[edit | edit source]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?
