Honors Chemistry Chapter 12 Worksheet 1 Name ______

1. If 50.0 grams of Zinc are reacted with 50.0 grams of Hydrogen Chloride (dissolved in water, of course), how many grams of ionic product will result? If 70.0 g of the product are actually produced, what is the % yield?

2. How many grams of product are created from the synthesis of Hydrogen and Chlorine gases if 10.0 grams of each gas are reacted to produce a % yield of 82.5%?

3. How many grams of sodium chloride can be produced from 4.80 grams of sodium with an excess of calcium chloride?

4. How many grams of iron can be produced from 23.94 grams of iron (III) oxide and an excess of carbon if the % yield is 91.25%? (Hint - the other product of this reaction is also a product of a combustion reaction)

5. a) If a really large quantity of aqueous sodium chloride solution is reacted with 1.00 Kg of lead (II) nitrate, how many grams of sodium chloride will be used in the reaction?

b) If the solution originally held a total of 3530 grams of salt, how much will be left over at the end of the reaction?

6. If a decomposition reaction produces a 75.0% yield for the oxygen by mass (128.0 grams were produced), How many moles of Mercury (I) oxide were decomposed?

7. What is the actual yield for a reaction where 765.0 grams of carbon monoxide are created, but the percent yield is only 32.0 %?

8. If sulfur dioxide is reacted with oxygen under the right conditions, sulfur trioxide can be produced. This reaction generally has a 85.0% yield. If 356.8 grams of sulfur trioxide are actually recovered in the experiment, how many liters of both reactants did you start with?
