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.

The amount of organic material can be determined by ignition. Organic material is made of carbon compounds, which when heated to high temperatures are converted to carbon dioxide and water. In the ignition process, a dry solid sample is heated to a high temperature. The organic matter in the soil is given off as gases.This results in a change in weight which allows for calculation of the organic content of the sample. Oven-dry the sample to remove water (see soil moisture). Weigh a crucible and lid, evaporating dish and cover, or other covered container.he organic matter in the soil is given off as gases. This results in a change in weight which allows for calculation of the organic content of the sample. Oven-dry the sample to remove water (see soil moisture).
