Online Class: Chemistry 101

Course Description

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.

    Closed System in Chemistry: Definition & Example

    This lesson provides a basic definition of a closed system from thermodynamics. Examples are included to provide students with illustrations of closed systems that are encountered within chemistry.

    Definition of a Closed System

    You have probably put soft drinks in a cooler under ice to keep them cold. When the lid of the cooler is closed, nothing can get in or out, and the insulated walls appear to keep all of the contents nice and frosty. However, if enough time passes, the ice does eventually melt into water. This is an excellent example of a closed system. What is a system, and, more to the point, what is a closed system? How are closed systems used in chemistry?

    Cooler with iced soft drinks

    The concept of a system comes from thermodynamics. a branch of physics that studies the transfer of energy between objects and their surroundings. A system within thermodynamics is defined as part of the physical universe. The system could be a car engine, a mass of air in the atmosphere, or even a soft drink can. Systems are separated from the rest of the physical universe (or the surroundings) by a boundary that can real (such as the walls of a cooler) or imaginary, used to focus on a specific part of a complicated situation, such as the combustion cylinder within an engine.

    An engine with cylinders shown

    Systems are classified in three basic ways: open, closed, or isolated. These describe how energy and matter are allowed to enter or leave the system. Within an open system. matter and energy freely cross the boundary of the system. For example, the Earth can be considered an open system because sunlight reaches the surface of our planet, meteorites can enter our atmosphere, and we can send objects out into space. Closed systems. like the closed cooler described previously, allow energy to cross the boundary of the system, but matter is prevented from being added to or removed from the system. Isolated systems allow neither matter nor energy to cross the boundary of the system.

    The Earth, an open system

    Examples of Closed Systems in Chemistry

    Closed systems in chemistry are extremely useful for conducting chemical reactions, and rearranging atoms within matter to give new combinations of atoms. They are used in the laboratory as well as chemical industries such as the manufacture of medicines. The reactions occur in a special vessel known as a chemical reactor that has been sealed to prevent any matter from entering. The sealed reactor is now a closed system allowing for the careful control of the flow of energy across the walls of the reactor through heating or cooling.

    Online Chemistry Bachelor s Degree Program Information

    Research online chemistry bachelor degree programs. Find out what you can learn in these programs and what you’ll need in order to participate in online learning to determine if it’s right for you.

    Essential Information

    Online programs in chemistry at the undergraduate level are very uncommon because the study of chemistry requires extensive work in a laboratory. Even though there are limited online options in chemistry, some basic undergraduate chemistry classes may be taken online and certain programs, such as training to become a high school chemistry teacher, are available remotely. Students might also earn a bachelor’s degree in chemical engineering through distance learning. Individuals can find classes in general chemistry, science and technology, biochemistry, laboratory science and organic chemistry.

    Bachelor’s Degree in Chemistry

    An online chemistry program can be designed for someone who has worked in a chemical field and wishes to return to school for teacher certification. Online chemistry classes usually cover a general survey of chemistry and chemistry concepts and may sometimes be used to complete a physical science requirement for another degree.

    Learning Environment

    A bachelor’s degree usually takes four years to complete. Online programs are usually tied to the college’s academic calendar. Some programs are done at the student’s convenience, while others might require the student to be available at a specific time.

    There have been some unique programs where students are encouraged to perform chemical experiments at home using basic household ingredients. Students might have to access videos and conduct sequential experiments. Most chemistry degree programs require multiple math classes, including calculus.

    Common Coursework

    General Chemistry

    This is a survey type class that includes material on topics like atoms and molecules, properties of gases and fundamental concepts of chemistry. Students might be required to do simple experiments at home and report back on what happens using specified measurement techniques.

    Introduction to Biochemistry

    This course covers the chemical aspects of biological processes. Students might learn about the structure of DNA or how glucose is related to diabetes.

    Instrumental Analysis

    In this class, students learn about instrumental methods. Topics like measuring UV light, or magnetic resonance spectroscopy and electrochemistry might be included.

    Analytical Chemistry

    This class introduces students to methods of quantitative analysis. Using instrumental methodologies, students learn the underlying principles of the measurement of chemical substances.

    Career Information for Graduates

    A bachelor’s degree in chemistry provides an education with many different possible career paths. As a rule, for most jobs, the bachelor’s degree is the minimum degree required; in many cases, companies might require a master’s or doctoral degree.

    According to the U.S. Bureau of Labor Statistics (www.bls.gov ), becoming a chemist does not provide a fast-growth career path. It is expected to grow only at the rate of 3% over the 2014-2024 decade. The median annual wage for someone working as a chemist was $71,260 as of May 2015.

