  1. 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.

  2. 11.2 Classifying Reactions Classifying Reactions • The five general types of reaction are synthesis, decomposition, single-replacement, double-replacement, and combustion.

  3. 11.2 Classifying Reactions • Synthesis Reactions • A synthesis or combination reaction is a chemical change in which two or more substances react to form a single new substance.

  4. for Conceptual Problem 11.4

  5. 11.2 Classifying Reactions • Decomposition Reactions • A decomposition reaction is a chemical change in which a single compound breaks down into two or more simpler products.

  6. for Conceptual Problem 11.5

  7. 11.2 Classifying Reactions • Single-Replacement Reactions • A single-replacement reaction is a chemical change in which one element replaces a second element in a compound.

  8. 11.2 Classifying Reactions • The activity series of metals lists metals in order of decreasing reactivity.

  9. for Conceptual Problem 11.6

  10. 11.2 Classifying Reactions • Double-Replacement Reactions • A double-replacement reaction is a chemical change involving an exchange of positive ions between two compounds.

  11. for Conceptual Problem 11.7

  12. 11.2 Classifying Reactions • Combustion Reactions • A combustion reaction is a chemical change in which an element or a compound reacts with oxygen, often producing energy in the form of heat and light.

  13. for Conceptual Problem 11.8

  14. 11.2 Predicting the Products of a Chemical Reaction • Predicting the Products of a Chemical Reaction • How can you predict the products of the five general types of reactions? • The number of elements and/or compounds reacting is a good indicator of possible reaction type and thus possible products.
