CHEM 455: Physical Chemistry 1

We categorize elements into representative, transition, inner-transition, and noble gases based on their positions in the periodic table and general characteristics, without revealing specific element classifications.

Discover how to determine the final temperature of a water sample after heat absorption. Utilizing the concept of specific heat capacity and the formula q = mc?T, we calculate the change in temperature and reveal its new state. Experience the transformation from an initial tepid state to a drastically altered thermal condition.

Learn the intricacies of Boyle's Law through an example involving isothermal compression of a perfect gas. Watch as we calculate the original pressure using the change in volume and final conditions. This tutorial simplifies complex gas laws for easy comprehension.

Explore the fascinating discovery of a glucose polymer with alternating glycosidic linkages. We'll visualize its Haworth projection and investigate its potential role in organisms, pondering whether it primarily serves a structural or energy storage function. Additionally, we'll discuss which types of organisms might utilize this unique polysaccharide as a potential food source.

Learn about mass changes in an iron bar when exposed to moist air, including the formation of rust (Fe?O?) and how to calculate the final mass.

Uncover the distinct behaviors of hydrochloric acid and acetic acid in water. Learn about the complete ionization of strong acids and the partial ionization of weak ones, emphasizing the differentiation in proton donation.
