Chemistry A

This comprehensive course gives students a solid basis to move on to future studies. The course provides an in-depth survey of all key areas, including atomic structure, chemical bonding and reactions, solutions, stoichiometry, thermochemistry, organic chemistry, and nuclear chemistry. The course includes direct online instruction, virtual laboratories, and related assessments, used with a problem-solving book.Materials: Chemistry Problems and SolutionsPrerequisites: Satisfactory completion of either Middle School Physical Science or High School Physical Science and solid grasp of algebra basics, 1.0 credit in Algebra I

CourseLabDescription (unit, content, & brief description of the lab)Chemistry AUnit 1 Lab: Paper ChromatographyIn this lab you will experiment with the principles of paper chromatography and how this method can be used to separate the component chemicals that make up an ink mixture . You will compare the size of the pigments based on the distance traveled along the stationary phase and the solubility of the mixture in the solvent. Unit 2 Lab Simulation: Average Atomic MassIn this laboratory exercise, you will use a simulation to practice calculating the average atomic mass of several elements. You will also create your own mixtures to see how changing the relative abundance changes the average atomic mass. Unit 3 Modeling Periodic TrendsIn this laboratory exercise, you will create a three-dimensional model of part of the periodic table using ionization energy. You will use your model to explain reactivity of metals and nonmetals. Unit 4 Lab Simulation: Melting Points of Ionic compoundsThe simulation is used to determine the melting points of several ionic compounds. Look for a trend in melting point as the cationic radius changes between sodium fluoride, potassium fluoride, and rubidium fluoride and as the anionic radius changes between sodium fluoride, sodium chloride, and sodium bromide. Unit 5 Lab Virtual: Types of Chemical ReactionsPerform and observe different types of chemical reactions by working in a virtual lab environment. Predict products, write reactants and products, determine aqueous and solid using the solubility chart and balance. In this lab you will perform synthesis, single-displacement, and double-displacement reactions. Unit 6 Lab Virtual: Stoichiometry of Chemical Reactions You will combine reactants in a quantitative manner and estimate the amounts of products. Unit 6 Lab Stoichiometry Simulation: In this modeling activity, you are provided with nitrogen and hydrogen atoms. Use the models to explore the concept of limiting and excess reactants. Calculate moles produced and determine the limiting and excess reagent.
