Explanation:
.
Among the four species in this reaction, is species with the largest number of atoms per molecule. Assume that the coefficient of this compound is
.
.
Number of atoms on the left-hand side of the reaction:
:
.
:
.
: not found yet.
By the conservation of atoms, the number of atoms on the right-hand side of the reaction should match those on the left-hand side. In this reaction, is the only product with carbon atoms, whereas
is the only product with hydrogen atoms. These
carbon atoms and
hydrogen atoms would correspond to:
molecules, and
molecules.

Answer:
Explanation:
The air 9% mole% methane have an average molecular weight of:
9%×16,04g/mol + 91%×29g/mol = 27,8g/mol
And a flow of 700000g/h÷27,8g/mol = 25180 mol/h
In the reactor where methane solution and air are mixed:
In = Out
Air balance:
91% air×25180 mol/h + 100% air×X = 95%air×(X+25180)
Where X is the flow rate of air in mol/h = <em>20144 mol air/h</em>
<em></em>
The air in the product gas is
95%×(20144 + 25180) mol/h = 43058 mol air× 21%O₂ = 9042 mol O₂ ×32g/mol = <em>289 kg O₂</em>
43058 mol air×29g/mol <em>1249 kg air</em>
Percent of oxygen is: =<em>0,231 kg O₂/ kg air</em>
<em></em>
