The term monoxide is used to name a compound having one oxygen atom bonded to another element. Hence, the term dioxide expresses the presence of two oxygen atoms. Some elements form oxides with more than two oxygen atoms. The key difference between monoxide and dioxide is that monoxide compounds contain one oxygen atom bonded to another element whereas dioxide compounds contain two oxygen atoms bonded to the same atom of a different element.
Overview and Key Difference 2. What is Monoxide 3. What is Dioxide 4. The term monoxide is used to name compounds containing one oxygen atom bonded to another element.
However, in monoxide compounds, the only oxygen atom can be bonded to one atom of the other element or two atoms of it, but not more than two. That is because oxygen atom can form only two covalent bonds in its stable condition. But the oxide anion have -2 oxidation state. Then, the monoxide of group 1 elements have two atoms bonded to the same oxygen atom.
Then, one oxygen atom binds to one atom of group 2 element to form the monoxide. It is a largely non-reactive gas, and once released, it quickly mixes throughout the atmosphere. Carbon dioxide is also produced through industrial processes. Industrial plants that produce hydrogen or ammonia from natural gas, coal, or large-volume fermentation operations are some of the largest commercial producers of carbon dioxide.
Carbon dioxide has many applications in the food and beverage industry , including carbonating drinks. Carbon monoxide , on the other hand, is the result of incomplete combustion. Unlike carbon dioxide, carbon monoxide does not occur naturally in the atmosphere. It is created through the incomplete combustion of coal, natural gas, and oil.
Low levels of oxygen and low temperatures lead to carbon monoxide in the combustion mixture. Dangerous levels of carbon monoxide can be produced by any fuel-burning appliance, including gas furnaces, gas stoves, gas dryers, gas water heaters, fireplaces, and cars.
In industrial settings, the internal combustion engine is the chief source of carbon monoxide. Many furnaces and ovens produce large amounts of the gas, especially when they are not maintained properly.
Truck drivers, forklift operators, or people working near this type of equipment are at a higher risk of exposure. Workers near or within enclosed areas or confined spaces such as manholes, garages, tunnels, loading docks, warehouses, vehicle repair shops, and splicing vehicles are also at risk. While carbon monoxide is usually an unwanted by-product, packaged carbon monoxide is used in a variety of industries including metal fabrication, chemical manufacturing, pharmaceuticals, electronic and semiconductor applications, and for reducing ores when manufacturing metal carbonyls.
Even a Google search for "carbon dioxide" brings up more carbon monoxide awareness websites than we would like to see. Both of these gases have a lot of similarities — both CO 2 and CO are odourless and tasteless. Elevated levels of both gases can cause health problems and even death. The critical chemical difference is that CO 2 contains one atom of carbon and two atoms of oxygen, whilst CO has one carbon and one oxygen atom.
Carbon dioxide naturally occurs in the atmosphere at about parts per million — humans and animals breathe in oxygen and exhale carbon dioxide — we can tolerate a small amount of it.
