AP Chemistry Final Review Trimester 1 This is a cumulative test for Trimester 1 for: Chapter 1 Foundations Chapter 2 Atomic Theory and Nomenclature Chapter ¾ Balancing and Reaction Types Chapter 3 The Mole and Stoichiometry Since we just tested Chapter 6 Thermo, it will NOT be included on the final. I have chosen 40 multiple choice questions for the final. You can use a yellow periodic table. You can look back over the study guides for these chapters to find practice problems. Otherwise, here is a rough sketch to help you focus: Understand the basic steps of the Scientific Method Understand the terms hypothesis, theory, and law and how they relate (or don’t) to each other Be familiar with the SI system (metric system) Distinguish between chemical and physical changes Know what the differences are between mixtures and pure substances Understand the organization of the atom and the characteristics of the 3 sub-atomic particles Be familiar with the development of the atomic theory in terms of Dalton, Thomson, and Rutherford Define, describe, and understand isotopes, atoms, and ions Be able to name and write formulas for binary and ionic compounds Be able to predict charges of ions and polyatomic ions Be able to balance chemical equations Be able to identify the different types of chemical reactions as discussed in class Predict the products and solubility of double displacement reactions (use the yellow) Convert from g—mol--# of atoms or molecules Use quantities and the unit analysis method Calculate % composition by mass Calculate empirical and molecular formula Have a heart for the mole ratio and stoichiometry
