Chemistry Final Study Guide s1

Chemistry Final Study Guide

Your final will cover the topics listed below:

Unit conversions

Scientific Notation

Significant figures

Periodic table elements metals non-metals transitional metals atomic wright atomic number #'s of protons, electrons, neutrons periodicity electronegativity atomic radii electron configurations and how they reflect how electrons fill the subshells

Vocabulary ion isotope valence electron and any other terms you come across with which you are unfamiliar

Bonding Covalent, Polar Covalent, Ionic -- differences between and how to tell which is which Which form molecules, which form crystal lattices? Which do the terms "molecule" and "compound" refer to? Bond shapes Lewis Dot Structures Nomenclature - how to name compounds

Chemical Formulas Empirical vs. Molecular How to calculate the atomic mass of a compound How to calculate % composition

The Mole!

Balance chemical equations

Chemical Reactions Types -- synthesis/combination, decomposition, single displacement, doulble displacement (including predicting products and solubility), and combustion

Redox reactions - be able to identify them and determine what was reduced and what was oxidized (LEO the lion says GER)

Stoichiometry -- which is really just kitchen chemistry with the reactions being the recipes.... Remember the grams to moles to moles to grams graphic(s) You can NOT compare grams to grams .... always go through moles!

Gas Laws - be able to identify which formula to use -- you will be able to use your gas laws cheat sheet. Know how to convert units to the ones we use -- L, atm and K

Phase changes - Know how to use George and heat of vaporization and heat of fusion. Know what the specific heat is. Know how to interpret a phase change diagram.

Colligative Properties - know what they are and what their trends are

Acids/Bases - know that acid + base ---> salt plus water; recognize that H+ ions determine pH.
