Chapter 8: Reactions in Aqueous Solutions
Purpose
Chemical reactions can be classified by considering what the reactions are, what the products are, or how they
change from one into another. Types of chemical reactions include synthesis, decomposition, combustion, single
and double replacements.

Essential Understandings

Major types of chemical reactions are
Synthesis (A + B → AB)
Decomposition (BC → B + C)
Single displacement (A + BC → B + AC)
Double displacement (AB + CD → AD + CB)
Combustion (CxHy + O2 → CO2 + H2O)
Essential Knowledge, and Skills
In order to meet this standard, it is expected that students will

Classify types of chemical reactions as synthesis, decomposition, single displacement, double
displacement, neutralization, and/or combustion.

Recognize equations for redox reactions and neutralization reactions.

Classify the different types of decomposition reactions.

Classify the difference in combustion reactions when there is excess or limited oxygen.
