Homework Help: chemisrty

Posted by Ethan on Monday, November 16, 2009 at 12:28pm.

I have no idea how to do this activity..can someone please help!?

In this activity you will investigate how chemical reactions are limited by the amount of reactants present. You will be using paper clips to represent atoms. You can describe the quantities of reactants and products in a chemical reaction from a balanced chemical equation. You will investigate how the quantities of each reactant influences the amount of product formed. Remember limiting reagent limits or determines the amount of product that can be formed in a reaction. The excess reagent will remain unreacted.
When you remove 15 molecules from the paper bag, you should have between 5 and 10 metal paper clips molecules (M2) and the remainder, colored paper clips (15-n M2). If you do not, do it again so that you do.

(There are 5 questions to the activity and if anyone can help me with this I will really appreciate it because I have no clue)

1. List the number of each type of reactant molecule that you removed from the bag.
2. How many molecules of the product did you form?
3. Which reactant molecule did you run out of first?
4. How many molecules of each reactant remained at the completion of the reaction?
5. Repeat the experiment and compare the results.
