Chemical Kinetics

Chemical Kinetics Chemical Kinetics examines the rate of a chemical reaction by looking at how quickly reactants break down to form products. The examination of a reaction’s rate includes topics such as General or Average Rate, Rate Law, the Integrated Rate Laws, the Arrhenius Equations, reaction mechanisms and energy diagrams. Read more…

Atoms & Elements

Atoms & Elements The Periodic Table is a representation of the different elements that exist in order of increasing atomic mass. Within a given atom or ion we have a set number of protons, neutrons and electrons and the Periodic Table gives the average mass of the elements’ isotopes. Below Read more…

Introduction to General Chemistry

Intro to General Chemistry Chemistry examines the different forms of matter and the changes that it can undergo. From the beginning we will examine the various properties of matter, the theories involved in examining matter and the calculation setups that will form the foundation of much of your chemistry exploration.

Percent Error

Precision and Accuracy When we investigate the quality of an experimental decision or calculation we take into account two major principles: The first principle, which deals with the reproducibility of our calculations, is called precision. The second principle called accuracy deals with how close our measured calculation is to the Read more…

Molecular vs Electron Geometry

Molecular and Electron Geometry The shape of a chemical compound is essential in understanding its polarity and by extension its intermolecular forces. For now let’s review the key differences and similarities that exist with the molecular geometry and electron geometry of Lewis Dot Structures. Molecular & Electron Geometry

Periodic Properties

Periodic Properties of the Elements The atom represents the smallest indivisible part of matter, but its scientific foundations and theories are as expansive as a galaxy. Within a given atom we have our subatomic particles and the smallest ones called the electrons have a big impact on  physical and chemical Read more…

Condensation Reactions

Condensation reactions are reactions in which two molecules combine to form a larger molecule, producing a small molecule such as H2O as a byproduct. They typically form a new carbon-carbon bond and result from a nucleophilic enolate and an electrophilic carbonyl.  P.S. Here is the 2-hour super-comprehensive version if you are not Read more…

pKa Values

pKa and Acidity The acidity of a compound can be determined by examining its structure, the stability of its conjugate base or by simply looking at its pKa value. The stronger the acid then the lower its pKa value. Given below are the pKa values for the most commonly discussed Read more…
