CHEM 137: Adv Gen CHEM I and II Lecture

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.

Unraveling Molecular Structures: Explore the composition of compounds with molecular formulas CH4O, CH3Cl, C2H6, CH5N, C2F6, C2H5Br, and C3H8. Learn about their unique structures and properties.

Explore how to calculate the mass and volume of ethylene glycol, a common antifreeze, using its density. Understand the essentials of density-related calculations.

Join us in this video as we debunk common misconceptions about the periodic table. We explore and clarify statements regarding atomic size, electron configurations, reactivity, and electron removal. Dive into the world of chemistry and gain a deeper understanding of the periodic table's fascinating principles.

In this video, the presenter demonstrates the process of calculating the volume of 125g for three different liquids—Acetone, Olive oil, and Chloroform—using the formula "Volume = Mass / Density," providing step-by-step solutions for each liquid, ultimately revealing their respective volumes. This instructional video guides viewers through the calculations and showcases the outcome for each liquid's volume.

This video breaks down the process of calculating the time and number of photons required to boil water in a microwave. Using given power, wavelength, and water specifics, we determine both energy needs and photon count.
