A sample of oxygen occupies 1.00 L If the temperature remains constant and the pressure on the oxygen is tripled what is the new volume?
0.667
When a fixed sample of gas increases in volume?
Decrease its pressure.
If 3.50 of the unknown compound contained 0.117 of C and 0.233 of H how many moles of oxygen were in the sample?
There should be about 0.117 moles of oxygen in the original sample. Is this for the mastering chemistry online quiz? for universiy?
A Sample of a compound contains 64 g of copper and 16 g of oxygen what is the ratio of mass to copper of oxygen?
?
Which sample of water has the lowest vapor pressure?
400 mL at 20C
What if oxygen is removed from a sample of air as iron rusts what happen to the partial pressure of oxygen in the air?
it decreases
If the temperature is increased What happens to the partial pressure of oxygen in a sample of air?
In a sample of air, an increase in temperature will result in an increase in the partial pressure of oxygen.
If a sample of air that has a total pressure of 150 ATM contains 69 oxygen what is the partial pressure of oxygen found within the air?
The pressure is 103,5 at.
A sample of oxygen gas has a volume of 150 milliliters at 300k if the pressure of the sample is held constant and the temp raised to 600k the new sample will be?
300. mL
A sample of oxygen gas occupies 300.0 mL at 27ºC and atmospheric pressure What volume does it occupy at 150ºC and the same pressure?
423mL
What happens to a fixed sample of gas when its temperature changes?
If a fixed sample of gas has a change of temperature pressure would increase.
A sample of oxygen occupies 1.00 L If the temperature remains constant and the pressure on the oxygen is tripled what is the new volume?
0.667
A sample of oxygen gas occupies 320.0 mL at 27C and atmospheric pressure What volume does it occupy at 120C and the same pressure?
419 mL
How many moles of gas were there in this sample if the vapor pressure of water at 25ºC is 23.8 mm Hg?
0.0113 mol oxygen
How is a sample oxygen different from a sample of a water?
Oxygen is just O and water is H2O
Why is the drop in blood pressure important in exchanging fluids within the capillaries?
It is important because capillaries do most of their work of exchanging gases, oxygen and carbon dioxide, by diffusion, which works best under less pressure. ???That is not quite right. Exchange of gases occurs when there are different concentrations in a given sample and it has nothing to do with pressure. Filtration occurs under different pressure, diffusion happens regardless of pressure.
What state was argon found in?
Argon was found in the gaseous state. A sample of clean air was taken. Then oxygen, carbon dioxide, water, and nitrogen were removed. One unknown gas was still in the sample. This was later determined to be Argon.
