1. LiOH + HBr → LiBr + H2O

If you start with 10.0 grams of lithium hydroxide, how many grams of lithium bromide will be produced?

2. C2H4 + 3 O2 → 2 CO2 + 2 H2O

If you start with 45 grams of ethylene (C2H4), how many grams of carbon dioxide will be produced?

3. Mg + 2 NaF → MgF2 + 2 Na

If you start with 5.5 grams of sodium fluoride, how many grams of magnesium fluoride will be produced?

4. 2 HCl + Na2SO4 → 2 NaCl + H2SO4

If you start with 20. grams of hydrochloric acid, how many grams of sulfuric acid will be produced?

5. Balance the equation:

_____ AgNO3 + _____ FeCl3 → _____ AgCl + _____ Fe(NO3)3

6. If I combine 6.60 grams of FeCl3 with an excess of AgNO3, how much AgCl will I form?

3. If 3.40 grams of AgCl are actually formed, what is the percent yield of this reaction?

6. Given the reaction: 2 Al ​(_s) + 3 NH​₄NO​3 _(s) →  3 N​2 _(g) + 6 H​2O​ (l) + Al​2O​3 _(s) (15 points)
   1. How many atoms of Al will react with 132 formula units of NH^{​ ​                  ​                  ​                  ​                  ​                  ​} ​4NO^​ ​3?

​          ​

5. How many molecules of water will be produced by the combustion of 5.00 g of Al?
6. How many grams of Al​2O​3 will be produced by the reaction of 0.150 moles of Al with 0.150 ​ ​

moles of NH​4NO​3? Use an ICE table.​

7. LiOH + KCl → LiCl + KOH

20. I began this reaction with 20.0 grams of lithium hydroxide. What is my theoretical yield of lithium chloride?
21. I actually produced 6.0 grams of lithium chloride. What is my percent yield?

8. Be + 2 HCl → BeCl2 + H2

My theoretical yield of beryllium chloride was 10.7 grams.  If my actual yield was 4.5 grams, what was my percent yield?
