The laboratory course provides hands-on experience in chemical measurement, data analysis, and the application of scientific methods. Students will learn to obtain and analyze experimental observations using diverse laboratory techniques.

Course Objectives

• Demonstrate the use of significant figures and perform calculations with measured values.

• Apply measurement instrumentation (both analog and digital) for chemical analysis.

• Record and analyze laboratory data, including the use of graphs and tables.

• Master basic laboratory techniques such as weighing, measuring, and sample preparation.

• Draw experimental results and relate them to chemical concepts.

• Present experimental results in laboratory reports with appropriate format and depth.

• Observe chemical reactions and classify different types of reactions.

• Relate laboratory experimental observations, operations, calculations, and findings to theoretical concepts.

Required Materials

• Textbook: Exploring Chemistry: Chemistry 1120L Lab Manual

• Safety Equipment: Splash goggles (purchased from the CNM Bookstore or other supplier)

• Scientific Calculator: Required for calculations and data analysis

Course Requirements & Policies

Safety
