  • When ignited, magnesium ribbon reacts with oxygen in the surrounding air to form magnesium oxide, a white solid. This is a combination reaction. Observing Why do you think this reaction was once used in flashbulbs for photography? <br />
  • When orange-colored mercury(II) oxide is heated, it decomposes into its constituent elements: liquid mercury and gaseous oxygen. Comparing and Contrasting How are the two reactions pictured so far similar? How are they different? <br />
  • The alkali metal potassium displaces hydrogen from water and forms a solution of potassium hydroxide in a single-replacement reaction. The heat of the reaction is often sufficient to ignite the hydrogen. Inferring Why are alkali metals stored under mineral oil or kerosene? <br />
  • Aqueous solutions of potassium carbonate and barium chloride react in a double-replacement reaction to form the white precipitate barium carbonate. Potassium chloride, the other product of the reaction, remains in solution. <br />
  • Methane gas reacts with oxygen from the surrounding air in a combustion reaction to produce carbon dioxide and water. Inferring What else is produced in this reaction? <br />

  • 2. 11.2 Types of Chemical Reactions The heat and smoke of burning charcoal are the products of a combustion reaction. Combustion is one of the five general types of chemical reactions. If you can recognize a reaction as being a particular type, you may be able to predict the products of the reaction. © Copyright Pearson Prentice Hall Slide 2 of 42
