#21 TYPES OF CHEMICAL REACTIONS NOTES
#22 Types of reactions practice

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

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

25. WHAT TYPE OF CHEMICAL REACTION IS THIS?
Exit Ticket
Carbonic acid is an unstable compound. At room temperature, carbonic acid produces carbons dioxide and water according to the following equation:
H2CO3  CO2 + H2O
