This page provides supplementary chemical data on ethanol. Ethanol, also known as ethyl alcohol or grain alcohol, is a flammable, colorless, slightly toxic chemical compound with a distinctive perfume-like odor, and is the alcohol found in alcoholic beverages. ...
Material Safety Data Sheet
The handling of this chemical may incur notable safety precautions. It is highly recommend that you seek the Material Safety Datasheet (MSDS) for this chemical from a reliable source such as SIRI, and follow its directions. An example MSDS in a US format provides guidance for handling a hazardous substance and information on its composition and properties. ...
Structure and properties The refractive index of a material is the factor by which electromagnetic radiation is slowed down (relative to vacuum) when it travels inside the material. ...
The dielectric constant εr (represented as or K in some cases) is defined as the ratio: where εs is the static permittivity of the material in question, and ε0 is the vacuum permittivity. ...
In chemistry, bond strength is measured between two atoms joined in a chemical bond. ...
In molecular geometry, bond length or bond distance is the distance between two bonded atoms in a molecule. ...
Geometry of the water molecule Molecules have fixed equilibrium geometries--bond lengths and angles--that are dictated by the laws of quantum mechanics. ...
In electrical engineering, the magnetic susceptibility is the degree of magnetization of a material in response to an applied magnetic field. ...
