BIOL CH 20: BIOL CH CHEM 20A

Discover the incredible speed of light as it zips 7.5 times around Earth in just a second! Marvel at its daily and yearly travels, equating to billions and trillions of kilometers. Dive deeper into the concept of a 'light year' and its significance in astronomical measurements.

Discover the process of determining the final temperature of an iron nail after heat absorption. Using the specific heat capacity of iron and the heat transfer formula, we calculate the temperature increase and reveal the nail's new thermal state. This tutorial offers a clear understanding of how materials respond to heat.

This video delves into the fundamental concept of conjugate bases in the context of the Brønsted-Lowry theory of acids and bases, explaining how when acids donate protons, they transform into their respective conjugate bases. This understanding is exemplified through the specific reactions of various compounds, illustrating how each Brønsted acid, upon proton donation, gives rise to its corresponding conjugate base.

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.

Unraveling HNO? Titration: Calculating [H?] Halfway with KOH. Harness the Henderson-Hasselbalch equation for pH determination. Discover the pH at midpoint between weak acid and strong base titration.
