Single Replacement, Double Replacement and Combustion Reactions

2. Li Rb K Ba Sr Ca Na Mg Al Mn Zn Cr Fe Cd Co Ni Sn Pb
 H2  Sb Bi Cu Hg Ag Pt Au
Single Replacement: One element replaces a similar element in a compound. **Rxn. May Not Occur!
Metals replace Metals & Non-metals replace non-metals ***based on the activity series on page 333.
The Higher element replaces the Lower element. If the Element is lower, it will NOT react.
A + BC  AC + B

3. Single Replacement of Metals:
Al + Fe(NO3)2 
Ag + CuCl2 
Single Replacement of Hydrogen:
Mg + HCl 
Na + HOH 
Cu + HCl 
Single Replacement of Halogens:
Cl2 + KI 
Br2 + MgCl2 

4. Which of the following will not occur….
Ba + Cu(NO3)2 
Mg + Cu(NO3)2 
Ag + Cu(NO3)2
Fe + Cu(NO3)2 

5. Which of the following will not occur….
Ba + Mg(NO3)2 
Fe + Mg(NO3)2 
Ca + Mg(NO3)2
Na + Mg(NO3)2 

6. Which of the following will not occur….
Cl MgF2 
Br2 + CuI2 
Cl2 + KBr 
F AlCl3 

7. Combustion: “ burning” in the presence of Oxygen
CH4 + O2 
C2H6 + O2 
C4H8 + O2 

8. May form a ppt., a gas, or liquid water.
Double Replacement: Ions of two compounds exchange places. (Partner Swap)
AB + CD  AD + CB
May form a ppt., a gas, or liquid water.
Example:
BaCl2 + LiNO3 
HCl + Ca(OH)2 
Pb(NO3)2 + Al2(SO4)3 

9. ClPb + KNO3 PbCl2 + KNO3 KCl + Pb(NO3)2 NO3K + PbCl2
When Potassium chloride reacts with Lead II nitrate which product will form?
ClPb + KNO3
PbCl2 + KNO3
KCl + Pb(NO3)2
NO3K + PbCl2
