There are FIVE main types of chemical reactions • Synthesis Reaction • Decomposition Reaction • Single Displacement Reaction • Double Displacement Reaction • Combustion Reaction
Synthesis Reactions Two reactants combine to form ONE product • “Addition” reaction General format: A + B AB EX: 4 Al + 3 O2 2 Al2O3 2 Na + Cl2 2 NaCl
Decomposition Reactions ONE reactant breaks down into two or more products • Opposite of synthesis General Format: AB A + B EX: 2 KClO3 2 KCl + 3 O2 2 MgO 2 Mg + O2
Single Displacement Reactions One ELEMENT replaces another element in a compound General Format: A + BCAC + B EX: Ca + 2 Ag(NO3) 2 Ag + Ca(NO3)2 Fe + CuCl2FeCl2 + Cu
Double Displacement Reactions TWO compounds produce two NEW COMPOUNDS • The positive ions replace each other General Format: AB + CDAD + CB EX: NaCl + KBrNaBr + KCl 2 K(OH) +Pb(NO3)22 K(NO3)+Pb(OH)2 H3(PO4) +3K(OH)K3(PO4) +3 H2O
Combustion Reactions A HYDROCARBON (contains hydrogen and carbon and sometimes oxygen) combines with OXYGEN to form CARBON DIOXIDE and WATER General Format: CXHY + O2CO2 + H2O EX: CH4 + 2 O2CO2 + 2 H2O
Your Turn!! synthesis 2 Ca + O2 2 CaO Br2 + 2 LiI 2 LiBr + I2 2 Al + 3 Fe(NO3)2 2 Al(NO3)3 + 3 Fe MgO + HCl MgCl2 + H2O 2 C4H10 + 13 O2 8 CO2 + 10 H2O single displacement single displacement double displacement combustion
Your Turn!! decomposition 2 H2O2 2 H2O + O2 2 (NH4)3(PO4) + 3 Sr(OH)2 Sr3(PO4)2 + 6 (NH4)(OH) H2(SO4) + 2 Na(OH) Na2(SO4) + 2 H2O Zn + 2 Ag(NO3) Zn(NO3)2 + 2 Ag Cu(NO3) + KCl K(NO3) + CuCl double displacement double displacement single displacement double displacement
