http://catalog.sierracollege.edu/course-outlines/chem-0002x/

Catalog Description Prerequisite: Completion of MATH A with grade of "C" or better, or placement by matriculation assessment process, or equivalent Corequisite: Concurrent enrollment in CHEM 2A Advisory: Eligibility for ENGL 1A; completion of CHEM A with grade of "C" or better or equivalent; completion of MATH G with grade of "C" or better or equivalent Hours: 18 lecture Description: Optional problem solving course to accompany CHEM 2A. Students use critical thinking and problem solving strategies to solve chemistry problems in topics that include atomic structure, the mole concept, gas laws, stoichiometry, redox, acid-base theory, equilibrium, nuclear chemistry, and chemical bonding. (CSU) Course Student Learning Outcomes CSLO #1: Solve problems related to structure and properties of matter, atomic and molecular structure, chemical formulas and stoichiometry, and chemical and physical equilibrium. CSLO #2: Apply mathematical problem solving techniques to solve problems in chemistry. CSLO #3: Develop rules and strategies for problem solving that are effective in solving new sets of problems. Effective Term Fall 2022 Course Type Credit - Degree-applicable Contact Hours 18 Outside of Class Hours 36 Total Student Learning Hours 54 Course Objectives Students will: 1. Apply mathematical problem solving techniques (algebraic equations, unit factor method, etc.) to solve problems in chemistry; and 2. Identify by using a diagram, a list, an equation, and/or words, the basic chemical concepts and principles affecting a given chemical system; 3. Solve problems related to unit conversions, atomic structure, the mole concept, gas laws, stoichiometry, solutions, oxidation/reduction, acid-base theory, equilibrium, and nuclear chemistry; 4. Build a conceptual model of the given chemical formula and determine the shape, polarity and predict the physical properties; 5. Develop strategies for problem solving that can be applied to solving new sets of problems. General Education Information Approved College Associate Degree GE Applicability CSU GE Applicability (Recommended-requires CSU approval) Cal-GETC Applicability (Recommended - Requires External Approval) IGETC Applicability (Recommended-requires CSU/UC approval) Articulation Information CSU Transferable Methods of Evaluation Classroom Discussions Example: If 95.5g of zinc reacts with excess HCl and 2.5g of hydrogen gas is collected, what is the percent yield? After students work out the problem on their own, the instructor will guide a class discussion of how to solve the problem. Instructor will ask for feedback from students regarding what strategies were used. Both the problem solving and the discussion will be graded solely on participation. Problem Solving Examinations Example: Problem Solving and Classroom Discussion: To a beaker containing 25g of zinc, 25mL of 0.100M HCl is added. Decide which reactant is the limiting reactant and justify your answer with the appropriate calculations. After students work out the problem on their own, the instructor will guide a class discussion of how to solve the problem. Instructor will ask for feedback from students regarding what strategies were used. Both the problem solving and the discussion will be graded solely on participation. Repeatable No Methods of Instruction Lecture/Discussion Distance Learning Lecture: Instructor demonstrates problem solving skills/techniques for working on limiting reactant stoichiometry problems. Instructor presents problems regarding limiting reactant stoichiometry. Students are expected to use techniques demonstrated to work out problems related to limiting reactant stoichiometry. In the distance learned modality a video and/or worked out examples will be provided and the student will work on problems using the LMS quiz feature or will upload their hand written work for grading. Distance Learning Instructor demonstrates problem solving skills/techniques for working on gas law problems. Instructor presents problems regarding gas laws. Students are expected to use techniques demonstrated to work out problems related to gas laws. In the distance learned modality a video and/or worked out examples will be provided and the student will work on problems using the LMS quiz feature or will upload their hand written work for grading. Typical Out of Class Assignments Reading Assignments 1. Read a section from the textbook or other printed material on gases. Be prepared to participate in class discussion and complete assigned problems. 2. Read the sample problems from the handout and be prepared for discussion. Writing, Problem Solving or Performance 1. Write a strategy for solving stoichiometry problems. 2. Solve problems provided on a problem-solving worksheet. For example, calculate the amount of energy required to raise the temperature of 50 grams of water 50 K.
