Chemistry Glossary: Search results for ''legiranje''

Calcium was discovered by Sir Humphry Davy (England) in 1808. The origin of the name comes from the Latin word calix meaning lime. It is fairly hard, silvery-white metal. Exposed surfaces form oxides and nitrides. Reacts with water and oxygen. Occurs only in compounds. Calcium is obtained from minerals like chalk, limestone and marble.

Acidic oxide - Howling Pixel

Acidic oxide. Acidic oxides, or acid anhydrides, are oxides that react with water to form an acid, or with a base to form a salt.They are oxides of either nonmetals or of metals in high oxidation states.Their chemistry can be systematically understood by taking an oxoacid and removing water from it, until only an oxide remains. The resulting oxide belongs to this group of substances.
