What are the Types of Chemical Reactions?1. Synthesis Reaction2. Decomposition Reaction3. Single Replacement Reaction4. Double Replacement Reaction5. Combustion Reaction

Page 4: Objective: To identify the five types of  chemical equations

Synthesis Reactions (Combination Reactions)A chemical change in which 2 or more

substances form a single new substance.

Key = 1 product

General Equation: A + B C

Page 5: Objective: To identify the five types of  chemical equations

ExamplesH2 + O2

K + Cl2

Mg + O2

Remember: BrINClHOF!!

Page 6: Objective: To identify the five types of  chemical equations

ExamplesH2 + O2 H2O

K + Cl2 KCl

Mg + O2 MgO

Remember: BrINClHOF!!

Page 7: Objective: To identify the five types of  chemical equations

Decomposition ReactionsA chemical change in which a single

compound breaks down into two or more simpler substances.

Opposite of synthesis reaction.

Key = 1 reactant

General Equation: A B + C

Page 8: Objective: To identify the five types of  chemical equations

ExamplesH2O

KCl

H2O2

Page 9: Objective: To identify the five types of  chemical equations

ExamplesH2O H2 + O2

KCl K + Cl2

H2O2 H2 + H2O

Page 10: Objective: To identify the five types of  chemical equations

Single Replacement ReactionsA chemical change in which one element replaces

a second element in a compound.A cation must replace a cation, and an anion must

replace an anion.To determine if the reaction occurs, you must use

the activity series.

Key = 1 element & 1 compound as reactants

General Equation: A + BC B + AC or

A + BC C + AB

Page 11: Objective: To identify the five types of  chemical equations

ExamplesCu + AgNO3

K + H2SO4

Na + LiCl

F2 + Na Cl

Page 12: Objective: To identify the five types of  chemical equations

ExamplesCu + AgNO3 CuNO3 + Ag

K + H2SO4 K2SO4 + H2

Na + LiCl No Reaction

F2 + Na Cl NaF + Cl2

Page 13: Objective: To identify the five types of  chemical equations

Double Replacement ReactionsA chemical change involving the exchange of

cations between two compounds.

Takes place in aqueous solution and must produce a precipitate, a gas, or a covalent compounds such as water.

Page 14: Objective: To identify the five types of  chemical equations

To determine if the reaction occurs, you must use the solubility rules.

Key = 2 compounds as reactants

General Equation: AB + CD AD + CB

Page 15: Objective: To identify the five types of  chemical equations

ExamplesCaSO4 + NaCl

KI + Pb(NO3) 2

BaBr2 + KCl

Page 16: Objective: To identify the five types of  chemical equations

ExamplesCaSO4 + NaCl No Reaction

KI + Pb(NO3) 2 PbI2 + KNO3

BaBr2 + KCl No Reaction

Page 17: Objective: To identify the five types of  chemical equations

Combustion ReactionA chemical change in which an element or

compound reacts with oxygen producing energy in the form of heat or light.

A hydrocarbon and oxygen are always the reactants.

Carbon dioxide and water are always products.

General Equation: CxHy + O2 CO2 + H2O

Page 18: Objective: To identify the five types of  chemical equations

ExamplesCH4 + 2O2 CO2 + 2H2O
