TC3 CHEM 1XX Syllabus; Dr. Zisk
1st Semester
1. Unit 1: Matter and Energy...
A. Matter
i. Definitions
Start with atoms, smallest matter, then build...
Seven major concepts:
1)Elements, 2)compounds, 3)mixtures
Don't forget looser term "substances"
Use of 4)physical, 5)chemical properties/separations
Distinguish 6)homogeneous and 7)heterogeneous mixtures
ii. Density and constant composition of compound introduces math
d=m/v but solve for m or v...show them
Water 11% hydrogen, 3g hydrogen means how much oxygen?
iii. Mention phases, but note unit #2
B. Energy
i. Four Questions:
What is it? Can do work...don't forget KE vs PE, and subtypes
What's "conservation"? Gets converted, but never destroyed
In chem, where's it come from? bonds formed ...Endo/Exo
What's temperature? Is it heat?
ii. Segue into heat capacity; the hot(water vs. Pb) in the hand demo
iii MC∆T=∆H
Explain delta
Relates heat and temperature
Mass of given C will change T in relation to H in or out
iv. Celsius-Kelvin (abs. zero)
2. Unit 2 Phases...

iv. KE and PE changes as we go?
B. Heats of fusion and vaporization (see the plateaus on temp:time)
i. Calculations

3. Unit 3: Gas laws...
A. Start with a balloon for all of these

ii. What's ion?! We haven't defined electron movement!!... Shortly, not now...
iii. Isotopes
D. Most important: Electrons around a nucleus
i. Shells, or "levels"
ii. Movement between levels
Students graph me climbing on chairs, desks, cabinets etc.
No in-between places; energy release upon falling, absorb to climb
Hence the image of quantized transitions, the Bohr Model
iii. E=hƒ; ƒ=c/w; are they comfortable yet with powers of ten?
iv. Radiation; spectra; fingerprints
continuous vs. discrete
bright-line vs absorption
again, E=hƒ

∆H vs Rxn Coordinate-- what's happening here??
Bonding or any chemical∆ is always accompanied by energy∆
Cf units on Kinetics/Equilib and on ElectroChem: Chem doesWork
Foreshadow the Reverse/Forward DG-driven equilib we'll see later
iii. And we need a formalism: Using Lewis dot diagrams
iv. These are, broadly put, valence electrons-- but we'd better definehybridization

D. Using an activity series
All are given in the series as reductions, as the cathode reaction
Defining stronger/weaker reduction potentials as voltages; ∆G=-nFE
The weaker half reaction, lower on the series, must proceed as ox
