Offering Note: No additional information available.

Description
An investigation of the fundamental structure of matter and chemical terminology. Introduces topics such as solution chemistry, thermochemistry and gas laws. Designed for science and pre-professional majors. Students enrolled in CHEM 121 should have taken or have concurrent enrollment in MATH 127 or MATH 128 .

Student Learning Outcomes

Identify salts, acids, and bases from their molecular formulas, to include the relationship between the structure of a molecule and its chemical and physical properties.
Identify the subatomic particles of an atom, their charges and relative masses.
Balance chemical equations and compute stoichiometric relationships including limiting reagents, molarity, titrations, dilutions and thermochemical equations.
Predict periodic trends in atomic and ionic size, ionization potential and electronegativity.
Draw Lewis structures for p-block molecules and their three-dimensional representation.
Use the ideal gas law to calculate pressure, volume, and temperature relationships.
Explain various intermolecular forces within a chemical system.
Demonstrate laboratory techniques, including the proper and safe use and handling of glassware, the techniques and processes common to many scientific labs, standard methods for recording observations and data, performing accurate quantitative measurements.
Analyze and interpret experimental results and develop appropriate and accurate conclusions.
