The Stoichiometry of Product Formation and Percent Yield

Solution stoichiometry allows us to quantify the amount of a substance in a solution.

Light is composed of electric and magnetic fields and thus its alternate name "electromagnetic spectrum". Light can be absorbed and emitted by atoms and molecules. The precise details of which give us the world we see around us.

Photoelectric Effect

According to the physics of the time, Rutherford's planetary atom should have an extremely short lifetime. Bohr thought about the problem and knew of the emission spectrum of hydrogen. He quickly realized that the two problems were connected and after some thought came up with the Bohr model of the atom. Bohr's model of the atom revolutionized atomic physics.

The equations of modern atomic theory are difficult to solve. Fortunately, many of the results can be obatined by following some simple rules. These rules are known as the Aufbau principle.

Because of the nature of ionic and covalent bonds, the materials produced by those bonds tend to have quite different macroscopic properties.

We are now ready to pull everything we know about reaction stoichiometry together, and answer the question: Given some initial amount of reactants, what should be present after a chemical reaction goes to completion? The procedure for answering this question is often called the "limiting reagent problem." You'll see why this name is appropriate in the following video.

Reaction stoichiometry allows us to determine the amount of substance that is consumed or produced by a reaction. The following video considers the first part of this: how much of a reactant is consumed in a chemical reaction. Product formation is discussed elsewhere.
