Consider a process in which a carbon-based fuel is combusted in the presence of 70% excess oxygen (assume that all of the oxygen present come from an air feel stream). Based on the information given above, which of the following statements are true? Select all that apply.

a. Exactly 70% of the oxygen presence in the process is not consumed.

b. 70% of the fuel in the process undergoes complete combustion.

c. At least 41% of the oxygen present in the grocers is not consumed

d. There is 70% more air present in the process that would be necessary for the complete combustion of all the fuel

e. There is 70% more oxygen present in the process that would be necessary for the complete combustion of all of the fuel

Option - (A):

When a carbon-based fuel is burned (combustion) or we can say burned in the presence of 70% excess oxygen (assuming that all of the oxygen present come from an air feel stream), we can say that there is 70% more oxygen present in the process that would be necessary for the complete combustion of all of the fuel. Oxygen, O₂ is the precursor for the process of combustion as there is the requirement of an optimum level of oxygen for the burning up of the materials. While, there is about enough level of oxygen is present inside the free air or we can say inside the atmosphere for the purpose of combustion or burning of the fuel or consumption of the resources present in the environment.
