  1. Unit 1: Basic Concepts of Chemistry Moles Chemical Reactions

  2. Unit 1: Basic Concepts of Chemistry The Mole Concept Molar Mass and Mole Calculations How many atoms of carbon are in 16.5 grams of oxalic acid, H2C2O4? % Composition, Empirical, Molecular Formulas

  3. Unit 1: Basic Concepts of Chemistry Balanced Chemical Equations P4 + O2 P4O10 C8H18 + O2 CO2 + H2O General Types of Reactions

  4. Unit 1: Basic Concepts of Chemistry Precipitation Reactions AgNO3 + KCl Net Ionic Equations

  5. Unit 1: Basic Concepts of Chemistry Acid and Base Neutralization Arrhenius Definition for now . . . Strong acid with strong base Weak acid with strong base

  6. Unit 1: Basic Concepts of Chemistry Oxidation – Reduction Reactions Chemical reactions that involve electron transfers! Ag+ (aq) + Cu(s)  Ag (s) + Cu2+ Recognizing oxidation reduction reactions: Fe2O3 + Al  Fe + Al2O3

  7. Unit 1: Basic Concepts of Chemistry Reaction Practice Predict the products and write balanced, net ionic equations for: 1. A solution of lead(II) nitrate is added to a solution of potassium bromide. 2. Liquid methane combusts completely with air. 3. Equamolar amounts of nitric acid and potassium hydroxide are mixed. 4. Aluminum powder is dropped into a 2.0 M iron(II) nitrate solution and allowed to sit over night. Further classify each reaction as a precipitation, acid-base or oxidation-reduction reaction.
