1. Types of Chemical Reactions (6)
Chemical reactions are classed into 6 main types. The next 6 slides reviews very briefly each type.

2. Synthesis Reaction
2 or more simple substances form a more complex one. Sometimes called a combination reaction.
Ex) A + B  AB or
A + BC  ABC
2Na + Cl2  2NaCl

3. Decomposition Reactions
a more complex substance breaks down into 2 or more simple substances.
Example ABC  A + BC or
ABC  AB + C or etc
H2CO3  H2O + CO2

4. Single Replacement Reaction
Sometimes called Single Displacement.    
1 element replaces another in a compound.
Example A + BC  AC + B or
A + BC  BA + C
2Na + 2H2O  2NaOH + H2

5. Double Replacement Reaction
Sometimes called Double Displacement.
different atoms in 2 different compounds replace each other.
Example AB + CD  AD + CB
MgCO HCl  MgCl H2CO3

6. Neutralization Reaction
Often incorrectly called water forming
an acid + base react to produce water and a salt
(special type of Double Replacement Reaction)
example HA + BOH  H2O + BA
HCl + NaOH  H2O + NaCl

7. (Organic)Combustion Reaction
Sometimes classified as a special type of decomposition.
Organic compound (contains CH sometimes O or S) and oxygen react to produce CO2 and H2O. Examples
CH O2  CO2 + H2O
CHO O2  CO2 + H2O
CHOS + O2  CO2 + H2O + SO2
CH O2  CO2 + 2H2O
