CHEM 127: ST:General Chemistry I-A

Explore the protonation of amino acids, specifically valine and threonine, when subjected to a pH lower than their isoelectric points, highlighting the structural changes in their carboxyl and amino groups.

Discover the step-by-step process of Barium Sulfate formation from the reaction of Barium Chloride with Sodium Sulfate. Learn about molar mass calculations stoichiometry and yield predictions.

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.

When an ionic compound dissolves in water, it undergoes dissociation into its constituent ions. The total moles of ions released is determined by adding up the moles of each ion generated during this dissociation process. In the case of (a) disodium hydrogen phosphate (Na?HPO?), it dissociates into two sodium ions and one hydrogen phosphate ion. For (b) copper(II) sulfate pentahydrate (CuSO? · 5H?O), it dissociates into one copper ion and one sulfate ion. In (c), nickel(II) chloride (NiCl?) diss

Explore the intriguing reaction of gaseous Nitrogen Dioxide and Hydrogen, resulting in the formation of Ammonia and Water. Grasp the significance of balanced chemical equations in respecting the law of conservation of mass. Dive into the properties and characteristics of each involved compound.

The kinetic molecular theory of gases describes the random motion and speed distribution of gas molecules in a container, and when considering various statements about the average speeds of these molecules, it's important to understand how they behave under different conditions.
