Inorganic chemistry
Lesson Explainer: Dynamic Equilibrium
Lesson Explainer: Dynamic Equilibrium In this explainer, we will learn how to define a dynamic equilibrium and examine how one can be established. Let us consider the following reversible chemical reaction: At the very start of the reaction, the concentration of nitrogen and hydrogen gas is high, while the concentration of ammonia is zero as it has not yet been … [Read more...] about Lesson Explainer: Dynamic Equilibrium
The Chemical Sciences Inorganic Chemistry
The Chemical Sciences Inorganic Chemistry What is inorganic chemistry? Inorganic chemistry is concerned with the properties and behavior of inorganic compounds, which include metals, minerals, and organometallic compounds. While organic chemistry is defined as the study of carbon-containing compounds, inorganic chemistry is the study of the remaining (i.e., not … [Read more...] about The Chemical Sciences Inorganic Chemistry
The Shapes of Molecules (VSEPR Theory) and Orbital Hybridization
The Shapes of Molecules (VSEPR Theory) and Orbital Hybridization The Valence Shell Electron Pair Repulsion (VSEPR) theory is a simple and useful way to predict and rationalize the shapes of molecules. The theory is based on the idea of minimizing the electrostatic repulsion between electron pairs, as first proposed by Sidgwick and Powell in 1940, then generalized by Gillespie … [Read more...] about The Shapes of Molecules (VSEPR Theory) and Orbital Hybridization
Prelude to Chemical Bonding
Prelude to Chemical Bonding Molecules (and extended solids) are built from atoms that form chemical bonds. Theories of bonding seek to explain why molecules and solids form, what their structures are, why some are more stable than others, and how they react. As we will learn in Chapter 2, quantum mechanics gives us the most realistic picture of chemical bonding via molecular … [Read more...] about Prelude to Chemical Bonding
