CHM 1010: Introduction to Chemistry

Discover the differences between physical and chemical changes using common examples. Understand how sugar reacts in various scenarios, and how metals undergo changes, either maintaining their substance or forming new compounds.

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.

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.

The scenario involves an archaeologist analyzing iron in an old building containing nickel-63, which has a known half-life of 92 years. With only 0.78% of the original nickel-63 remaining, the goal is to estimate the year when this discovery was made. We delve into the calculations and principles of first-order decay reactions.

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

Explore the complex challenges scientists face when attempting to extract respiratory complexes from the inner mitochondrial membrane for an in-depth study of their properties and functions."
