Answer:
OB) 1.0 atm
Explanation:
we have a mixture of hydrogen, nitrogen and methane and we have the following data
According to the law of Dalton the sum of the partial pressures of each gas is equal to the total pressure
Total pressure equation
now we clear the partial pressure of nitrogen from the equation
the partial pressure of nitrogen is 1 atm
the correct answer is OB) 1.0 atm

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>
