3 Credit(s)

Designed to prepare students with minimal chemistry experience to take CH221. Topics include measurement, significant figures, dimensional analysis, density, nomenclature, atoms, stoichiometry, gases, solutions and heat; includes problem solving methods and calculations. Lecture/Recitation.

Prerequisite: MTH 065  or above with grade of C- or better or pass placement test.
Learning Outcomes
Upon successful completion of this course, the student should be able to:

1. Use measurements written in scientific notation.

2. Analyze uncertainty in measurements, apply rules of significant figures.

3. Solve dimensional analysis (unit conversion) questions, apply problem solving techniques to a variety of real life questions.

4. Calculate density or use density as a conversion factor.

5. Distinguish between different types of compounds.

6. Name chemicals given a formula or write a formula given a name.

7. Identify the components of an atom, identify isotopes.

8. Identify when the concept of a mole is used correctly or incorrectly and use a mole to solve a variety of chemistry questions.

9. Calculate molar mass, % composition, empirical and molecular formulas.

10. Write and balance chemical equations, distinguish between different types of reactions.

11. Use and apply previous concepts to solve stoichiometry problems.

12. Observe the properties of gases, solve gas law questions.

13. Determine the concentration of a solution, apply stoichiometry concepts to solutions. 

14. Be prepared to take and succeed in CH 222.
