Calcium - Compounds | Britannica

Calcium oxide, CaO, also known as lime or more specifically quicklime, is a white or grayish white solid produced in large quantities by roasting calcium carbonate so as to drive off carbon dioxide. At room temperature, CaO will spontaneously absorb carbon dioxide from the atmosphere, reversing the reaction.

Metallic Character Properties and Trends

02.05.2021· Metallic character is the set of properties associated with metals. These properties include metallic luster, formation of ions, high electrical and thermal conductivity, and malleability. Metallic character is a periodic table trend. The elements with the most metallic character are on the left side of the periodic table (except hydrogen).

Solubility Rules Chemistry Tutorial

21.06.2011· Solubility Rules as a Table. If you need to memorise the solubility rules for ionic compounds in water at 25°C, then the list above is useful. However, all that information can be placed in a table as shown below, which makes it easier to loe solubility information for a particular ionic compound made up of a particular ion and a particular anion.

Drying agents

21.03.2016· In those cases, drying agents like calcium hydride (CaH 2), sodium metal (in coination with benzophenone) or lithium aluminum hydride (LiAlH 4) are used to chemically destroy the water in the solvent. Those compounds are relatively reactive and difficult to handle and usually not used in lower division undergraduate laboratories (see below).

What is Agent Orange? - The Aspen Institute

Agent Orange was a herbicide mixture used by the U.S. military during the Vietnam War. Much of it contained a dangerous chemical contaminant called dioxin. Production of Agent Orange ended in the 1970s and is no longer in use. The dioxin contaminant however continues to have harmful impact today. As many U.S.Vietnam-era veterans know, dioxin is a highly toxic and …
