Document Summary

Topics included: atoms, compounds, reactions, gases, the periodic table, bonding. Isotope = occurs when the number of neutrons vary for a particular element. the number of protons do not vary. Given any two of these variables, be able to solve for the third: weighted average atomic mass, isotopic mass, fractional abundance. Counting protons, neutrons, and electrons in elements and ions. Nomenclature: aqueous acids, molecular compounds, ionic compounds, straight- chained alkanes. Anytime we have an isotope, we look for a weighted average. Writing reactions (net ionic, double, single, combustion, combination, decomposition, neutralization, precipitation) Stoichiometry problems where information related to moles is given for 2 or more reactants. Combined gas laws (including charles, boyle, etc. ) Dalton"s law (mixture of 2 or more gases) Ideal gas law (& d = m/v & m = m/n) Two molecules at the same temperature will have the same average kinetic energy. If two molecules are under the same conditions, the heavier molecule will travel slower.
