CHM 121: Chemistry for the Biosciences I

In this chemistry tutorial learn how to calculate the molar mass of various compounds using atomic masses from the periodic table. Discover the molar mass for compounds such as Strontium Hydroxide Dinitrogen Trioxide Sodium Chlorate and Chromium(III) Oxide. A concise guide to understanding molar masses and their real-world applications.

This explanation delves into the phenomenon where the reaction rate decreases over time due to the decrease in reactant concentration, resulting in fewer successful collisions and reactions, without revealing specific examples or findings.

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.

Explore the chemical combination of nitrogen and fluorine to produce nitrogen trifluoride. Learn how to determine the limiting reactant and calculate the theoretical yield using stoichiometry principles.

Unravel the electron configurations of diverse ions and discern their noble gas resemblances. Understand how atoms and ions strive for full outer electron shells for ultimate stability.

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.
