Cobalt(II) hydroxide is a chemical compound. Its chemical formula is Co(OH). It contains cobalt in its +2 oxidation state as an ion. It also contains hydroxide ions. It is either reddish or bluish. It is made by reacting a strong base with a cobalt(II) salt. Cobalt(II) chloride is normally used. This makes the red form. The blue form is made by reacting ammonium hydroxide with cobalt(II) hydroxide. It turns into cobalt(II) oxide when heated. It is used to dry paints, to make other cobalt compounds, and as a catalyst.
Cobalt(III) oxide
Cobalt(III) oxide is a chemical compound. It contains cobalt in its +3 oxidation state. Its chemical formula is CoO. It can be made by reacting a cobalt(II) salt with sodium hypochlorite. This reaction also makes some chlorine. It is used as a catalyst. It is an oxidizing agent. It is not as strong an oxidizing agent as other cobalt(III) compounds.
Cobalt oxide
Cobalt oxide can refer to either of the following:
Cobalt(II) sulfate
Cobalt(II) sulfate, also known as cobaltous sulfate, is a chemical compound. Its chemical formula is CoSO. It contains cobalt in its +2 oxidation state. It contains cobalt and sulfate ions.
It is a reddish crystalline solid. It dissolves easily in water. It is reddish without water (anhydrous) and pink with water (hydrated).
It can be made by reacting cobalt, cobalt(II) oxide, or cobalt(II) hydroxide with sulfuric acid. It is very rarely found in the earth.
It is used as a pigment. It is also used to make other cobalt salts. It can be used in electroplating cobalt. It was added to beer in the past but that poisoned people.
Cobalt(II) sulfate is slightly carcinogenic. It is poisonous in large quantities.
Meccano
Meccano is a building set that lets people make models and small mechanical devices. It was made in 1901, and was from the United Kingdom.
Monoclonius
Monoclonius is the doubtful name of a ceratopsid dinosaur. It was a herbivore (plant-eater) It lived in North America during the Upper Cretaceous, about 76 to 73 million years ago.
"Monoclonius" was named by Edward Drinker Cope in 1876, soon after the first fossil specimen had been found in Montana. The specimen was a near complete skeleton with only the feet missing. It included skull material and the base of the nasal horn. Its name means "single stem" and refers to its teeth, which have a single root.
"Monoclonius" is now regarded as a "nominem dubium". It seems to be a juvenile stage of "Centrosaurus".
Gordini
Gordini is a French sports car manufacturer. The firm was founded by Amédée Gordini. His nickname was "Le Sorcier", which means "The Sorcerer".
Gordini competed in Formula One from 1950 to 1956.
Gordini worked with Renault as an engine tuner. He sold his firm to Renault. Renault entered Renault-Gordini cars at the 24 Hours of Le Mans from 1962 until 1969.
Renault build sport versions of some models like the Dauphine, Renault 8, and Renault 12. They included the Gordini badge.
In November 2009, Renault announced that it will bring back the Gordini name. It will be used on a line of hot hatches (sports compacts).
Popish Plot
The Popish Plot was a story made up by Titus Oates that caused people to hate the Catholics in England between 1678 and 1681. Oates said that there was a large Catholic conspiracy to kill Charles II. His story led to the execution of at least 15 men and caused the Exclusion Bill Crisis. After a while Oates' complicated story fell apart, and he was arrested and sent to prison for perjury.
Cobalt(II,III) oxide
Cobalt(II,III) oxide is a chemical compound. It contains some (1 atom) cobalt in the +2 oxidation state and some (2 atoms) in the +3 oxidation state. Its chemical formula is CoO. It contains cobalt and oxide ions.
It is a black solid. It reacts with hydrochloric acid to make chlorine and cobalt(II) chloride.
It is made when cobalt(II) oxide is heated to . When it is heated to , it turns back into cobalt(II) oxide.
It has been used in research for making hydrogen.
It is irritating to the skin. It can cause harm if swallowed. It dissolves in the stomach acid.
Ramsar Convention
The Ramsar Convention (The Convention on Wetlands of International Importance, especially as Waterfowl Habitat) is an international treaty to protect wetlands. It is meant to stop the loss of wetland areas now and in the future. It recognizes that wetlands are an important ecosystem. It also recognizes that wetlands have economic, cultural, scientific, and recreational value. It is named after the town of Ramsar in Iran.
The convention was developed and agreed to by 18 nations at a meeting in Ramsar on February 2, 1971. It came into force on December 21, 1975.
The Ramsar List of Wetlands of International Importance now includes 1,888 sites, which are called "Ramsar Sites", covering around 1,853,000 km². This has increased from 1,021 sites in 2000. The nation with the most sites is the United Kingdom at 168. The nation with the greatest area of listed wetlands is Canada, with over 130,000 km², including the Queen Maud Gulf Migratory Bird Sanctuary at 62,800 km².
There are now 159 nations that have agreed to the convention. The nations meet every three years as the Conference of the Contracting Parties (COP). The first meeting was held in Cagliari, Italy, in 1980. Changes to the original convention have been agreed to in Paris (1982) and Regina (1987).
There is a standing committee, a scientific review panel, and a secretariat. The headquarters is in Gland, Switzerland, shared with the IUCN.