    It’s difficult to find undergraduate degrees in chemistry that are available fully online, though some programs might offer a handful of courses via distance education. Alternatives include online chemical engineering bachelor’s degree programs as well as chemistry programs designed to prepare students for teacher certification.

    USC Viterbi School of Engineering faculty awarded multiple MURI grants

    USC Viterbi School of Engineering faculty teams were the recipients of three different 2017 Multidisciplinary University Research Initiative grants (MURI) from the Department of Defense. Research teams from USC Viterbi’s Department of Computer Science, the Ming Hsieh Department of Electrical Engineering, and the Mork Family Department of Chemical Engineering and Materials Sciences will work on a range of research topics, from preventing cyber attacks, to advancing quantum computing, and to the development of improved polymers for energy use and storage.

    The following are the three MURI centers:

    “Cyber Deception through Active Leverage of Adversaries’ Cognition Process”

    Milind Tambe, Helen N. and Emmett H. Jones Professor in Engineering at the University of Southern California and co-founder of USC’s Center for Artificial Intelligence in Society (CAIS), will lead a new MURI on cybersecurity, to combat what researchers have identified as increasingly dangerous cyber threats. To do so, Tambe and a team of researchers from Carnegie Mellon University, Arizona State University, University of Texas (El Paso), University of North Carolina (Chapel Hill) and North Carolina State University will employ “Cyber Inception,” a new approach to cyber attacks. The interdisciplinary approach will leverage research in cognitive modeling, computational game theory, and computer systems to advance innovation in security. Using a multi-pronged approach, the researchers will create a mathematical framework for modeling defenders and attackers in a cyber security environment, create cognitive models of decision-making by attackers and develop prototypes for multi-layered environments that can monitor attacks and develop environments in which it will be impossible for attackers to know what is real and what is deceptive.

    Tambe will be the Principal Investigator on this MURI grant, which received a total of $ 6.2 million in funding. His expertise in security games, multi-agent teamwork, and distributed constraint optimization has been deployed by the US Coast Guard, the Federal Air Marshal Service, and by police departments and airports in Los Angeles County. Tambe’s work has also been utilized by wildlife security organizations. Tambe co-directs the USC Center on AI for Social Good.

    “The Foundations of Interactive Protocols for Quantum Computation and Communications”

    Ben Reichardt, associate professor of Electrical Engineering-Systems at USC Viterbi will spearhead a USC effort to this MURI, through a $1.2 million subcontract on quantum computing. The MURI, led by Caltech, will work on developing scalable protocols to test, control and enable the secure, reliable use of arbitrary quantum devices. This research will develop practical and rigorous techniques for certifying devices with more than 10-20 qubits in both single devices and two or more entangled devices.

    “Physics, Chemistry and Mechanics of Polymer Dielectric Breakdowns”

    Priya Vashishta, Dean’s Professor in the Mork Family Department of Chemical Engineering and Materials Science at USC Viterbi and director of the Collaboratory for Advanced Computing and Simulations; Rajiv Kalia, Professor of Physics and Astronomy Computer Science, Chemical engineering, and Materials Science; and Aiichiro Nakano, Professor of Computer Science, Physics and Astronomy and Chemical Engineering and Materials Science, will support a MURI effort with a $1 million subcontract to understand how polymers can be better tailored to support electric power needs and energy storage. This MURI will be led by the University of Connecticut, with collaborators from Stanford, Purdue and USC. It will seek to understand how to limit degradation of polymers that function as dielectrics (which serve as both insulators and capable of charges within electric power grids). This project will focus on the creation of filed-degraded model materials, multi-scale characterization and modeling, and breakdown phenomenology and complexity.

    The USC investigators will use Non-Adiabatic Quantum Molecular Dynamics Methods to investigate the role of excited electronic states that can be created as a result of large electric fields. Quantum Molecular Dynamics simulations will also be used to explain experimental observations of the creation of excited states and monitor how the energy generated during the electron-hole recombination process can cause bond cleavage and defect formation that result in dielectric breakdown of the material.

    About the USC Viterbi School of Engineering

    Engineering Studies began at the University of Southern California in 1905. Nearly a century later, the Viterbi School of Engineering received a naming gift in 2004 from alumnus Andrew J. Viterbi, inventor of the Viterbi algorithm that is now key to cell phone technology and numerous data applications. Consistently ranked among the top graduate programs in the world, the school enrolls more than 6,500 undergraduate and graduate students, taught by 185 tenured and tenure-track faculty, with 75 endowed chairs and professorships. http://viterbi. usc. edu/
