4. TYPE OF REACTION: SYNTHESIS
Examples:
A + B  AB
2O2 + N2  2NO2
Info:
Forming new
compounds

5. TYPE OF REACTION: DECOMPOSITION
Examples:
AB  A + B
2KCL3  2KCl + 3O2
Info:
Breaking
compounds

6. TYPE OF REACTION: SINGLE
REPLACEMENTExamples:
A+ BC  AC + B
Pb + FeSO4  Fe + PbSO4
Info: An element takes the place of
another element in a compound

7. TYPE OF REACTION: DOUBLE
REPLACEMENTExamples:
AB+ CD  CB + AD
RbNO3 + BeF  BeNO3 + RbF
Info: Two compounds break apart and
form new compounds

8. TYPE OF REACTION: COMBUSTION
Examples:
A + O2  AO2 + Heat
CH3OH + O2  CO2 + 2H2O + Heat
Info: Always has Oxygen as a reactant.
Produces heat as a product. O2 Burns!

9. TYPE OF REACTION: ACID-BASE
Examples:
H+ + OH-  Water + Salt
HCN + NaOH  H2O + NaCN
Info: Acids ( H+) and bases (OH-) are the
reactants that neutralizes to form salt and
water as products.
