  1. Objective: To identify the five types of chemical equations.

  2. Types of Chemical Reactions

  3. What are the Types of Chemical Reactions? • Synthesis Reaction • Decomposition Reaction • Single Replacement Reaction • Double Replacement Reaction • Combustion Reaction

  4. Synthesis Reactions (Combination Reactions) • A chemical change in which 2 or more substances form a single new substance. • Key = 1 product • General Equation: A + B  C

  5. Examples H2 + O2 K + Cl2  Mg + O2  Remember: BrINClHOF!!

  6. Examples H2 + O2 H2O K + Cl2  KCl Mg + O2  MgO Remember: BrINClHOF!!

  7. Decomposition Reactions • A chemical change in which a single compound breaks down into two or more simpler substances. • Opposite of synthesis reaction. • Key = 1 reactant • General Equation: A  B + C

  8. Examples H2O  KCl  H2O2 

  9. Examples H2O  H2 + O2 KCl  K + Cl2 H2O2  H2 + H2O

  10. Single Replacement Reactions • A chemical change in which one element replaces a second element in a compound. • A cation must replace a cation, and an anion must replace an anion. • To determine if the reaction occurs, you must use the activity series. • Key = 1 element & 1 compound as reactants • General Equation: A + BC  B + AC or A + BC  C + AB

  11. Examples Cu + AgNO3 K + H2SO4  Na + LiCl  F2 + Na Cl 

  12. Examples Cu + AgNO3 CuNO3 + Ag K + H2SO4  K2SO4 + H2 Na + LiCl  No Reaction F2 + Na Cl  NaF + Cl2

  13. Double Replacement Reactions • A chemical change involving the exchange of cations between two compounds. • Takes place in aqueous solution and must produce a precipitate, a gas, or a covalent compounds such as water.

  14. To determine if the reaction occurs, you must use the solubility rules. • Key = 2 compounds as reactants • General Equation: AB + CD  AD + CB

  15. Examples CaSO4 + NaCl  KI + Pb(NO3) 2  BaBr2 + KCl 

  16. Examples CaSO4 + NaCl  No Reaction KI + Pb(NO3) 2  PbI2 + KNO3 BaBr2 + KCl  No Reaction

  17. Combustion Reaction • A chemical change in which an element or compound reacts with oxygen producing energy in the form of heat or light. • A hydrocarbon and oxygen are always the reactants. • Carbon dioxide and water are always products. • General Equation: CxHy + O2 CO2 + H2O

  18. Examples CH4 + 2O2 CO2 + 2H2O
