  2. 7.5 Types of Chemical Reactions

  3. Why is this important? Learn more about different kinds of Chemical Reactions. Click HERE! Knowing what kind of Chemical Reaction that you are working on makes it easier to predict and determine the product(s) of the reaction.

  4. Combination Reactions This reaction allows two elements or two compounds or an element and a compound to combine and form a new substance (single product). *Note* the product will always be a compound!

  5. The Equation is Simple! A AB + B  NEW COMPOUND! Either elements or compounds

  6. Combination of Nonmetals This is a simple combination reaction between Sulfur and Oxygen. Balancing is not needed, atoms are exact!

  7. Group A Metal + Nonmetal  ? When a Group A Metal is combined with a nonmetal it forms a combination of the metal cation and nonmetal anion Use the ionic charges to find their formula and then BALANCE! For example: 2K(s) + Cl2(g)  2KCl(s)

  8. Nonmetal Oxide + WaterAcid Some nonmetal oxides react with water to produce an acid, a compound that produces hydrogen ion in aqueous solution. For example: SO2(g) + H2O(l)  H2SO3 (aq)

  9. Metallic Oxides +WaterBase Metallic oxides react with water to form a base, a compound that contains hydroxide ion. Use ionic charges to get the formula for the product. For example: CaO(s) + H2O(l)  Ca(OH)2 (aq)

  10. Other Stuffs… B + AB A  This equation is very similar to Combination Reaction, but don’t get confuse! Remember that Combination Combines! whereas Decomposition  Decompose!

  11. Why don’t you try it? Find the product of Cu + O2  ? and balance the formula a) Cu + O2  CuO b) 2Cu + O2 2CuO c) 4Cu + O2  2Cu2O d) 5Cu + O2  CuO2 YES, THERE ARE 2 POSSIBLE ANSWER! Cu can be Copper(II) Oxide or Copper (I) Oxide

  12. Another One? No multiple choice this time! Find the formula and balance! Na2O + H2O  Sodium Hydroxide Na2O + H2O  2NaOH

  13. HOMEWORK! • Li+ O2? • Cl2O5+ H2O  Chloric acid 3. Na + Cl2 ?

  14. THANK YOU FOR WATCHING!
