Unformatted text preview: glass and ceramics. Silicon carbide (SiC) is used as an industrial abrasive. Quartz crystals vibrate at a constant resonant frequency when excited, and so they are used as timing devices in everything from wristwatches to radios. Silicon polymers, or silicones, are used to make caulk, electrical insulation, hydraulic fluids, anti-foaming agents, water-repellent coatings for fabrics, cosmetic implants, and many other goods. Motorcycle mechanics use silicone grease in applications that see high temperatures, for example on the backs of brake pads. Unlike petroleum-based greases, silicone grease does not liquefy and run away when heated. The central goal of this assessment is that you demonstrate that you can apply chemical thinking to explain and make predictions about the chemical reactivity of silicon and silicon compounds of central importance in modern society....
