1 Student Learning Map Left Side Concept: Chemical Reactions
LEQ1: How are chemical reactions classified into different categories based on types of reactants and products? LEQ2: Why are coefficients added to chemical equations?

2 Vocabulary Synthesis reaction Decomposition Reaction
Single Replacement Reaction Double Replacement Reaction Combustion Reaction Reactant Product Law of Conservation of Mass Coefficient

3 Student Learning map Right Side Concept: Acids and Bases
LEQ1: How are acids and bases differentiated? LEQ2: No LEQ2

4 Vocabulary Acid Base pH Neutralization Reaction

5 Brainpop Take notes on your graphic organizer about each topic as you watch brainpop

6 Types of Chemical Reactions
Synthesis Decomposition Single Replacement Double Replacement

7 Chemical Equations Show the reactants and products of a chemical reaction (when two or more chemicals create new substances) Reactants The substances that will undergo a chemical change Found to the left of the yield sign (arrow) Products The substances that are produced (made) during a chemical change Found to the right of the yield sign (arrow)

8 Reading a Chemical Equation
Plus or add Yields NaOH(aq) + HCl(aq)  NaCl(s) + HOH(l) Reactants Products

9 Chemical Equation Symbols
Basic: + plus  yields States of matter (subscripts): (aq) aqueous (dissolved in water) (s) solid (l) liquid (g) gas

10 Synthesis Reaction Two or more individual chemicals combine to make one new chemical What to look for: two or more reactants and only one product Examples: A + B  C Na + Cl  NaCl O2 + H2O  H2O2

11 Identify the Synthesis Reactions
2SO2 + O2  2SO3 Al2(SO4)3 + 3Ca(OH)2  2Al(OH)3 + 3CaSO4 2C2H2 + 5O2  4CO2 + 2H2O Mg + 2AgNO3  Mg(NO3)2 + 2Ag 3Ba(NO3)2 + 2H3PO4  Ba3(PO4)2 + 6HNO3 Mg(ClO3)2  MgCl2 + 3O2 2Be + O2  2BeO 2Al + 3CuSO4  Al2(SO4)3 + 3Cu 2PbO2  2PbO + O2 2C2H6 + 7O2  4CO2 + 6H2O

12 Decomposition Reaction
One chemical breaks down into two or more new chemicals What to look for: one reactant and two or more products Examples: AB  A + B H2O2  H2O + O2 LiBr  Li + Br2

13 Identify the Decomposition Reactions
2SO2 + O2  2SO3 Al2(SO4)3 + 3Ca(OH)2  2Al(OH)3 + 3CaSO4 2C2H2 + 5O2  4CO2 + 2H2O Mg + 2AgNO3  Mg(NO3)2 + 2Ag 3Ba(NO3)2 + 2H3PO4  Ba3(PO4)2 + 6HNO3 Mg(ClO3)2  MgCl2 + 3O2 2Be + O2  2BeO 2Al + 3CuSO4  Al2(SO4)3 + 3Cu 2PbO2  2PbO + O2 2C2H6 + 7O2  4CO2 + 6H2O

14 Single Replacement Reaction
One lone element replaces another element in a compound, creating a new compound and a new lone element What to look for: one element and one compound for both the reactants and the products Examples: AB + C  AC + B Al + HCl  AlCl3 + H2 AgNO3 + Cu  Cu(NO3)2 + Ag

15 Identify the Single Replacement Reactions
2SO2 + O2  2SO3 Al2(SO4)3 + 3Ca(OH)2  2Al(OH)3 + 3CaSO4 2C2H2 + 5O2  4CO2 + 2H2O Mg + 2AgNO3  Mg(NO3)2 + 2Ag 3Ba(NO3)2 + 2H3PO4  Ba3(PO4)2 + 6HNO3 Mg(ClO3)2  MgCl2 + 3O2 2Be + O2  2BeO 2Al + 3CuSO4  Al2(SO4)3 + 3Cu 2PbO2  2PbO + O2 2C2H6 + 7O2  4CO2 + 6H2O

16 Double Replacement Reaction
Two compounds combine and exchange ions to produce two new compounds What to look for: two compounds for both the reactants and the products Examples: AB + CD  AD + CB NaOH + HCl  NaCl + HOH AgNO3 + KBr  AgBr + KNO3

17 Identify the Double Replacement Reactions
2SO2 + O2  2SO3 Al2(SO4)3 + 3Ca(OH)2  2Al(OH)3 + 3CaSO4 2C2H2 + 5O2  4CO2 + 2H2O Mg + 2AgNO3  Mg(NO3)2 + 2Ag 3Ba(NO3)2 + 2H3PO4  Ba3(PO4)2 + 6HNO3 Mg(ClO3)2  MgCl2 + 3O2 2Be + O2  2BeO 2Al + 3CuSO4  Al2(SO4)3 + 3Cu 2PbO2  2PbO + O2 2C2H6 + 7O2  4CO2 + 6H2O

18 Combustion Reaction A hydrocarbon and oxygen combine with a heat source to produce dihydrogen monoxide and carbon dioxide. A hydrocarbon is a compound composed of only hydrogen and carbon. Examples: CH4 + O2  CO2 + H2O C2H6 + O2  CO2 + H2O

19 Identify the Combustion Reactions
2SO2 + O2  2SO3 Al2(SO4)3 + 3Ca(OH)2  2Al(OH)3 + 3CaSO4 2C2H2 + 5O2  4CO2 + 2H2O Mg + 2AgNO3  Mg(NO3)2 + 2Ag 3Ba(NO3)2 + 2H3PO4  Ba3(PO4)2 + 6HNO3 Mg(ClO3)2  MgCl2 + 3O2 2Be + O2  2BeO 2Al + 3CuSO4  Al2(SO4)3 + 3Cu 2PbO2  2PbO + O2 2C2H6 + 7O2  4CO2 + 6H2O

20 Identify the type of Reaction
LiBr + NaCl  LiCl + NaBr Li + NaCl  LiCl + Na O2 + CH4  H2O + CO2 Li + Cl2  2 LiCl 2 LiCl  Li + Cl2 Double Replacement Single Replacement Combustion Synthesis Decomposition
