Graham's Law, the Combined Gas Law, Boyle's Law, Charles' Law and Guy-Lussac's Law--we'll visit them all. Unit 12: Liquids and Solutions In this brief unit, we will revisit solutes, solvents, and concentration units.We will interpret solubility graphs to solve problems and relate this to our knowledge of intermolecular attractions.We will also investigate the effect of stresses on equilibrium systems. We will also apply our understanding of equilibrium to acids and bases.Unit 14: Acids, Bases, and Salts (Chapter 16) We eat oranges and cook with vinegar--everyday sources of acids. Unit 15: Redox and Electrochemistry Some chemical reactions convert chemical energy into electrical energy.Students learn how to use dimensional analysis (also known as factor-label) in problem solving.We then proceed to comparing different classifications of matter on both the macroscopic and microscopic (particle) levels.
(We will supplement the textbook, which doesn't go into enough detail regarding reaction kinetics.) We will then explore reversible reactions and develop the concept of equilibrium and the equilibrium constant.We clean the windows with ammonia solutions and use Drano to unclog the sink--everyday sources of bases. This occurs when atoms gain electrons ("reduction") or lose electrons ("oxidation"). Additionally, these reactions can be harnessed to create batteries!We will use our knowledge of oxidation-reduction processes (or "redox") to predict the voltage produced in electrochemical cells. We start by exploring appropriate use of data in science, using significant figures for both measurements and calculations, through a series of hands-on activities.A number of interactive and visual resources will be used to enrich the learning experience.This year, students will complete a detailed creative writing assignment as the summative assessment for the unit. Unit 9: Nuclear Chemistry In this brief unit, we will consider the factors that make for unstable nuclei--and what then happens to those radioisotopes.
