrahydrate.he formula for the hydrated crystal tells how many water molecules are attached to each formula unit of crystal.
