The main classifications of matter include the categories element and compound, either of which may also be called a substance (which is a less specific term), and mixture, of which there are also many sub-categories.Definition of a (Chemical) Mixture:...
An element is a substance that cannot be further broken down into smaller substances by chemical means, such as hydrogen (H). The periodic table of elements lists all discovered elements. A compound is a substance made of two or more elements chemically combined and with a consistent composition...
(Li) and oxygen combine to create lithium oxide (Li2O). Sometimes, a new compound might form when an element is exposed to an existing compound. For example, when pure elemental sodium (Na) is submerged into liquid water (H2O), a reaction occurs, resulting in the formation of sodium ...
Poly(acrylic acid) or PAA (CAS number 9003-1-04) is a type of polymer. The monomer of poly(acrylic acid) is Acrylic Acid. In a water solution at neutral pH, many of the side chains of PAA will lose their protons and acquire a negative charge. For a description of unrelated compound...

Plant roots integrate environmental signals with development using exquisite spatiotemporal control. This is apparent in the deposition of suberin, an apoplastic diffusion barrier, which regulates flow of water, solutes and gases, and is environmentally
The same concept described above can be used to give your shoes a waterproof coating. Spray a bit of WD-40 onto a clean, dry cloth, and buff the outside of your shoes. This will also remove any salt stains you may have gotten during the winter!
On the other hand, the biosynthesis of these compounds is inducible by exposing microalgae to stressful conditions such as high salinity, strong light, nitrogen deprivation, high temperature, short-term UV radiation, or a mixture of these different conditions. Actually, this property of microalgae ...
