1. If you decompose 500.0 g of sodium chloride, how many grams of sodium are produced?
2. If you combust 250.0 g of nonane, how many liters of oxygen are consumed to make the reaction go to completion? Assume STP.
3. If you react 450.0 g of copper (II) nitrate with excess calcium, how much copper (II) is produced.
4. If you react 400.0 g of ammonium dichromate with excess mercury (I) phosphate, many grams of the mercury containing compound will be formed?
5. The equation for photosynthesis is: carbon dioxide + water (with light) = oxygen and glucose (C6H12O6). If 100.0 g of water reacts with excess carbon dioxide, how many liters of oxygen will be produced? Assume STP.
6. Using the equation above, what is the minimum number of grams of carbon dioxide that you would need to start with in order to get 1000.0 g of glucose?

1. If you start with 5.0 x 1043 molecules of cyclopentane, how many grams of carbon dioxide are produced in this combustion reaction?
2. If you start with 3.32 moles of potassium dichromate and you react it with excess lead (IV) iodide, how many moles of the lead compound are produced?
3. If you react 37.0 g of calcium chloride with magnesium chromate, how many grams of each product are produced?
4. Consider the following question: If you have 47.0 atoms of aluminum sulfate, how many grams of aluminum sulfate do you have? Explain why this is not a stoichiometry problem. Which produces more sodium, the decomposition of 1000.0 grams of sodium chloride or the single displacement reaction of 1000.0 grams of sodium sulfate with excess lead (IV)?
5. You begin with 45.76 g of sodium chloride and an unlimited supply of lead (III) oxide. If a reaction does occur, how many grams of the lead (III) chloride are produced? Oh yeah, lead (III) oxide and salt don't react with one another. This is a challenging problem; keep at it!
