Online Class: Chemistry 101
At a minimum, a basic understanding of chemistry is needed for it offers a foundation for comprehending the inner workings of biology (how cells function and the behavior of organisms), as well as, the ecological relationships that exist between organisms and their environment.
In short, chemistry offers us a way of understanding the world in which we live.
Chemistry provides us with insights into how our bodies function; the ingredients that are contained within the foods we eat; the reason cars, planes and trains are able to run as efficiently as they do; the manner in which computers are built and operate; and the materials used to construct our homes and buildings within our communities.
Basically, chemistry is a part of almost everything we do for everything is comprised of chemical compounds. The claim that chemistry is everywhere is, thus, entirely accurate.
Chemistry encompasses a multitude of specialized sub-disciplines which have proven highly useful to chemistry as they have provided for the following: the production and testing of stronger materials, creation of pharmaceuticals to treat disease, and the study of life processes.
Lesson 1. Atoms, Molecules, and Ions
The ordination of who was the true “father” of modern chemistry is a disputed point.
Lesson 2. Chemical Foundations
In chemistry the accepted measurement system for mass (m) or volume (v) is the metric system, also known as the System International (SI) system.
Lesson 3. Stoichiometry
Stoichiometry is the field of chemistry used to determine the quantities both for the required reactants of a chemical reaction and the predicted product of said reactions.
Lesson 4. Types of Chemical Reactions and Solution Stoichiometry
Most chemical reactions require a catalyst, a certain condition external to the reactants themselves that facilitates or causes the molecules to react with one another.
Lesson 5. Gases
Matter in gaseous form does not have an absolute density. In order to determine the density of any volume of gas, we must first determine the pressure under which the gas is being held.
Lesson 6. Thermochemistry
There are two types of energy, potential (the amount of energy possible given a certain circumstance) and kinetic (the amount of energy being expended).
Lesson 7. Atomic Structure and Periodicity
Electromagnetic radiation refers to the wavelengths on which energy travels through the Universe.
Lesson 8. Bonding. General Concepts
Hydrogen bonds are the bonds established between hydrogen and elements with a high level of electronegativity.
Lesson 9. Valence Bond Theory
Atoms form a bond when both of these two conditions occur 1) There is an “orbital overlap” between two atoms and 2) only two electrons, both of opposite spin, are present in the overlap.
Lesson 10. Properties and Solutions
Solutions are a combination of solutes and solvents, which are not necessarily composed of the same forms of matter.
Lesson 11. Chemical Kinetics
Chemical kinetics is concerned with the rates of chemical reactions.
Lesson 12. Chemical Equilibrium
The first thing to understand about equilibrium in chemistry is that it is a dynamic state.
Lesson 13. Spontaneity, Entropy, and Free Energy
Spontaneous processes occur without outside intervention. Some of these occur very quickly, such as combustion, whereas others like the formation of diamonds occur very slowly over millions if not billions of years.
Lesson 14. The Nucleus, A Chemist’s View
The nucleus of an atom is not always stable.
Lesson 15. Transition Metals and Coordination Chemistry
Many transition metals commonly form more than one form of oxidized compound depending on the conditions of formation.
Lesson 16. Organic Chemistry
Organic chemistry is the study of carbon based chemistry in the realm of living things.
