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?

¡°What?s 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 cc?s should the nurse give to the child for each dose?

A.

B.

C.

D.

6.15 cc.

8.13 cc.

4.06 cc.

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 child?s 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 ¨C 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¡±
