1. REACTION TYPES Valerie Linacre & Kareena Klahr ** Left click mouse to view slides

2. Types of Reactions  Single Displacement  Double Displacement  Combination  Combustion  Decomposition

3. Single Displacement  A chemical reaction whereby a free element substitutes for another element in a compound.  In this type of reaction, displacement normally occurs when A is more reactive than B  Generic Formula:  A + BX AX + B  A + BX B + AX  A + BX X + AB (or BA)

4. Single Displacement

5.  Examples:  Mg + 2HCl MgCl 2 + H 2  Cu + AgNO 3 Ag + CuNO 3  Cl 2 + CH 4 4H + CCl 2

6. Double Displacement  When two or more reactants form one product which is either a solid compound or a molecular compound  Generic Formula:  AX + BY AY + BX

7. Double Displacement

8.  Examples:  Ag NO 3 + NaCl AgCl + NaNO 3  Pb(NO 3 ) 2 + 2 KI PbI 2 + 2 KNO 3

9. Combination  A chemical reaction where one compound is formed from two elements and/or compounds  Generic Formula:  A + B AB

10. Combination

11. Combination  Examples:  8 Fe + S 8 8 FeS  CaO + CO 2 CaCO 3

12. Decomposition  A chemical reaction where one compound decomposes into two or more elements and/or compounds  Generic Formula:  AB A + B

13. Decomposition  Examples:  2H 2 O O 2 + 2H 2 O  H 2 CO 3 H 2 O + C0 2

14. Combustion  A chemical reaction of an element or compound with oxygen  Combustion normally is with a flame  Generic Formula:  Carbon-Hydrogen Compound Carbon Dioxide + Water

15. Combustion  When carbon-hydrogen compounds go through combustion with an excess of oxygen, the products are carbon dioxide and water  When these compounds go through combustion with less oxygen, the products can also be carbon monoxide

16. Combustion  Example:  With an excess of oxygen…  CH 4 + 2O 2 CO 2 + 2H 2 O

17. Combustion  Example:  With less oxygen needed…  2C 8 H 18 + 17O 2 16CO + 18H 2 O
