1. Types of chemical reactions
The 5 reactions

2. Combustion reaction What is a combustion reaction?
Combustion is “fire” or “burning”.
What do we need to burn?
A combustion reaction is a combination of a hydrocarbon and oxygen to make carbon dioxide and water.

3. Synthesis reaction What is a synthesis reaction?
Synthetic is “man made”.
Synthesis means to make.
What does this mean in a reaction?
A synthesis reaction is a combination of 2 or more reactants to make one product.
H2 + O2  H2O

4. Decomposition reaction
What is a decomposition reaction?
Decompose means to break down.
How does this relate to a reaction?
A decomposition reaction is when one reactant breaks down into multiple products.
H2O  H2 + O2

5. Replacement reaction What is a replacement reaction?
Replace means to take the place of.
What does this mean for a reaction?
Replacement reactions occur when one substance takes the place of another in a compound.

6. Single replacement What is a single replacement reaction?
One thing is being replaced.
A single replacement reaction is when one chemical takes the place of a chemical already in a compound.
AB + Y  AY + B
AB + Y  YB + A

7. Double replacement What is a double replacement reaction?
This is where 2 chemicals in different compounds are replaced.
A double displacement reaction is when 2 compounds switch partners.
AB + XY  AY + XB
AB + XY  AX + BY
