How much oxygen do you use while sleeping?
well to calculate this you need to know the lung capacity of the person your are basing your data off of. the amount of oxeygen in the air is about 15.35% and the rest is made up of all sorts of other gases and gas compounds. since sleeping uses the same proccesses as being awake minus the motor functions. this means that the ammount of air, or the ammount of oxeygen used, is equal to the ammount of air used for a stationary or non moving person. there are way too many variables for this equations and is to hard to draw up from scratch. you can use the air capacity postulate and remove the vaccum variable. 3(x)+mass=constant+apmospheric pressure+volume after you balance that out use 2.345485635656 X10(9)-oxeygen percentage (around 15%) and thats it Just plug in your values and the answer comes right out.
How old do you have to be to go to an oxygen bar?
You can be any age, they have one at the mall by my house and they let anyone do it. Oh, if it's attached to a hookah bar then you probably have to be 18 to get in depending on where you live.
Does oxygen get you high? Why or why not?
Oxygen doesn't get you high. not in the same way that other drugs do. High flow oxygen can make you relaxed, and does tend to reduce pain, but here again not to the same degree that other drugs do. Its not hugely effective as anything but what it is oxygen, you give it to people who are having trouble getting air, they have to work less hard to breathe because your increasing the amount of oxygen they breathe from 21% on room air to between 24-36% on a nasal cannula and up to 100% with a non re breathing mask. @River 100% oxygen won't kill you. It's not good long term but I give people 100% oxygen every day and haven't lost anyone yet (from the oxygen anyhow)
Suppose you collected oxygen...?
http://home.comcast.net/~frankhanson2/va... relates that at 25 Celsius, the water vapor has a partial pressure of 23.8 Torr Dalton's law says that the total pressure = sum of the partial pressures 750.5 Torr = (partial pressure of O2) + (partial pressure of H2O) 750.5 Torr = (partial pressure of O2) + (23.8 Torr) partial pressure of O2 = 750.5 Torr - (23.8 Torr) partial pressure of O2 = 726.7 Torr -=====================================... P1V1 & T1 = 745 torr, 3520 L & 28.5 Degrees C(301.5 Kelvin) P2V2 & T2 = 250 torr, ? L , & -25 Degrees C (248 Kelvin) P1V1T2 = P2V2T1 V2 = P1V1T2 / P2T1 V2 = (745 Torr) (3520L) (248K) / (250Torr) (301.5 K) V2 = 8628 Litres
What volume of oxygen do you breathe each day?
The oxidizing agent our bodies use to obtain energy from food is oxygen (from the air). If you breathe 15 times a minute (at rest), taking in and exhaling 0.5 L of air with each breath, what volume of air do you breathe each day? Air is 21% oxygen by volume. What volume of oxygen do you breathe each day
What happens to water if you take the Oxygen out?
Take the oxygen out of the molecule? Like H2O? It become hydrogen gas, H2. This is called Electrolysis. To take dissolved oxygen out of water makes the water stagnant and anything that lives in the water requiring oxygen would die.
There's 21% oxygen in air. When we breathe out, there's still 16% oxygen in the exhaled air. Why are our lungs so inefficient?
Oh, that’s not inefficient at all. In fact, it’s quite the opposite.Here are a few things that will convince you —Even with 16% oxygen being exhaled, the blood (or hemoglobin to be precise) is 100% saturated with oxygen. So, if you think about it, the body is absorbing ALL the oxygen it needs per breath to the best of its ability in a fraction of a second. That’s impressive.That 16% oxygen is a back up for worst case scenarios. Imagine you’re sleeping with a blanket over your head with no supply of fresh air. Or, holding your breath as you swim from one end of the pool to another. Or, the worse, someone is strangulating and smothering you to death —the 16% oxygen is going to save your life. It’s like a Stepney to your flat tire.We exhale 16% oxygen not because of lung inefficiency but because not all portions of the lungs participate in gas exchange. The nose, the mouth, the windpipe, for example, are the conducting portions of airways that do not participate in oxygen-carbon dioxide exchange. They simply transport air from the atmosphere to inside lungs. The functional portions of lungs are the distal-most air sacs called the alveoli where gas exchange occurs.Therefore, when we breathe out, the air from the nose/mouth/windpipe still holds all its oxygen and thus, accounts for the 16% of expired oxygen.It’s like having a savings account — you have a reserve, you do not use all the money every month, but that does not in any way mean that your spending habits are inefficient. :)
Calculate volume of oxygen you would need, at 1 atm and 298 k to completely oxidize 5g of glucose?
... find moles of glucose 5g / 180g/mol = 0.02778 mol find moles of O2 needed . . C6H12O6 + . . 6O2 → 6CO2 + 6H2O 0.02778mol . . . . 0.1667mol convert to liters PV = n R T 1 V = 0.1667 (0.0821) (298) V = 4.08 L depending on your rounding it might come out as 4.09 L When you get a good response, please consider giving a best answer. This is the only reward we get. You may have to wait an hour to award BA.
