We are planning to add several new products to our products line. Since our chemist has recently been involved in a traffic accident and will not be available for several weeks, we need to hire your organization to conduct the pre-production research and let us know the quantity of reactants we need to order.

We plan to produce one metric ton per month of the following compounds:

BaCO₃, CaCO₃ and SrCO₃. We assume that the best reactants would be BaCl₂:2H₂0, CaCl₂: 2H₂0, Na₂C0₃, and Sr(N0₃)₂, all of which are readily available through our suppliers.

We need you to verify that these are the appropriate reactants for our desired products. Further, we need to know the quantities of each we need to order for our production line. If possible, could you suggest any other reactants which might yield our needed products.

We are looking forward to receiving your report in two weeks.


Sincerely yours,


Charles Overhoff
Manager
Order Department

PART II: InterLab Memo

As you can see from the attached letter, our group was asked to conduct pre-production research involving stoichiometry.

I would like the class as a whole to brainstorm on the following three ideas:

1) how can we best produce the products required,

2) how can we use stoichiometry to calculate reactant and product quantities, and

3) how could we best perform the experiments. Then each group will select one of the needed products and conduct the appropriate theoretical and practical research.

Each work group will submit a report (due two weeks from today) which should include the following sections:

1. Initial Working Hypothesis or Objectives.

2. Initial Working Plan.

3. Your Data.
---Please show ALL measurements and calculations of your group's share of the project.

4. Analysis of the Data
---Does the data support your hypothesis? Why? Why not?

5. Further Steps Taken.
---Did you do anything beyond your initial working plan? Why? What did you find?

6. A Letter of Response.
---Each group should submit a response directed to the client outlining what you did, what you found and how this addresses the questions proposed by the client.
