A Voyage through Equations

A Voyage through Equations After working on this worksheet, you should be able to do the following: 1) Given an equation, you should be able to tell what kind of reaction it is. 2) Predict the products of a reaction when given the reactants. Section 1: Identify the type of reaction For the following reactions, indicate whether the following are examples of synthesis, decomposition, combustion, single displacement, double displacement, or acid-base reactions: 1) Na3PO4 + 3 KOH  3 NaOH + K3PO4 _________________________ 2) MgCl2 + Li2CO3  MgCO3 + 2 LiCl _________________________ 3) C6H12 + 9 O2  6 CO2 + 6 H2O _________________________ 4) Pb + FeSO4  PbSO4 + Fe _________________________ 5) CaCO3  CaO + CO2 _________________________ 6) P4 + 3 O2  2 P2O3 _________________________ 7) 2 RbNO3 + BeF2  Be(NO3)2 + 2 RbF ________________________ 8) 2 AgNO3 + Cu  Cu(NO3)2 + 2 Ag ________________________ 9) C3H6O + 4 O2  3 CO2 + 3 H2O _________________________ 10) 2 C5H5 + Fe  Fe(C5H5)2 _________________________ 11) SeCl6 + O2  SeO2 + 3Cl2 _________________________ 12) 2 MgI2 + Mn(SO3)2  2 MgSO3 + MnI4 _________________________ 13) O3  O. + O2 _________________________ 14) 2 NO2  2 O2 + N2_________________________ Section 2: Practicing equation balancing Before you can write a balanced equation for a problem which asks you to predict the products of a reaction, you need to know how to balance an equation. Because some of you may not fully remember how to balance an equation, here are some practice problems: 1) __ C6H6 + __ O2  __ H2O + __ CO2 2) __ NaI + __ Pb(SO4)2  __ PbI4 + __ Na2SO4 3) __ NH3 + __ O2 __ NO + __ H2O 4) __ Fe(OH)3  __ Fe2O3 + __ H2O 5) __ HNO3 + __ Mg(OH)2  __H2O + __ Mg(NO3)2 6) __ H3PO4 + __ NaBr  __ HBr + __ Na3PO4 7) __ C + __ H2  __ C3H8 8) __ CaO + __ MnI4  __ MnO2 + __ CaI2 9) __ Fe2O3 + __ H2O  __ Fe(OH)3 10) __ C2H2 + __ H2  __ C2H6 11) __ VF5 + __ HI  __ V2I10 + __ HF 12) __ OsO4 + __ PtCl4  __ PtO2 + __ OsCl8 13) __ CF4 + __ Br2  __ CBr4 + __ F2 14) __ Hg2I2 + __ O2  __ Hg2O + __ I2 15) __ Y(NO3)2 + __ GaPO4  __ YPO4 + __ Ga(NO3)2 Section 3: Predicting the products of chemical reactions Predict the products of the following reactions: 1) __ Ag + __CuSO4  Type:___________________________ 2) __ NaI + __ CaCl2  Type:___________________________ 3) __ O2 + __ H2  Type:___________________________ 4) __ HNO3 + __ Mn(OH)2  Type:___________________________ 5) __ AgNO2 + __ BaSO4  Type:___________________________ 6) __ HCN + __ CuSO4  Type:___________________________ 7) __ H2O + __ AgI  Type:___________________________ 8) __ HNO3 + __Fe(OH)3  Type:___________________________ 9) __ LiBr + __ Co(SO3)2  Type:___________________________ 10) __ LiNO3 + __Ag  Type:___________________________ 11) __ N2 + __ O2  Type:___________________________ 12) __ H2CO3  Type:___________________________ 13) __ AlCl3 + __ Cs  Type:___________________________ 14) __ Al(NO3)3 + __ Ga  Type:___________________________ 15) __ H2SO4 + __ NH4OH  Type:___________________________ 16) __ CH3COOH + __ O2  Type:___________________________ 17) __ C4H8 + __ O2  Type:___________________________ 18) __ KCl + __ Mg(OH)2  Type:___________________________ 19) __ Zn + __ Au(NO2)2  Type:___________________________ 20) __ KOH + __ H2SO4  Type:___________________________ 21) __ BaS + __ PtCl2  Type:___________________________ 22) __ Na2O  Type:___________________________
