Answer:
Step-by-step explanation:
9. You know the total pressure of all the gases is 1.0 atm. You also know the partial pressure of two of the gases:
Partial pressure of He = 0.43 atm
Partial pressure of CO₂ = 0.05 atm
Partial pressure of O = x
0.43 atm + 0.05 atm + x = 1.0 atm
0.48 atm + x = 1.0 atm
Subtract 0.48 atm from both sides of the equation.
x = 1.0 atm - 0.48 atm = 0.52 atm
The partial pressure of O is 0.52 atm.
10. You know the total pressure of all the gases is 32.9 atm. You also know the partial pressure of two of the gases:
Partial pressure of O₂ = 6.6 atm
Partial pressure of N₂ = 23 atm
Partial pressure of CO₂ = x
6.6 atm + 23 atm + x = 32.9 atm
29.6 atm + x = 32.9 atm
Subtract 29.6 atm from both sides of the equation.
x = 32.9 atm - 29.6 atm = 3.3 atm
The partial pressure of CO₂ is 3.3 atm.
11. The volume of the balloon decreases due to the increased pressure at that depth.
