1. Limiting reactant

2. Ever notice how hot dogs are sold in packages of 10 while the buns come in packages of 8?? The buns limit the hot dog production to 8! In chemistry, we would call the buns the LIMITING REACTANT. Our equation would look like this:

4. Which is the limiting reactant, red or green? http://www.mhhe.com/physsci/chemistry/chang7/esp/folder_structure/cr/m2/s3/

5. If red is “A” and green is “B”, write the balanced chemical equation that represents the reaction? http://www.mhhe.com/physsci/chemistry/chang7/esp/folder_structure/cr/m2/s3/

8. When looking at a particle diagram, how can you determine which reactant is the limiting reactant?

10. Limiting reactant – Any reactant that is used up first in a chemical reaction; it determines the amount of product (theoretical yield) that can be formed in the reaction. Excess reactant – A reactant present in a quantity that is more than sufficient to react with a limiting reactant; any reactant the remains after the limiting reactant is used up in a chemical reaction.

11. I have unlimited amounts of everything except butter. I only have 4 sticks of butter. How many dozen cookies can I make?

12. I have: 9 cups of flour A box of baking soda A carton of salt 10 sticks of butter A 5 lb. bag of sugar A 2 lb. bag of light brown sugar A bottle of vanilla extract 4 eggs 6 bags of chocolate chips How many dozen cookies can I make? What will I run out of first? How much extra butter will I have?

13. When looking at a recipe, how can you determine which ingredient will limit your amount of product?

14. Limiting Reactant CalculationsLimiting Reactant Calculations (9:03) Calculate the amount of product (if more than one product, pick one) that can be produced by the available amount of each reactant. The reactant that gives you LESS product is the LIMITING reactant.

15. Limiting Reactant Calculations John has 100.0 grams of each reactant available. Determine which reactant is the limiting reactant. How much aluminum is produced? 3 Ca + 2 AlBr 3  3 CaBr 2 + 2 Al

16. Limiting Reactant Practice 39.5 grams of zinc are reacted with 42.6 grams of hydrochloric acid. Which is the limiting reactant? How much hydrogen gas is produced? Zn + 2HCl  ZnCl 2 + H 2
