### oxide | dioxide:

Chlorine dioxide
* based fires produce other poisonous gases, including chlorine gas.
* can explode easily
  - react with bromide when in sunlight to make bromate
* gas and is very unstable.
* is also an essential ingredient in today's highest-quality pulp and paper products
  - chemical compounds
  - desirable whenever the organic load of the water is high
  - efficient in eliminating microbes for lettuce, cucumber, and beef
  - more expensive than chlorine gas or hypochlorites
  - no exception
  - remarkable, particularly in the way it reacts with organic compounds in wood
* is used as a biocide, a sterilising agent and in water treatment
  - extensively as a bleaching agent in the pulp and paper industry
  - to bleach wood pulp to make paper
* neutralizes the sulfur compounds which cause bad breath.
* proven pollution prevention technology.
* reacts with keratin and splits disulfide bonds.
* transfers an oxygen to the lignin to break up the rings.
* truly remarkable substance.
* very good disinfectant, but it exists as a gas.
+ Bromate: Bromine compounds
  * Bromates are made by reacting bromides with ozone. They can also be made by electrolysis of a hot bromide solution. Chlorine dioxide can react with bromide when in sunlight to make bromate. Bromates can be made by reacting potassium hydroxide with bromine. This makes bromide and bromate. Bromates can be made by reacting bromic acid with a base.
+ Chlorine dioxide, Dangers
  * Chlorine dioxide can explode easily. It is toxic in large amounts
  - How it is made: Chlorine compounds :: Oxides
  * Chlorine dioxide can explode easily. That is why it is normally made when it is needed. It is not normally packaged and sent to people that need it
  - Uses
  * Chlorine dioxide is used to bleach wood pulp to make paper. It can also be used to disinfect water. There are some ways it is better than chlorine

Thorium dioxide
* has the fluorite structure.
* is used for heat resistant ceramics.

Erbium oxide
* adds a pink hue to glasses and porcelain enamel glazes.
* is used in ceramics to obtain a pink glaze
  - produce a pink glaze
  - to color glass and porcelain enamel glazes
* light pink powder in appearance.
* rose-red compound that is slowly soluble in many mineral acids.

Ethylene oxide
* causes tumors in laboratory animals.
* colourless gas which is toxic to inhale.
* is chemical compounds
  - considered to be a potential human carcinogen
  - designated as a hazardous air pollutant
  - extremely flammable
  - gases
  - more volatile than acetaldehyde and water but less volatile than formaldehyde
* is used enormously in the United States for medical supplies and equipment
  - to sterilize medical and other equipment
  - very soluble in water and is flammable

Flint
* are stones.
* is dark gray to black chert and it's found in chalk limestones
* occurs in the form of rounded nodules and is very hard.

### oxide | flint:

Flintstone
* are flints
  - television shows
  - used in some countries for building
* often have a rough lumpy surface but when they are broken , they look like dark glass.
+ Flint, Uses: Sedimentary rocks
  * Flintstones often have a rough lumpy surface but when they are broken, they look like dark glass. It has been one of the most useful types of stone to humankind.
  * Flintstones are used in some countries for building. This gave a better finish to the building that the dull knobbly stones would have made.
