Chromatography is an important biophysical technique that enables the separation, identification, and purification of the components of a mixture for qualitative and quantitative analysis. Proteins can be purified based on characteristics such as size and shape, total charge, hydrophobic groups …
Ionic bonding does give rise to crystal lattices, but it is not the only way a crystal formed. From the mentioned examples, only salt (NaCl) is an ionic crystal, whereas ice stabilized by hydrogen bonds and diamond by covalent bonds …
Although ac electric power is produced at relatively low voltages, it is sent through transmission lines at very high voltages (as high as 500 kV). The same power can be transmitted at different voltages because power is the product IrmsVrms. …
Human anatomy is the scientific study of the body’s structures. Some of these structures are very small and can only be observed and analyzed with the assistance of a microscope. Other larger structures can readily be seen, manipulated, measured, and …
The standard free energy change of a process, ΔG°, was defined as the maximum work that could be performed by a system, Wmax. In the case of a redox reaction taking place within a galvanic cell under standard state conditions, …
Magnetic field lines have several hard-and-fast rules: The direction of the magnetic field is tangent to the field line at any point in space. A small compass will point in the direction of the field line. 500 Chapter 11 | …
What Is Metabolism? Metabolism is the chemical reaction in the body’s cells that change food into energy. Our bodies need this energy to do everything from moving to thinking to growing. Specific proteins in the body control the chemical reactions …
A fuel cell is a galvanic cell that uses traditional combustive fuels, most often hydrogen or methane, that is continuously fed into the cell along with an oxidant. (An alternative, but not very popular, the name for a fuel cell …
Materials are classified as paramagnetic, diamagnetic, or ferromagnetic, depending on how they behave in an applied magnetic field. • Paramagnetic materials have partial alignment of their magnetic dipoles with an applied magnetic field. It has a positive magnetic susceptibility. Only …
The digestive system is one of the largest organ systems in the human body. It is responsible for processing ingested food and liquids. The cells of the human body all require a wide array of chemicals to support their metabolic …
