Calcium hydride - Wikipedia

2019-5-4 · Calcium hydride is a relatively mild desiccant and, compared to molecular sieves, probably inefficient. Its use is safer than more reactive agents such as sodium metal or sodium-potassium alloy. Calcium hydride is widely used as a desiccant for basic solvents such as amines and pyridine. It is also used to dry alcohols.

Oxides and peroxides - ChemicalBook

Some oxides such as carbon monoxide (CO), nitric oxide (NO), etc., are known as neutral oxides for they react neither with an acid nor with a base. Oxides are widely distributed in nature, such carbon dioxide in the air and silicon dioxide (SiO2), the main component of quartz sand.

Calcium - Wikipedia

2019-5-4 · Calcium is a chemical element with syol Ca and atomic nuer 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air.Its physical and chemical properties are most similar to its heavier homologues strontium and barium.It is the fifth most abundant element in Earth''s crust and the third most abundant metal, after iron and aluminium.

Oxide | chemical compound | Britannica

Oxides of the transition metals with oxidation nuers of +1, +2, and +3 are ionic compounds consisting of metal ions and oxide ions. Those transition metal oxides with oxidation nuers +4, +5, +6, and +7 behave as covalent compounds containing covalent metal-oxygen bonds. As a general rule, the ionic transition metal oxides are basic.

Oxide - Wikipedia

2019-5-15 · An oxide /ˈɒksaɪd/ is a chemical compound that contains at least one oxygen atom and one other element[1] in its chemical formula. "Oxide" itself is the dianion of oxygen, an O2– atom. Metal oxides thus typically contain an anion of oxygen in the oxidation state of −2. Most of the Earth''s crust consists of solid oxides, the result of
