1. Types of Reactions

2. 5 Types of Reactions Combustion Synthesis Decomposition
Single Displacement
Double Displacement

3. Combustion
Oxidation reduction of an organic compound where heat is released
Organic compound reacts with oxygen to make carbon dioxide and water
CH4 + 2O2 → CO2 + 2H2O

4. Synthesis Two or more substances react to form a new compound
2 or more reactants and only 1 product
2C + O2 → 2CO
CO2 + H2O → H2CO3

5. Decomposition
Single compound breaks down to form 2 or more simpler compounds
1 reactant more than 1 product
2H2O → 2H2 + O2
CaCO3 → CO2 + CaO

6. Single Displacement
Single element reacts with a compound and takes the place of one of the elements in the compound
Element and a compound form an element and a compound
2Al(s) + 3CuCl2(aq) → 2AlCl3(aq) + 3Cu(s)

7. Double Displacement
Gas, solid precipitate, or a molecular compound forms from the apparent exchange of atoms or ions between two compounds
2 compound make 2 different compounds
2KI(aq) + Pb(NO3)2(aq)→ PbI2(s) + 2KNO3(aq)

9. Try Theses Rxns KClO3(s) → KCl(s) + O2(g) Decomposition
C3H8(g) + 5O2(g) → 3CO2(g) + 4H2O(g)
Combustion
F2(g) + 2NaCl(aq) → 2NaF(aq) + Cl2(g)
Single displacement
2Fe(s) + O2(g) → 2FeO(s)
Synthesis
FeS(s) + 2HCl(aq) → H2S(g) + FeCl2(aq)
Double displacement
