The com-pound O2F2 is a vigorous and potent oxidizing and fluo-rinating agent. Are oxidation states or formal charges more ...What special property of the noble gases makes them unreactive? The boiling points and melting points of the noble gases increase steadily from He to Xe. Explain. In most compounds the solid phase is denser than the liquid phase. Why isn’t this true for water? It takes 15 kWh (kilowatt-hours) of electrical energy to produce 1.0 kg of aluminum metal from aluminum oxide by the Hall–Heroult process. Compare this to the amount of energy necessary to melt 1.0 kg of aluminum metal. ...Indium(III) phosphide is a semiconducting material that has been frequently used in lasers, light-emitting diodes (LED), and fiberoptic devices.
