1. Types of Chemical Reactions

2. Synthesis Reactions Fe + O2O2 Fe 2 O 3 4 3 2 A + B AB

3. Decomposition Reactions H2OH2O electricity H2H2 + O2O2 22 ABAB A + B

4. Single Displacement Reactions Mg + Ag + Mg(NO 3 ) 2 2 2 NO 3

5. A + BACAC + B Remember that in deciding which element is replaced (displaced),we use the general rule that metal replacing metal and non-metal replacing non-metal. Br 2 +CaCaBr 2 + I2I2 CB I2I2 I2I2

6. Double Displacement Reactions Pb + KIKI PbI 2 KNO 3 + 22 (NO 3 ) 2

7. Combustion Reactions H2H2 + O2O2 H2OH2O2 2 C + O2O2 CO 2

8. Combustion of Ethane (C 2 H 6 ) Complete combustion… Only two products in the complete combustion of a hydrocarbon. C2H6C2H6 + O2O2 CO 2 + H2OH2O6 472

9. Incomplete Combustion C 24 H 50 + 26O 2 → 5C + 8CO 2 + 25H 2 O + 11CO Four products result in the incomplete combustion of a hydrocarbon.

10. General Formulas Synthesis A + B  AB Decomposition AB  A + B Single Displacement A + BC  B + AC Double Displacement AB + CD  AD + CB

11. More General Formulas Complete combustion of hydrogen H 2 + O 2  H 2 O Complete combustion of carbon C + O 2  CO 2 Complete combustion of a hydrocarbon C x H y + O 2  CO 2 + H 2 O Incomplete combustion of a hydrocarbon C x H y + O 2  C + CO + CO 2 + H 2 O
