Course description

The course includes the topics of the study of Chemistry, classifying matter, physical vs. chemical properties, elements and the periodic table, chemical compounds and bonding, chemical reactions, the conservation of mass, avogardro’s number and the mole, chemical proportions in compounds, and molecular formulas. In order to satisfy the University of California A-G requirements for a chemistry course, two components are required. The first is our online course and the second is a wet lab. Our online chemistry course provides the curriculum with videos, quizzes, assignments and final.In this module, students gain a comprehension of the following: Great discoveries in Chemistry. physical and chemical properties, what they are, and their classifications. Learn the elements, what they are made of, and their places on the Periodic Table. Learn about orbitals, trends in the periodic table, and the atomic model. Introduction to electrons, what they are, and their importance. Learn what chemical compounds are, how they are formed, and their makeup. Look at ionic and covalent compounds and various types of chemical bonds. Learn how to write chemical formulas and balance chemical equations. Learn about different types of chemical reactions, including synthesis, decomposition, combustion, oxidation-reduction, single and double-displacement reactions, and acid-base neutralization. Learn about isotopes, what they are, and their place in the study of chemistry. Learn about atomic mass and what atomic mass is, and practice calculating atomic mass. Introduction to Avogadro’s number and the mole, learn what it is and how it is used in chemical equations. Converting between mass, mole, and the number of particles. Learn about the chemical proportions in compounds. Learn about chemical composition and how to calculate the percentage of composition. Review the empirical formula and learn its importance in the study of chemistry. Review the molecular formula and how to determine and calculate empirical and molecular formulas from chemical equations. Learn to titrate unknown substances and continue to practice converting between units. The significance of coefficients in a balanced equation, molar ratios, mole-mole calculations, mass-mass calculations and other stoichiometric calculations. To solve Limiting Reactant stoichiometry problems as well as how to determine the excess reactant. The difference between actual, theoretical and percent yields with examples of how to calculate theoretical and percent yields. The concepts of solutions and solubility. The chemical structure of water, and why water is so important for life. How and why water acts as a wonderful solvent and provides a medium for metabolism. The various factors that affect how well a solid-liquid solute dissolves, including Particle Size, Temperature, Agitation and the Chemical Nature of the solute, particularly polarity (Like dissolves like.) To interpret solubility curves and read solubility curves. To identify and understand saturated, unsaturated and supersaturated solutions. Colligative properties, freezing point depression and boiling point elevation. The relationship between amount of solute and degree of freezing point depression-boiling point elevation. The general properties of acids and bases. Including the Arrhenius definitions for acids and bases. Bronsted and Lowry’s theory of acids and bases. To distinguish between strong and weak acids and bases in terms of the extent of dissociation, reaction with water and electrical conductivity. The pH scale and to consider the effects of acid deposition on limestone buildings and living things.To understand the nature of a strong acid and a strong base. To solve acid-base titration math problems. The nature of gases as related to the study of Chemistry. The assumptions behind the Kinetic Molecular Theory and some general properties of gases from a molecular perspective. Avogadro’s Law, Boyle’s Law, Lussac’s Law and Charles’ law. How the ideal gas equation allows one to find the pressure, volume, temperature and/or number of moles in a certain situation. To measure and consider the rate of a reaction. The connection between concentration and reaction rate in terms of the Law of Mass Action and Rate Laws. The equilibrium constant (K,) and how it can be calculated in various reversible reactions. Le Chatelier’s Principle and how it predicts changes in concentration when “stressing” reactions at equilibrium. Nuclear structure and stability, radioactive decay, and nuclear energy. As well as, the biological effects of radiation as well as technology related to energy, medicine, geology, and other areas. Organic chemistry – why the element carbon results in such a variety of compounds, how those compounds are classified, and the role of organic compounds in biology and industry. This course covers the following topics: Observing Matter Elements and the Periodic Table Chemical Compounds and Bonding Chemical Reactions Conservation of Matter Chemical Proportions in Compounds Quantities in Chemical Reactions Solutions and Solubility Acids and Bases Gases Chemical Equilibrium Nuclear Chemistry Organic Chemistry
