Predicting Products
Instructions: 1. Predict the products for these reaction and then 2. Balance the equations. 1) Synthesis (Combination) of Ionic Compounds: 2) Decomposition: Al2O3 a. 2 KCl à __________ 2 K + __________ Cl2
a. 4 Al + 3 O2 à _2 _________ NaF b. Ca3N2 à __________ 3 Ca + _________ N2
b. 2 Na + F2 à _2 _________ 2) Dissociation: K+
Cl-­‐
Ba+2
2 Cl-­‐
a. KCl à ___________ + __________ b. BaCl2 à __________ + ________ 3) Single Replacement: Use the Activity Series to determine a replacement will occur. NR
a. 2 Fe + Al2O3 à __________ + __________ Br2 + ___________ 2 KCl
b. 2 KBr + Cl2 à __________ I2
2 KBr
c. 2 KI + Br2 à __________ + 2 Kl H2 + _Pb(NO
3)2
d. Pb + 2 HNO3 à __________ _________ 4) Combustion: Identify the combustion reactions by circling them. Already balanced. a. 2 Ag + Na2O à 2 Na + Ag2O d. CH4 + 2 O2 à CO2 + 2 H2O b. 2 Na + O2 à Na2O e. 2 Na + Pb(NO3)2 à Pb + 2 NaNO3 c. 2 C3H7OH + 9 O2 à 6 CO2 + 8 H2O f. C3H8 + 5 O2 à 3 CO2 + 4 H2O 5) Double Replacement: Already balanced. Just circle the ppts. Use the SOLUBILITY RULES to determine which product is the precipitate (ppt). a. AgNO3 + NaBr à AgBr + NaNO3 b. CaCl2 + K2CO3 à 2KCl + CaCO3 c. 3 Pb(NO3)2 + 2 Na3PO4 à Pb3(PO4)2 + 6 NaNO3 d. NaCl + KNO3 à KCl + NaNO3 no ppt (NR) e. 3 (NH4)2S + 2 Al(NO3)3 à Al2S3 + 6 NH4NO3 f. BaCl2 + Na2SO4 à BaSO4 + 2 NaCl 6) Predict the products for the following reactions and balance the equation, just as you see on the front side. This time the six different types of reactions are mixed, so Hirst, determine the type of reaction to help you predict the products! Type of Reaction met SR
