2 How CO is Produced Carbon monoxide is produced by the incomplete combustion of fuels. This occurs when there is not enough oxygen mixed with fuel. This is commonly referred to as a "rich mixture". All fuel burning appli- ances have the potential to produce CO in varying concentrations. ...
Diamond is an allotrope of carbon, same substance with different atom configuration. Atoms in diamond form a strong bond in the shape of tetrahedron, resulting in a very strong substance. Graphite is another allotrope of carbon, but atoms are bonded in a different way, it is more of a plana...
Carbon monoxide is generated strictly as a result of incomplete combustion; therefore, when there is no combustion in the first place, there is zero chance of having any form of CO poisoning. This makes the turning-off of the furnace the ideal action to carry out on the discovery of CO le...
The result is anemic hypoxia, which can be observed in cases of both acute and chronic anemia. Patients may need transfusions as well as other treatment to address the underlying cause of the anemia. Another potential cause of this condition is carbon monoxide poisoning. In patients who have ...
Determine the enthalpy for the partial combustion of methane to carbon monoxide- 2CH_4(g) + 3O_2(g) to 2CO(g) + 4H_2O(l) from change in enthalpy (CH_4, g) = -890 kJ mol^{-1} and change in enthalpy (CO What is the enthalpy of formation of carbon ...
The second catalyst type is an oxidisation catalyst which uses Platinum and Palladium to complete the job. These catalysts oxidise or burn the carbon monoxide and hydrocarbons lingering within the incoming gas, helping reduce the amount of smog produced by evaporated, unburnt fuel. ...
