Monday 4/2/12 Get out your chemical reaction notes you have been taking and your balancing equations practice sheet. Try to balance the equations on the back.

C. Balancing Example 2 Al + CuCl2  Cu + AlCl3 Al Cu Cl 3 3 2 2  1 1 Aluminum and copper(II) chloride react to form copper and aluminum chloride. 2 Al + CuCl2  Cu + AlCl3 Al Cu Cl 3 3 2 2  1 1 2 3  2  6 3  6   3

__NaNO3 + __PbO __Pb(NO3)2 +__Na2O

__AgI + __Fe2(CO3)3__ FeI3+__Ag2CO3

__C2H4O2+__O2__CO2+__H2O

__ZnSO4+__Li2CO3__ZnCO3+__Li2SO4

__V2O5+__CaS__CaO+__V2S5

__Mn(NO2)2+__BeCl2__Be(NO2)2 +__MnCl2

__AgBr+__GaPO4__Ag3PO4+__GaBr3

__H2SO4+__B(OH)3__B2(SO4)3+__H2O

__S8+__O2__SO2

__Fe+__AgNO3__Fe(NO3)2+__Ag

Wednesday 4/18/12 1. Make sure you turned in your rxn rate vocab, 11.2 vocab, & 11.2 Guided reading to class tray. 2. Get out paper for notes and answer the following question: What are the different types of reac tions?

Types of Chemical Reactions

A. Synthesis the combination of 2 or more substances to form a compound only one product A + B  AB

A. Synthesis H2(g) + Cl2(g)  2 HCl(g)

CH4(g) + 2O2(g)  CO2(g) + 2H2O(g) B. Combustion the burning of any substance in O2 to produce heat A + O2  B CH4(g) + 2O2(g)  CO2(g) + 2H2O(g) EX: Burning of natural gas, wood and gasoline

AB  A + B C. Decomposition a compound breaks down into 2 or more simpler substances only one reactant AB  A + B

C. Decomposition 2 H2O(l)  2 H2(g) + O2(g)

A + BC  B + AC D. Single Replacement one element replaces another in a compound metal replaces metal (+) nonmetal replaces nonmetal (-) Halogens are replaced by a more reactive halogen A + BC  B + AC

Cu(s) + 2AgNO3(aq)  Cu(NO3)2(aq) + 2Ag(s) D. Single Replacement Cu(s) + 2AgNO3(aq)  Cu(NO3)2(aq) + 2Ag(s)

AB + CD  AD + CB E. Double Replacement ions in two compounds “change partners” cation of one compound combines with anion of the other AB + CD  AD + CB

Pb(NO3)2(aq) + K2CrO4(aq)  PbCrO4(s) + 2KNO3(aq) E. Double Replacement Pb(NO3)2(aq) + K2CrO4(aq)  PbCrO4(s) + 2KNO3(aq)
