#19. TYPES OF CHEMICAL REACTIONS NOTES

18. Objectives 4 Types of Reactions:
Describe four types of chemical reactions.
Classify a chemical equation as one of four types of chemical reactions.
4 Types of Reactions:
Synthesis Reaction
Decomposition Reaction
Single-Displacement Reaction
Double-Displacement Reaction
Video

19. Synthesis Reactions:
Synthesis reaction is a reaction in which two or more substances combine to form one new compound.
Pattern: A + B  AB
Ex. N2 + H2  NH3

20. Decomposition Reactions:
A decomposition reaction is a reaction in which a single compound breaks down to form two or more simpler substances. Decomposition is the reverse of synthesis.
Pattern: AB  A + B
Ex. Ag2O  Ag + O2

21. Single-Displacment Reactions:
A single-displacement reaction is a reaction in which one element replaces another element that is part of a compound. The products of single-displacement reactions are a new compound and a different element.
In a single-displacement reaction, a more reactive element can displace a less reactive element in a compound.
Pattern: A + BX  AX + B
Ex. K + MgBr  KBr + Mg

22. Double-Displacment Reactions:
A double-displacement reaction is a reaction in which ions from two compounds exchange places. One of the products of this type of reaction is often a gas or a precipitate.
Pattern: AX + BY  AY + BX
Ex. KNO3 + H2CO3  K2CO3 + HNO3
