CHEM 111: General Chemistry I

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.

This discussion delves into the use of acetone as a solvent for removing water from laboratory glassware, exploring the science behind its effectiveness and the role of hydrogen bonding in facilitating rapid evaporation.

Explore the art of constructing Lewis dot structures for ionic compounds such as SrO Li2S CaI2 and RbF. Understand the electron transfer process by diving into each atom's valency and its role in compound formation. Unpack the intricacies of ionic interactions for a deeper chemistry insight.

Discover Lewis structures for various molecular formulas, including N2, HCN, CO2, C3H6, and more. Explore their chemical bonding and structural arrangements.

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, we explore the information that knowledge of the number of protons in a neutral element's atom can provide. Options for determining neutron count, electron count, and identifying the element's name are examined, with a conclusion that it allows us to know both the number of electrons and the element's name.
