This naturally occurring chemical compound - Carbon dioxide (CO2) - is a colourless, non-toxic gas having a faint, sharp odour and a sour taste. The gas composed of one carbon atom and two oxygen atoms. Carbon dioxide is used commercially in fire extinguishers and to carbonate beverages. The gas freezes solid at minus 56°C and is known as "dry ice" in that state. At ordinary temperatures, carbon dioxide is quite unreactive; but above 1,700 °C it partially decomposes into carbon monoxide and oxygen.
While carbon dioxide occurs naturally, and is a minor component of Earth’s atmosphere (about 3 volumes in 10,000), formed in combustion of carbon-containing materials, in fermentation, and in respiration of animals and employed by plants in the photosynthesis of carbohydrates. The presence of the gas in the atmosphere keeps some of the radiant energy received by Earth from being returned to space, thus producing the so-called greenhouse effect. It is the most common of the man-made greenhouse gases and is believed to be a significant contributor to global warming.
Carbon Monoxide (CO) is a colourless, odourless poisonous gas consisting of one carbon atom and one oxygen atom and is a common yet preventable cause of death from poisoning worldwide. Approximately half of the deaths from unintentional CO poisonings result from the inhalation of smoke from fires. Other significant causes are vehicle exhausts and deaths in industrial / commercial settings.
The incomplete combustion of organic fossil fuels such as oil, gas or coal is a common environmental source of CO and is responsible for many cases of non-fatal unintentional CO poisoning. It forms when there is not enough oxygen to produce carbon dioxide (CO2), such as when operating a coal fire stove or an internal combustion engine in an enclosed space. It can be ignited in the presence of oxygen, and the gas burns with a blue flame producing carbon dioxide.
When CO is inhaled into the body it combines with the blood, preventing it from absorbing oxygen. If a person is exposed to CO over a period, it can cause illness and even death.
Carbon Monoxide has no smell, taste or colour. This is why it is known the "Silent Killer".
