Types of chemical reactions
The 5 reactions
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.
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
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
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.
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
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
