Classifying Reactions

  • The five general types of reaction are:

  • Combination

  • Decomposition

  • Single-replacement

  • Double-replacement

  • Combustion.


11.2

Classifying Reactions

  • Combination Reactions

    • A combination reaction is a chemical change in which two or more substances react to form a single new substance.


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.

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.


11.2

Classifying Reactions

  • The activity series of metals lists metals in order of decreasing reactivity.


for Conceptual Problem 11.6

Problem Solving 11.17 Solve Problem 17 with the help of an interactive guided tutorial.


11.2

Classifying Reactions

  • Double-Replacement Reactions

    • A double-replacement reaction is a chemical change involving an exchange of positive ions between two compounds.


for Conceptual Problem 11.7

Problem Solving 11.18 Solve Problem 18 with the help of an interactive guided tutorial.


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.

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?


11.2

Predicting the Products of a Chemical Reaction

  • The number of elements and/or compounds reacting is a good indicator of possible reaction type and thus possible products.
