Skill Practice 3 Name: Date: Hour: 1. Explain why compounds are always homogeneous, but mixtures can be either homogeneous or heterogeneous. With a compound (such as salt or sugar), one microscopic portion has the same composition as another microscopic portion. 215 g 333.6g ( theoretical yield. Divide 2 C4H10 + 13 O2 ( 8 CO2 + 10 H2O. 58 g/mol 18 g/mol multiply. 3.71 mol 18.53 mol. Percent yield = (295.3g) ÷ (333.6) ∙ 100 = 88.5% Consider the double replacement reaction of excess sodium chloride with 203.9g of silver nitrate. If you are able to produce 150.4g of silver chloride what was your percent yield? 100% Yield theoretica l yield actual yield% Yield 3. Use the balanced equation to find out how many liters of sulfur dioxide are actually produced at STP if 1.5 x 1027 molecules of zinc sulfide are reacted with excess oxygen and the percent yield is 75%. 2 ZnS(s) + 3 O 2 (g) 2 ZnO(s) + 2 SO 2 (g).

1. Given the following equation:

a) Balance the equation.

_____ K₂PtCl₄ + __2___ NH₃g _____ Pt(NH₃)₂Cl₂ + __2___ KCl

Percent Yield Skill Practice 34 Chapter

b) Determine the theoretical yield of KCl if you start with 34.5 grams of NH₃. 151 g KCl

c) Starting with 34.5 g of NH₃, and you isolate 76.4 g of Pt(NH₃)₂Cl₂, what is the percent yield? Theoretical yield = 303.9 g Pt(NH₃)₂Cl₂; 25.14 % yield

2. Given the following equation:

Percent Yield Skill Practice 34 B

H₃PO₄ + 3 KOH g K₃PO₄ + 3 H₂O

Practice Percent Yield Skill Practice 34

If 49.0 g of H₃PO₄ is reacted with excess KOH, determine the percent yield of K₃PO₄ if you isolate 49.0 g of K₃PO₄. Theoretical yield = 106.1 g K₃PO₄; 46.17 % yield

3. Given the following equation:

Al₂(SO₃)₃ + 6 NaOH g 3 Na₂SO₃ + 2 Al(OH)₃

If you start with 389.4 g of Al₂(SO₃)₃ and you isolate 212.4 g of Na₂SO₃, what is your percent yield for this reaction? Theoretical yield = 500.6 g Na₂SO₃; 42.43 % yield

4. Given the following equation:

Al(OH)₃ (s) + 3 HCl (aq) g AlCl₃ (aq) + 3 H₂O (l)

Percent Yield Skill Practice 34 1

If you start with 50.3 g of Al(OH)₃ and you isolate 39.5 g of AlCl₃, what is the percent yield? Theoretical yield = 86.0 g AlCl₃; 45.93 % yield
