Acids and Bases Outline
-def - when dissolved in water, solution will conduct an electric
-due to presence of ions (charged atoms) in soln.
-all ionic cmpds (Na+ Cl-)
-some polar covalent cmpds, such as acids, which dissolve
MATH UNIT NOTES
I. Formula Types
- shows total # of each atom in a molecule
- simplest proportion of atoms in a compound
Ex. C6H12O6 would be CH2O
H2O would be H2O
- all ionic cmpds show this
KINETICS AND EQUILIBRIUM UNIT
I. A. Law of Conservation of Energy
-energy (heat) is neither created nor destroyed in a rxn.
-it can be accounted for in equation.
All compounds have potential energy-STORED energy (heat).
B. Activation Ene
Unit 4 Outline
-occurs when 2 nuclei both want the same electron(s).
-electronegativity difference between the 2 nuclei tells us what
type of bond it is.
Smaller difference e- SHARING COVALENT
Bigger difference e- TRANSFER IONIC
Say it ag
Unit 2 Atomic Structure
I. History of Atom Big Picture
A. 450 BC - Democritus (Greek)
-matter composed of tiny, indivisible particles atomos
4 Elements in constant motion:
-earth, air, water, fire
B. Late 1600s:
-properties of air due to particles
Chemistry Notes Packet #1
I. Problem Solving
A. Dimensional Analysis (also called Factor-Label Method)
-the technique of converting between units
Ex: English to metric (gallons to liters)
Metric to English (kg to lbs.)
Metric to metric (m to cm)
Topic 12 Outline Nuclear Chemistry
I. Nuclear Reactions
-chemical rxn: outer e-s interact, nucleus unchanged
-nuclear rxn: nucleus s to nucleus of different element
-called a transmutation
A. Stability of Nuclei
-depends on # of neutrons (protons (+) repe
Solutions and Solubility Packet
A. Properties of Solutions
def- homogeneous mixture of two or more substances
1. Dissolved particles not visible
2. Particles evenly distributed
3. Wont separate out under constant conditions
Solids, Liquids, Gases Outline
A. Kinetic Molecular Theory of Gases (KMT)
-theoretical model of ideal gas*
1) Gases -individual particles in continuous, random motion
-move in straight lines until deflected
2) -collisions btwn particles transfer
I. Redox Reactions
Oxidation process by which a substance loses e-.
Reduction process by which a substance gains e-.
One cannot occur without the other.
LEO the lion says GER.
Ex: Mg + Cl2
Mg loses 2 eCl2 gains 2 e-
-def: the study of carbon and carbon cmpds
-organic cmpd - cmpd with C atom at center; or with C atoms as
-find many in nature
-# organic > # inorganic cmpds
-Raw materials from which org
Unit 3 - Periodic Table
A. Valence e-s - e-s in outermost principal energy level.
1) Draw e- configuration
2) Identify outermost principal energy level
-e-s occupying this level are valence e-s
3) Simplified: # of e- in each level (no sublevel)
