Carbon monoxide (chemical formula CO) is a poisonous, flammable gas that is colorless, odorless, tasteless, and slightly less dense than air. Carbon monoxide consists of one carbon atom and one oxygen atom connected by a triple bond. It is the simplest carbon oxide. In coordination complexes, the carbon monoxide ligand is called carbonyl. It is ...
Gas properties Std enthalpy change of formation, Δ f H o gas: −110.53 kJ/mol Std enthalpy change of combustion, Δ c H o gas: −283.0 kJ/mol Standard molar entropy, S o gas: 197.66 J/(mol K) Heat capacity, c p: 29 J/(mol K)
For a fuel of composition C c H h O o N n, the (higher) heat of combustion is 419 kJ/mol × (c + 0.3 h − 0.5 o) usually to a good approximation (±3%), [2] [3] though it gives poor results for some compounds such as (gaseous) formaldehyde and carbon monoxide, and can be significantly off if o + n > c, such as for glycerine dinitrate, C 3 H 6 ...
The largest part of most combustion gas is nitrogen (N 2), water vapor (H 2 O) (except with pure-carbon fuels), and carbon dioxide (CO 2) (except for fuels without carbon); these are not toxic or noxious (although water vapor and carbon dioxide are greenhouse gases that contribute to climate change).
Syngas produced by coal gasification generally is a mixture of 30 to 60% carbon monoxide, 25 to 30% hydrogen, 5 to 15% carbon dioxide, and 0 to 5% methane. It also contains lesser amount of other gases. [10] Syngas has less than half the energy density of natural gas. [11]
Iron carbonyl is stable as iron pentacarbonyl, where five carbon monoxide molecules are pendently bonded to the iron atom, while nickel carbonyl is stable as nickel tetracarbonyl, which has four carbon monoxide molecules pendantly bonded [jargon] to the nickel atom. Both can be formed by the exposure of the powdered metal to carbon monoxide gas ...
vapour density = molar mass of gas / molar mass of H 2 vapour density = molar mass of gas / 2.01568 vapour density = 1 ⁄ 2 × molar mass (and thus: molar mass = ~2 × vapour density) For example, vapour density of mixture of NO 2 and N 2 O 4 is 38.3. Vapour density is a dimensionless quantity. Vapour density = density of gas / density of ...
Quite often, the flue gas refers to the combustion exhaust gas produced at power plants.Its composition depends on what is being burned, but it will usually consist of mostly nitrogen (typically more than two-thirds) derived from the combustion of air, carbon dioxide (CO 2), and water vapor as well as excess oxygen (also derived from the combustion air).
