Is there any way I can get out of this class???

WHY CHEMISTRY ?

This class bullshit is Your first in-class chemistry exercise….

Structure Chemist Organic ChemistNut case chemist Can you locate the chemist’s universal obsession…..?

You can’t see molecules directly. You can’t measure molecules directly. You can’t watch how molecules react. Molecules They’re just too damned small.

Chemistry involves imaginative, BUT deeply abstract metaphors for things (molecules) that we can’t know directly.

CHEMISTRY…is a 250 year old discipline that can take apart, put back together, manipulate and transform objects (molecules) which are objects we have no chance to directly see nor directly measure. Thinking Like a Chemist (TLC) is powerful WHY CHEMISTRY ?

Course Website (see also: Course Syllabus) Course Syllabus (See also: Course Website) Zumdahl Hybrid E-text Scientific Calculator CHEM 1114: BASIC STUFF YOU NEED

YOUR FIRST ASSIGNMENTS By Wednesday 2 Sept: Read Course Syllabus (handout in class) Read Fong CV (curriculum vitae) and `A letter from your chemistry 1114 instructor’ Both found under Miscellaneous at course website: Write me a letter (no longer than 1 page). Tell about yourself and why you’re here. Turn the hard copy in during class (do not me!). (3 pts) Start reading text (Zumdahl & Zumdahl 9 th pp. 8-22)

YOUR SECOND ASSIGNMENT: Prefix symbolPrefix namePower of 10 equivalent TTera Ggiga 10 9 Mmega 10 6 kkilo 10 3 ddeci ccenti mmilli  micro nnano ppico By Friday 4 Sept, get this table in your head see also- table 1.2, pg 10

YOUR THIRD ASSIGNMENT: OWL/2 electronic homework 1 By Wednesday 10 September (midnight at the latest)

From COURSE OUTLINE Week dateslecture topics reading 1 8/31-9/4Units, Prefixes, Sig Figs and pp Measurement Concepts: the ground floor Where do we start to get TLC powerful ?

What is water, ugly human ? WHY START WITH UNITS ????? (BORING….)

Fundamental SI (le S ysteme I nternational) Units (see Table 1.1, p. 9) Length (meters, m) Mass (kilograms, kg) time (seconds, s) Temperature (Kelvin, K) Basic biggies to know count of stuff (moles, mol) `mks’`mks’ + Chemistry add-on

Width of a human blood cell: ~ m time for computer to do a single operation: ~ s Nimitz class aircraft carrier weighs: ~ 100,000,000 kg Distance to Sun: ~13,000,000,000 m ….It’s hard to recognize/remember how many the zeroes…. The “problem’ with the MKS system…

Two ways to keep track of the zeroes and the decimal place: scientific notation Prefixes (see table 1.2, p. 10)

Example:Width of a human blood cell in scientific notation m Review of scientific notation: 6 bunny hops to right starting from decimal to form a number (2) which is between 1 and 9…. aka: Bunny hop arithmetic m= decimal scientific notation 2 *10 -6 m

time for computer to do a single operation: ~ s Nimitz class aircraft carrier weighs: ~ 100,000,000 kg Distance to Sun: ~13,000,000,000 m In-class board practice converting decimal to scientific notation…count with me ! 3*10 -9 s 1*10 +9 kg 1.3* m

Prefixes are symbolic versions of powers of 10 Example: = m= milli
