Host Lisa Van Pay meets with NSF-funded scientists Yang-Shao Horn and Yogi Surendranath at the Massachusetts Institute of Technology as they take on the hydrogen energy challenge.
Officer Tom McCloghry is a cop on the beat, patrolling downtown Columbia, South Carolina to keep the streets safe. And, though it's not so unusual these days to see police on Segways, this one is different. This is a hydrogen hybrid Segway, created with support from the National Science Foundation.
Figure 2.7 (OpenStax, Biology 2e) caption: Bohr diagrams indicate how many electrons fill each principal shell. Group 18 elements (helium, neon, and argon) have a full outer, or valence, shell. A full valence shell is the most stable electron configuration. Elements in other groups have partially filled valence shells and gain or lose electrons to achieve a stable electron configuration.

Figure 2.9 (OpenStax, Biology 2e) caption: Two or more atoms may bond with each other to form a molecule. When two hydrogens and an oxygen share electrons via covalent bonds it forms a water molecule.
Solutions are classified as acidic or basic based on their hydrogen ion concentration relative to pure water. An acidic solution has a higher concentration of hydrogen ions, and a basic solution has a lower concentration of hydrogen ions. Other topics covered include chemical reaction basics, properties of acids and based, acid-base reactions, and other mixtures. Part of the "Chemistry" series.
Sherlock Olmos decides to dig deeper into dark corner of this great house to investigate the suspicious behavior of some chemical elements. The exchange of electrons and the characteristics of hydrogen, fluorine gas, and the noble gases are the primary subjects of his investigation. Part of Chemistry: Solved by Sherlock Olmos Series.
Figure 2.27 (OpenStax, Biology 2e) caption: These functional groups are in many different biological molecules. R, also known as R-group, is an abbreviation for any group in which a carbon or hydrogen atom is attached to the rest of the molecule.
Chemistry is the science of interacting particles and the various states of matter. Developing a better understanding of the atomic model through experiments with gases, scientists discovered the Ideal Gas Law, developed phase diagrams, and learned about the properties of supercritical fluids. Today's chemists are exploring new ways to control the interactions of atoms, with the goal of making better hydrogen-powered cars and new technologies for the long-term, underground storage of carbon dioxide to reduce greenhouse warming. Part of the series Chemistry: Challenges And Solutions.
Explore some properties of water with Petunia and Pinky. It's all about those hydrogen bonds. Terms discussed include adhesion, cohesion, surface tension, and specific heat. Part of "The Amoeba Sisters" series.
Figure 2.15 (OpenStax, Biology 2e) caption: When we mix table salt (NaCl) in water, it forms spheres of hydration around the ions.
Lab experiments demonstrate a variety of ways to detect carbon and hydrogen in organic substances. Burns hexane, benzene, cyclohexane, and naphthalene; shows properties of a propane-butane mixture.
Figure 2.23 (OpenStax, Biology 2e) caption: Carbon can form five- and six-membered rings. Single or double bonds may connect the carbons in the ring, and nitrogen may be substituted for carbon.
Oxygen is the chemical element with the symbol O and atomic number 8. It is a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds.After hydrogen and helium, oxygen is the third-most abundant element in the universe by mass.
Our middle-aged sun has fascinated people throughout history, but only since the rocket age have scientists been able to document its life and the forces that sustain it. Explores sunspots, solar cycles, the birth of a solar storm, and the use of specialized spacecraft outside earth's ionosphere.
Part of the "Chemistry in Action" series. Demonstrates how chemical compounds are placed into groups so that they may be studied easier. Explores acids and bases, emphasizing their nature and common everyday uses. Discusses carbon compounds, and introduces the following terminology: acid, base, pH, salt, carbon, organic, and hydrocarbon.
