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.
3) Writing the chemical equations.
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 reactions:
1) Na3PO4 + 3 KOH à 3 NaOH + K3PO4 _________________________
2) MgCl2 + Li2CO3 à MgCO3 + 2 LiCl _________________________
3) C6H12 + 9 O2 à 6 CO2 + 6 H2O _________________________
4) Pb + FeSO4 à PbSO4 + Fe _________________________
5) CaCO3 à CaO + CO2 _________________________
6) P4 + 3 O2 à 2 P2O3 _________________________
7) 2 RbNO3 + BeF2 à Be(NO3)2 + 2 RbF ________________________
8) 2 AgNO3 + Cu à Cu(NO3)2 + 2 Ag ________________________
9) C3H6O + 4 O2 à 3 CO2 + 3 H2O _________________________
10) 2 C5H5 + Fe à Fe(C5H5)2 _________________________
Section 2: Practicing equation balancing
Before you can write 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 à __ H2O + __ CO2
2) __ NaI + __ Pb(SO4)2 à __ PbI4 + __ Na2SO4
3) __ NH3 + __ O2 à__ NO + __ H2O
4) __ Fe(OH)3 à __ Fe2O3 + __ H2O
5) __ HNO3 + __ Mg(OH)2 à __H2O + __ Mg(NO3)2
6) __ H3PO4 + __ NaBr à __ HBr + __ Na3PO4
Section 3: Predicting the products of chemical reactions
Predict the products of the following reactions:
1) __ Ag + __CuSO4 à
Type:___________________________
2) __ NaI + __ CaCl2 à
Type:___________________________
3) __ HNO3 + __ Mn(OH)2 à
Type:___________________________
5) __ AgNO2 + __ BaSO4 à
Type:___________________________
