Presentation Transcript

  1. Oxygen: Properties, Uses and Impacts

  2. Quick Chemical Changes with Oxygen Combustion: • A rapid chemical change involving oxygen and a fuel that releases large amounts of energy. • Gasoline, propane, and natural gas are common fuels. • Combustion releases energy that is stored in the fuel molecules as thermal energy and light.

  3. The Fire Triangle

  4. Slow Chemical Changes with Oxygen • Not all of the chemical changes that use oxygen are rapid. • For example, during cellular respiration our cells use oxygen to extract energy stored in nutrient molecules like sugar. The waste energy is in the form of heat (Ie: body heat!)

  5. Rusting: • Rusting is a slow chemical change that converts iron into a reddish-brown compound called iron oxide. • Alloys that contain iron, such as steel, can also rust. • Both oxygen and water are needed for rusting to occur, and the presence of salt makes it happen faster.
