2. Types of Chemical Reactions
Name four types of chemical reactions, and explain what happens in each one.

3. P4(s) + Cl2(g) PCl3(l) + energy
Balance the equation.
What type of reaction is this? Explain why

4. Single Replacement Reactions
Predict whether each reaction will take place:
Zn + AgNO3  Ag + Zn(NO3)2
Mg + Pb(NO3)2  Pb + Mg(NO3)2
Ag + NaCl  Na + AgCl

5. Double Replacement Reactions
Below are double-replacement reactions. Will a precipitate form? If so, what is the precipitate? Justify your answer.
CaCl2(aq) + Pb(NO3)2(aq)  Ca(NO3)2 (?) + PbCl2(?)
Ba(NO3)2(aq) + Na2SO4(aq)  BaSO4(?) + 2NaNO3(?)

6. Identify the precipitate formed when these following compounds are mixed:
CaCl2 + Pb(NO3)2 
Al2(SO4)3 + NH4OH 

7. Net Ionic Equations Write a balanced net ionic equation for each:
Na3PO4(aq) + FeCl3(aq)  NaCl(aq) + FePO4(s)
(NH4)2S(aq) + Co(NO3)2(aq)  CoS(s) + NH4NO3(aq)

8. Stoichiometry C3H8 + 5O2  4H2O + 3CO2
How many moles of CO2 are produced when 3 moles of C3H8 completely react with O2?
How many moles of H2O are produced when 2.5 moles of O2 completely react with C3H8?
How many moles of O2 are required to produce 6 moles of H2O?
How many moles are C3H8 are required to completely react with 12.5 moles of O2?

9. N2(g) + 3H2(g)  2NH3(g)
How many moles of NH3 are produced when 4.5 moles of H2 react with nitrogen?
How many moles of N2 are required to produce 8 moles of NH3?

10. The kinetic molecular theory states that all particles of an ideal gas are:
Colliding without transferring energy
In random, constant, straight-line motion
Arranged in a regular geometric pattern
Separated by small distances relative to their size
