More lessons on Chemistry.
This is a series of lectures in videos covering topics in General Chemistry. They are conducted by Dr. Chuck Wight who teaches chemistry at the University of Utah.
Matter and Measurement
This is the first in a series of lectures covering topics in General Chemistry. We discuss the scientific method of research and the classification of different kinds of matter as elements, compounds and mixtures. The lecture ends with a review of some important chemical and physical properties of matter.
Units and Uncertainty
This General Chemistry lecture covers the SI system of units and scientific laws covering conservation of mass and energy. We discuss the distinction between accuracy and precision, and explain how to determine and report the number of significant figures in an observation or result of a calculation.
Solving Problems in Chemistry
In this General Chemistry lecture, we introduce a 7-step general method for solving problems in chemistry. Two examples are shown, one non-chemistry problem involving the calculation of the shared cost of a meal. The second problem is to compute the mole fraction of tin in bronze.
Atoms and Elements
In this General Chemistry lecture we discuss the nature and structure of atoms, the Law of Definite Proportions, and the Law of Multiple Proportions.
