Chapter 8 Section 2 **Remember H O N C Br I F Types of Chemical Reactions 1) Combination/Synthesis Reaction -two or more substances combine to form a single substance reactants- two elements or two compounds products- always a compound ex- 2K + C 2 2KC ex- SO2+ H2O H2SO3
Try these!! Dont forget to balance!! a) aluminum + oxygen A + O2 A + O2 A 2O3 b) beryllium + oxygen Be + O2 Be + O2 BeO c) strontium + iodine Sr + I2 Sr + I2 SrI2 d) magnesium + nitrogen Mg + N2 Mg + N2 Mg3N2
2) Decomposition Reaction -one compound breaks down or decomposes into two simpler compounds -the reverse of synthesis ex- 2H2O 2H2+ O2 Try these!! a) lead(IV) oxide PbO2 PbO2 Pb + O2 b) hydrogen iodide HI HI H2+ I2
c) hydrogen bromide HBr HBr H2+ Br2 d) sodium chloride NaC NaC Na + C 2
3) Single-Replacement Reactions -one element replaces a second element in a compound ex- 2K + CaO K2O + Ca -whether one metal will replace another metal is determined by reactivity of the metal activity series of metals- lists metals in order of decreasing reactivity **Page 217 -a metal will replace another metal listed below it in the table
ex- Mg + Zn(NO3)2 *is Mg above Zn on the reactivity series? Mg + Zn(NO3)2 Mg(NO3)2+ Zn ex- Mg + Ag2SO4 Mg + Ag2SO4 MgSO4 + Ag ex- Mg + LiNO3 -lithium is above magnesium Mg + LiNO3 no reaction (NR)
-Halogens can replace each other in single- replacement reactions -Reactivity decreases as you go down the halogen group Try These!! a) zinc + hydrogen sulfate Zn + H2SO4 Zn + H2SO4 H2+ ZnSO4 b) chlorine + sodium bromide C 2+ NaBr C 2+ NaBr Br2+ NaC
c) zinc + sodium nitrate Zn + NaNO3 no reaction d) iron(II) + lead(II) nitrate Fe + Pb(NO3)2 Fe + Pb(NO3)2 Pb + Fe(NO3)2 e) chlorine + sodium iodide C 2+ NaI C 2+ NaI I2+ NaC
4) Double-Replacement Reactions -involve an exchange of cations between two reacting compounds ex- BaC 2+ K2CO3 BaCO3+ 2KC ex- FeS + 2HC H2S + FeC 2 Try These!! a) sodium hydroxide + iron(III) nitrate NaOH + Fe(NO3)3 NaOH + Fe(NO3)3 NaNO3+ Fe(OH)3
b) barium nitrate + hydrogen phosphate Ba(NO3)2+ H3PO4 Ba(NO3)2+ H3PO4 Ba3(PO4)2+ HNO3 c) potassium hydroxide+hydrogen phosphate KOH + H3PO4 KOH + H3PO4 K3PO4 + H2O d) hydrogen sulfate + aluminum hydroxide H2SO4 + A (OH)3 H2SO4 + A (OH)3 A 2(SO4)3+ H2O
5) Combustion Reaction -hydrocarbon combined with oxygen to produce carbon dioxide and water ex- C6H6+ O2 CO2+ H2O -to balance: *always begin with a 2 in front of hydrocarbon *when done, if can divide by 2 do so 2C6H6+ 15O2 12CO2+ 6H2O
Try These!! a) C14H26+ O2 2C14H26+ 41O2 28CO2+ 26H2O b) C8H12+ O2 2C8H12+ 22O2 16CO2+ 12H2O C8H12+ 11O2 8CO2+ 6H2O
Summary of Reactions 1) Combination/Synthesis R + S RS 2) Decomposition Reaction RS R + S 3) Single-Replacement Reaction T + RS R + TS 4) Double-Replacement Reaction RS + TU RU + TS 5) Combustion Reaction CxHy+ O2 CO2+ H2O
