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

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
