Section 3 five types of reactions

1. Combination/Synthesis

2. Decomposition

3. Single Replacement

4. Combustion

5. Double Replacement

Section 3: Five Types of Reactions


1 combination synthesis
1. Combination/Synthesis

2 H2 + O2  2 H2O


1 combination synthesis1
1. Combination/Synthesis

“The Marriage”

only 1 product

A+ BAB

2H2 + O2

2H2O


2 decomposition
2. Decomposition

H2O2 H2 + O2


2 decomposition1
2. Decomposition

“The Break-up”

only 1 reactant

ABA+B

H2O2

H2+ O2


3 single replacement
3. Single Replacement

Zn + 2HCl  ZnCl2 + H2


3 single replacement1
3. Single Replacement

“Cuttin’ In”

1 element replaces another in a compound

A+BCAC+B

Zn + 2HCl

ZnCl2+ H2


4 combustion
4. Combustion

Burnin’

burning a hydrocarbon(CxHy) in O2

always forms CO2and H2O

CxHy+O2  CO2+H2O

CH4+2O2

CO2+2H2O


1–4 Redox

Synthesis

A0 + B0 → A+B–

SingleReplacement

C0 + A+B– → C+B– + A0

Zn + 2HCl  ZnCl2 + H2

2H2 + O2 2H2O

Decomposition

A+B– → A0 + B0

Combustion

CxHy + O2 → CO2 + H2O

+4

+

-2

-2

+

0

H2O2 H2 + O2

CH4 + 2O2 CO2 + 2H2O


5 double replacement
5. Double Replacement

NOT REDOX

NaCl + AgF  NaF + AgCl


5 double replacement1
5. Double Replacement

“Switchin’ Partners”

ions in two compounds “change partners”

AB+CDAD +CB

NOT REDOX

NaCl + AgF

NaF + AgCl
