CHEM 135: Chemistry for Engineers

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.

Explore the conductivity of aqueous solutions: Cesium bromide and hydrogen iodide. Understand their ionic nature and how it leads to the presence of charged ions enabling electricity conduction

This video explains the importance of the number of valence electrons in an element's chemical behavior and demonstrates how to determine the valence electrons for potassium, calcium, and aluminum based on their positions in the periodic table. Valence electrons dictate an element's reactivity with other elements, making this knowledge essential for understanding chemical reactions.

Dive into the accuracy of four chemical reactions involving compounds like Barium Nitrate and Lithium Chloride. Discover which reactions yield precipitates which are correct and which need correction. A comprehensive review from Barium Sulfate formation to Lead Chloride precipitation

Unravel the Lewis structures of BrF?, ClF?, and IF? and their relationship with the octet rule. Examine how fluorine bonds with bromine, chlorine, and iodine. Identify molecules that deviate from the standard octet distribution.
