CHEM 130: Survey of Organic and Biochemistry

In this video, we classify substances as elements, compounds, or mixtures, with air and soy sauce as mixtures, iron as an element, and table salt as a compound.

We explore synthesis and decomposition reactions, showcasing examples like the formation of water and its breakdown into simpler substances. We also clarify that while many of these reactions are redox reactions involving electron transfer, some synthesis and decomposition reactions may not necessarily be redox reactions, as seen in specific examples.

In this tutorial, we break down the principle of density, illustrating it as a measure of mass per unit volume. Using an osmium cube as a practical example, we walk viewers through the steps of computing its density, demonstrating the interplay between mass, volume, and particle arrangement.

In this video, we delve into the fascinating world of evolutionary adaptations in heme-containing proteins.

Master metric unit conversions with step-by-step examples, including cm to meters, g to kilograms, cm to millimeters, and mL to liters.

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.
