The specific heat of selenium is approximately 0.321 J/g°C at room temperature. This value indicates the amount of heat required to raise the temperature of one gram of selenium by 1°C.
The molar heat capacity of selenium is 25,363 J/mol.K.
Selenocysteine is the amino acid that contains selenium. It is incorporated into proteins during the translation process via a specific codon and tRNA. Selenium plays a role in antioxidant defense and thyroid hormone metabolism.
Selenium is a non-metal element, so it does not have a distinct color in its pure form. However, when combined with other elements in compounds, selenium can exhibit colors ranging from red to black, depending on the specific compound.
There is one mole of selenium in one mole of selenium tetrafluoride, as the formula for selenium tetrafluoride is SeF4. Therefore, there is 1 mole of selenium in 1 mole of selenium tetrafluoride.
I am not aware of a specific company that re-coats selenium onto a cylindrical drum, as this process is not commonly done due to the toxicity and health risks associated with selenium. It is more common to replace the drum or find alternative solutions.
