Comprehensive Final Exam Study Guide
Logistics: The final exam is scheduled for Thursday, July 21st from 10:20 am to 12:30 pm in our typical lecture room (609). PLEASE BRING AN ORANGE PARSCORE FORM.
Roughly half of the exam will cover the most recent material; included below is a list of topics to focus on for this last unit of the class. The other half of the exam will cover material from the last three midterms (Exam 1, Exam 2, Exam 3). Anything included on these previous study guides is fair game for the final. To help direct your studying, I've also roughly prioritized topics that I believe are central to your success in this course and future work in chemistry. Reviewing old exams, suggested homework and practice problems on the Review Materials page are all good ways of studying.
Disclaimer: Practice Exams from previous semesters may cover more or less material than the current semester. No two problems will likely ever be the same. Avoid memorizing how to solve a specific problem, and instead focus on the concepts and logic necessary to problem solve.

TOPICS FOR PRIORITY REVIEW:
- The concept of the MOLE and unit conversions Download The concept of the MOLE and unit conversions involving: molar mass, density, concentration, and gas laws. Understanding these relationships will take you a long way in this course and chemistry in general. Until you can work through problems involving these concepts, I wouldn't focus on anything else.
- Writing, categorizing, and balancing chemical reactions, including phase symbols (using the solubility chart Download using the solubility chart).
- This includes being able to write the correct and proper formulas for substances. To do this, you should be familiar with the rules for nomenclature, know the charges of ions based on their position in the periodic table, and memorize the polyatomic ion names Download memorize the polyatomic ion names.
- Stoichiometry Calculations using Mole-to-Mole Ratios Download Stoichiometry Calculations using Mole-to-Mole Ratios (from balanced chemical equations): including calculations to determine the theoretical yield, limiting reagent, reagent in excess, percent yield and actual yield.
- Drawing Lewis Dot Structures Download Drawing Lewis Dot Structures and using these to predict molecular shapes Download predict molecular shapes and polarities Download polarities
CHAPTER 13 & 14 REVIEW:
- Solutions:
- Understand the difference between the solute, solvent, and solution
- Understand how different solutes affect the electrical conductivity of the solution
- Most ionic compounds are strong electrolytes which conduct electricity in solution
- Most covalent compounds are NON-electrolytes which do not significantly conduct electricity in solution
- Concentrations:
- Be able to calculate the concentration of a solute in units of:
- Molarity (moles/L)
- Mass Percent
- Parts per million (ppm)
- The equations for these calculations will be provided but you must know how to use them
- Be able to solve for the total quantity of the solute based on the concentration and volume of solution provided
- Be able to use the dilution equation (M1V1=M2V2) to understand how concentration changes and volume changes during dilutions
- Solution Stoichiometry & TITRATIONS:
- Provided the concentration in molarity and volume in liters, find the moles of a reactant or product and use this as in an other stoichometry problem
- Based on the moles of one reactant, solve for the moles of another reactant, then use this quantity in combination with volume to find concentration
