Data:
p (pressure) = 81.8 kPa = 81.8*10³ Pa ≈ 8.07 atm
v (volume) = ? (in L)
n (number of mols) = 0.352 mol
R (Gas constant) = 0.082 (atm*L/mol*K)
T (temperature) = 25ºC converting to Kelvin, we have:
TK = TC + 273 → TK = 25 + 273 → TK = 298
Formula:
Solving:
Answer: True
Explanation:
I just took the test and got it right
I found this is the order of activity in Internet
Mn>Zn>Cr>Fe>Cd>Co>Ni>Pb
You can see that Fe is between Cr and Cd
Cr is more active than Fe and Fe is more active than Cd.
The Fe will displace Cd but not Cr.
Answer:Fe
I would say 2 because co2 goes out and o goes in
Answer:
Divers breathe compressed air that contains nitrogen. At higher pressure under water, the nitrogen gas goes into the body's tissues. ... Nitrogen narcosis: Deep dives can cause so much nitrogen to build up in the brain that you can become confused and act as though you've been drinking alcohol.Oxygen becomes rapidly toxic at depth – prolonged exposure to pure oxygen below a few metres can kill you. It is not an appropriate scuba tank gas mixture. ... Oxygen is also highly reactive and can make other substances flammable. Safety training is necessary to work with pure oxygen.

I hope this helped,i m sorry if its not the exact answer you need.
