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

8 What is what? ____ RbNO3 + ____ BeF2  ____ Be(NO3)2 + ____ RbF
____ P4 + ____ O2  ____ P2O3 ____ C3H8 + ____ O2  ____ CO2 + ____ H2O ____ KClO3  ____ KCl + ____ O2 ____ Na +____ I2  ____ NaI ____ KI + ____ Cl2  ____ KCl + ____ I2
