A chloride of silicon contains 79.1 mass cl – A chloride of silicon containing 79.1 mass % Cl is a versatile compound with significant industrial applications. Its unique chemical composition and properties make it an essential component in the production of various chemicals and materials.
This chloride of silicon, commonly known as silicon tetrachloride (SiCl4), is a colorless liquid at room temperature with a pungent odor. It is highly reactive and reacts readily with water, releasing hydrogen chloride gas. Due to its reactivity, SiCl4 must be handled with proper safety precautions.
Chloride of Silicon
A chloride of silicon is a compound containing silicon and chlorine atoms. The chemical formula of a chloride of silicon that contains 79.1 mass % Cl is SiCl 4. This formula indicates that the compound contains one silicon atom and four chlorine atoms.
The mass percentage of Cl in SiCl 4can be calculated using the following formula:
“`Mass % Cl = (Mass of Cl / Mass of SiCl 4) x 100%“`
Substituting the atomic masses of Si (28.09 g/mol) and Cl (35.45 g/mol) into the formula, we get:
“`Mass % Cl = (4 x 35.45 g/mol / (28.09 g/mol + 4 x 35.45 g/mol)) x 100% = 79.1%“`
