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.
Gas hydrate is an ice-like crystalline form of water and low molecular weight gas (e.g., methane, ethane, carbon dioxide).On Earth, gas hydrates occur naturally in some marine sediments and within and beneath permafrost.Gas hydrates have also been inferred on other planets or their moons.t the molecular level, gas hydrate consists of gas molecules surrounded by cages of water molecules. Each water cage encloses a space of a particular size, and only a gas molecule small enough to fit within this site can be hosted in that specific hydrate structure.
