- Definition of BeS:
BeS, also known as Beryllium sulfide, is a chemical compound consisting of two elements: Beryllium and Sulfur. The molar mass of BeS is 41.08, and the atomic masses of BeS are 9.0122 for Beryllium and 32.065 for Sulfur. The BeS molecule consists of a positive Beryllium ion and a negative sulfide ion.
- Properties of BeS:
2.1 Physical properties of BeS: BeS is solid at room temperature. This substance is white or pale blue in color, and odorless. The pH of BeS cannot be determined because it does not dissolve in water.
2.2 Chemical properties of BeS: BeS reacts very easily with water to form Beryllium hydroxide (Be(OH)2) and Hydrogen sulfide (H2S).
- Common chemical equations of BeS:
Reaction with water:
BeS + 2H2O -> Be(OH)2 + H2S
- Synthesis of BeS:
4.1 Laboratory synthesis of BeS: BeS can be synthesized by heating beryllium with sulfur. The chemical equation is: Be + S -> BeS
4.2 Industrial synthesis of BeS: In industry, BeS is commonly produced by the reaction between beryllium chloride and hydrogen sulfide according to the equation: BeCl2 + H2S -> BeS + 2HCl.
