### oxide:

Acidic oxide
* Acidic Oxides react with water to form an acid.
* All acidic oxides react with alkalis to give salt and water only.
* Most acidic oxides are soluble in water and react with it giving acids in solution.
* are usually oxides of non-metals.

Boron oxide
* compound of boron and oxygen.
* is giant covalent and is acidic.

### oxide:

Cadmium oxide
* can be a colorless powder , brown powder , or red-brown crystals
  - brown, red, or white
+ Cadmium oxide, Properties: Cadmium compounds :: Oxides
  * Cadmium oxide can be a colorless powder, brown powder, or red-brown crystals. All forms dissolve in acid. It is carcinogenic. Breathing the dust is harmful. It is similar in some ways to zinc oxide.
+ Cadmium, Properties, Chemical compounds: Metals :: Chemical elements
  * Cadmium oxide can be brown, red, or white. Cadmium sulfide is bright yellow. Cadmium chloride and cadmium sulfate are colorless solids that dissolve easily in water. Cadmium fluoride is slightly soluble. Cadmium compounds are toxic when inhaled.

Calcium oxide
* absorbs moisture from the air and expands in size creating paIls or cracks.
* is alkaline
  - bases
  - chemical compounds
  - electrolytes
  - inorganic compounds
  - ionic compounds
* natural form of calcium.
* reacts very exothermically.

Chert
* come in a variety of colors such as red and green.
* is oxide

Cobalt oxide
* is added in very small amounts to glass ingredients to produce the cobalt blue color.
* makes glass turn blue.
* turns glass blue.

Cupric oxide
* can form by oxidation of the cuprous ions.
* is the black flaky stuff that forms.

Cuprous oxide
* is classified as a semiconductor, while cupric oxide is an insulator
  - very well known as a semiconductor
* type of material called a semiconductor.
