Legend

You will often find specific icons embedded within the notes. These respective symbols alert the student to the following:

Represents a key fact or other piece of information, such as the definitions of an element and a compound.

Represents a useful trick the student will likely find useful, such as an 'EZ' way to convert between grams and moles for a substance

Alerts the student to an important relationship between micro and macro scale properties or phenomena with respect to the material under discussion

* Such material provides a link to interesting (briefly discussed) supplemental material, often beyond the scope of the course syllabus

Why Chemistry?

"Whats my motivation?" Why are you sitting in this class? In other words, why chemistry? Task: Write down as many reasons as you can that explain why you are taking this class:

(We will also justify responses relating to 3rd party requirements during the session)

Professional programs that benefit directly from a background in chemistry 1. Nursing and allied health (pre-pharm., pre-med., pre-dentistry)

Example: Chlorothiazide (Diuril) is ordered b.i.d. for a infant weighing 6.5 kg. It is supplied in elixir form 100 mg/tsp. The recommended dosage for Diuril is 25 mg/kg/day. How many ccs should the nurse give to the child for each dose?

A. 6.15 cc. B. 8.13 cc. C. 4.06 cc. D. 0.81 cc.

2. Engineering (mechanical, civil, chemical, electrical)

Example: Your company decides to import child safety seats manufactured in Asia. Unfortunately, the safety guidelines for the seats are quoted in ,,metric units. The label reads: "Do not exceed a 150 N load" and you must use this information to determine the maximum weight a child must not exceed in order to be protected during a collision at 55 mph. Can you do it? A childs life, not to mention the financial future of your employer, may depend on your ability to solve questions such as this.

3. Everyday / Real life situations

Example: It is time to re-carpet your 12 ft x 24 ft. family room. You visit a few carpet stores and select a brand that costs $ 20.50 per square meter. The sales person quotes you a total price of $749 ? is this price fair, or have you just been taken advantage of?

** We will return to and solve each of these three problems at some point during the course

Discussion: What do all three of the above examples have in common?

Which professions (or professionals) utilize such skills most commonly?

Hint, "I pretend to be one on occasion"
