CHEM 105: Elements of Chemistry

Discover the process of naming acids based on their anions and oxidation states. This video breaks down the correct naming of HNO2(aq) by distinguishing its anion and determining its place in the world of mineral acids.

Explore the polar nature of Chloromethane and the nonpolar characteristics of Methane. Understand the impact of electronegativity differences and bond types. Deciphering molecular polarity through the lens of tetrahedral structures.

Unpack the difference between quantitative and non-quantitative observations. Examples include a person's weight on the Moon and the depth a hand pump can reach. Learn why precise measurements are crucial in scientific studies.

Discover the art of writing balanced, complete ionic, and net ionic equations for various chemical reactions. Learn the nuances that differentiate between these equations and watch them applied to diverse chemical reactants.

Discover how to calculate the number of moles of hydrogen in different chemical samples, including H?O, NH?, N?H?, and C??H??.

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.
