Carbon monoxide [yī yǎng huà tàn] Wikipedia card monoxide (carbon monoxide, CO) pure colorless,
kevin durant beats by dre, odorless, non-irritating gases. Molecular weight 28.01, density of 1.250g / l, the freezing point of -207 ℃, boiling point -190 ℃. Low solubility in water. Air mixture explosion limit is 12.5% ~ 74%. Carbon monoxide enters the body after the Council and the hemoglobin in the blood, thereby enabling the hemoglobin can combine with oxygen, causing the body tissue hypoxia,
knock off under armour sunglasses, causes the body to suffocation. Therefore, carbon monoxide is toxic. Carbon monoxide is a colorless, odorless, tasteless gas,
quad lens sunglasses, it is easy to ignore caused the poisoning. Common in the family room with poor ventilation in the case,
quad lens sunglasses, or liquefied gas stoves produce industrial production pipeline leak or carbon monoxide gas and mine inhalation caused poisoning.

Preparation of carbon monoxide is the earliest French chemist de Lassone (in 1776). He by heating zinc oxide and carbon monoxide were prepared. However, due to the combustion of carbon monoxide and hydrogen produced similar blue flame, de Lassone mistakenly believe that he is prepared hydrogen. In 1800 the British chemist William Cruikshank was proved by the carbon monoxide and oxygen elements of the compound. The earliest toxic carbon monoxide thorough study of the French physiologist Claude Bernard. In 1846, he let the dog inhalation of this gas and found the dog's blood "becomes larger than any of the blood in the arteries should be bright red." In recent years we know that blood becomes "Red Cherry" are peculiar to carbon monoxide poisoning symptoms. Because carbon monoxide can become very red blood characteristics, some of the meat processing meat with carbon monoxide traders can make the meat color is not oxidized even at a temperature of 10 ℃ stored 28 days slaughtered meat is also as good as new, and therefore caused criticism. Consumer Federation of America that no harm even if this treatment will cover the meat is not fresh state,
cheap under armour sunglasses, even if the meat is rotten about the state, consumers are unaware of this. Edit this paragraph electronic and structural nature of the outermost layer of carbon four electrons,
16 dollar oakleys, oxygen has six outermost electrons, such carbon into two single-electron orbit of oxygen and the oxygen p-electron pair into two key, so that the formation of two keys, and the lone electron pair of oxygen into carbon empty P forms a track with key, so that oxygen and carbon is formed between the three keys. The electron is:
