Final answer:
To find the partial pressure of the remaining air in a blast furnace, we subtract the known partial pressures of carbon dioxide and hydrogen sulfide from the total air pressure. Using Dalton's Law of Partial Pressures, the partial pressure of the remaining air is calculated to be 0.92 atm.
Step-by-step explanation:
The question involves calculating the partial pressure of remaining air in a blast furnace given the total air pressure and the partial pressures of carbon dioxide and hydrogen sulfide. This calculation can be done using Dalton's Law of Partial Pressures, which states that the total pressure of a mixture of gases is the sum of their individual partial pressures. To find the partial pressure of the remaining air, we subtract the sum of the known partial pressures (carbon dioxide and hydrogen sulfide) from the total pressure.
So, the calculation is as follows:
- Total air pressure = 0.99 atm
- Partial pressure of carbon dioxide (CO2) = 0.05 atm
- Partial pressure of hydrogen sulfide (H2S) = 0.02 atm
- Partial pressure of remaining air = Total air pressure - (Partial pressure of CO2 + Partial pressure of H2S)
- Partial pressure of remaining air = 0.99 atm - (0.05 atm + 0.02 atm)
- Partial pressure of remaining air = 0.99 atm - 0.07 atm
- Partial pressure of remaining air = 0.92 atm
The correct answer is b. 0.92 atm.
