Chem 1000 Final Exam Study Guide
Chapter 1 -Chemistry
1. Science – testable, reproducible, predictable, tentative, explanatory
2. States of matter – Solid, Liquid, Gas
a. Pure Substances vs. Mixture – pure water vs. tap water
b. Element vs. Compound – Atoms vs. Molecules
3. Numerical prefixes, Unit Conversion, Scientific Notation
4. Density = mass/volume – calculations
a. Sink vs. float
5. Temperature Calculations K = C + 273, Absolute Zero
Chapter 2 – Atoms
1. Avogadro’s Number (6.022 x 1023) – Mole – Atomic mas unit vs. Molar Mass
2. Law of Conservation of Mass, Law of Definite Proportions, Law of Multiple
Proportions
Chapter 3 – Atomic Structure
1. Atomic Structure – Electron, proton, neutron
a. Nucleus, subshell, energy levels, s-orbitals vs. p-orbitals
b. Electron configuration, Valence Electrons
2. Isotope – elements exist as a mixture of isotopes
a. Different number of neutrons, same number of protons and electrons
Chapter 4 – Chemical Bonding
1. Ionic Bonds – Transfer of electrons, loss or gain of electrons
a. Cation, anion, molecular formula for ionic compounds
2. Covalent Bonds – Sharing of electrons, Lewis Dot Structures
3. Electronegativity – Electronegativity difference – polar = hydrophilic, nonpolar
= hydrophobic
4. Polyatomic ions
Chapter 5 – Chemical Accounting
1. Balancing Chemical Equations
2. Stoichiometry Calculations
3. Concentration – Molarity = moles/Liter – Percent concentration
4. Solubility – how ions dissolve in water
5. “Like dissolves like” – Polar compounds dissolve in polar solvents
Chapter 6 – Solids, Liquids, Gases … and Intermolecular Forces
1. States of matter – Solid, Liquid, Gas
2. Phase Changes melting point, boiling point, condensation, freezing,
vaporization, etc.
