OBJECTIVE

By the next class period, students will be able to:

  • Understand general principles of chemistry.
  • Understand stoichiometry
  • Demonstrate the ability to solve quantitative problems.
  • Recognize the role of chemistry in real world issues.
  • Demonstrate knowledge of common reactions and reaction mechanisms of the elements & compounds.

The objectives will require that students be able to:

  • Solving real world problems using derivatives
  • Find absolute maximum or minimum value of a function f.



THE CHALLENGE

You are hired as the laboratory manager at a major pharmaceutical company. Your first task is to purchase chemicals for the aspirin production line in order to produce 125,000 aspirin bottles per day.

GENERATE IDEAS

  • How much aspirin is in each bottle?
  • What is the total amount of aspirin needed to be produced?
  • What chemicals are used in the production of aspirin?
  • Is any product lost in the production line?


MULTIPLE PERSPECTIVES

Provided by professor at the end of the Generate ideas portion. (You tube presentation, research articles, etc.)


RESEARCH & REVISE

  • Examine typical aspirin daily production
  • Examining typical production line % loss
  • Examine reactions for aspirin production
  • Balancing chemical equations
  • Computing moles of B from mass of B
  • Converting moles of B to moles of A
  • Examine unit conversion factors

GO PUBLIC

  • Homework and exam problems that apply the module concepts to unrelated applications
    • Examples:
      • An automobile engine produces energy by the combustion of gasoline, which is primarily octane, C8H18. Being a concerned citizen for your local carbon footprint you decide to compute the amount of carbon dioxide that is emitted from your car in one year.
      • The compound diborane (B2H6) was at one time considered for use as a rocket fuel. As an engineer you need to know how many grams of liquid oxygen would a rocket have to carry to burn 10 kg of diborane completely?
