Water
anhydrous means if a substance contains NO water it is anhydrous. but if it is hydrated it contains water.
Anhydrous salts prepared by evaporating the water contained in a hydrated salt. However, anhydrous salts are non-electrolytes, meaning they can't pass an electric current.
As a general term, a substance is said to be anhydrous if it contains no water.
Weighing an anhydrous substance with a cover on helps prevent moisture from the air from being absorbed by the substance, which could affect the accuracy of the measurement. By keeping the cover on during weighing, the substance is protected from exposure to moisture or other contaminants.
Hydrouse is; containing combined water (especially water of crystallization as in a hydrate)
(of a substance, esp. a crystalline compound) containing no water.
Anhydrous basis refers to expressing the concentration of a substance without considering any water present in the sample. It is commonly used in chemistry to provide a more accurate representation of the actual concentration of the substance of interest. By expressing values on an anhydrous basis, any water content in the sample is excluded from the calculations.
Chromium is a likeley element to be contained in a substance with a brilliant yellow color.
To calculate purity on an anhydrous basis, you first need to determine the mass of the pure substance in the sample and the total mass of the sample, excluding any water content. This is typically done by drying the sample to remove moisture and then weighing it. The purity percentage can then be calculated using the formula: [ \text{Purity (%)} = \left( \frac{\text{mass of pure substance}}{\text{mass of anhydrous sample}} \right) \times 100 ] This gives you the purity of the substance relative to its anhydrous form.

The technical term for heat contained in a substance is "thermal energy". It refers to the energy that a substance possesses due to its temperature.
"They" blow the gas over some hygroscopic substance, like anhydrous CaCl2.
