What is the mole fraction of oxygen in a gas mixture that is 37 percent oxygen and 63 percent nitrogen in volume?
To find the mole fraction of oxygen, first convert the percentages to fractions: 37% oxygen is 0.37 and 63% nitrogen is 0.63. Since the total mole fraction in a mixture is 1, the mole fraction of oxygen would be 0.37/(0.37 + 0.63) = 0.37/1 = 0.37. Therefore, the mole fraction of oxygen in the gas mixture is 0.37.
Where would you find 79 percent nitrogen 16 percent oxygen 4.5 percent carbon dioxide?
Those percentages closely match the composition of Earth's atmosphere at sea level. The atmosphere is made up of mostly nitrogen (around 78%) and oxygen (around 21%), with trace amounts of other gases like carbon dioxide (around 0.04%).
Air is about 78.0 percent nitrogen molecules and 21.0 percent oxygen molecules Several other gases make up the remaining 1 percent of air moleculesWhat is the partial pressure of nitrogen in air at at?
The partial pressure of nitrogen in air at sea level (assuming total pressure of 1 atm) would be 0.78 atm, calculated as 0.78 (78% of the total pressure).
What would happen to something burning if there was only oxygen and no nitrogen?
If there was only oxygen and no nitrogen present, the burning process would be more efficient and the flames would burn brighter and hotter. Nitrogen in the air can act as a diluent, which can dampen the combustion process.
What information would you need in order to convert molarity to percent by volume?
To convert molarity to percent by volume, you would need to know the molar mass of the solute and the density of the solution. With these values, you can calculate the volume of the solute in a given volume of the solution to determine the percent by volume.
Which would be a solute 80 percent of nitrogen or 20 percent oxygen?
none of them are solutes
How would life be different if there was 80 percent oxygen and 20 percent nitrogen?
The atmosphere would be much more volatile.
What 2 elements make-up approximately 99 percent of the Earth's atmosphere?
Nitrogen (78%) and Oxygen (21%) are the two main elements that make up approximately 99% of the Earth's atmosphere.
What is the mole fraction of oxygen in a gas mixture that is 37 percent oxygen and 63 percent nitrogen in volume?
To find the mole fraction of oxygen, first convert the percentages to fractions: 37% oxygen is 0.37 and 63% nitrogen is 0.63. Since the total mole fraction in a mixture is 1, the mole fraction of oxygen would be 0.37/(0.37 + 0.63) = 0.37/1 = 0.37. Therefore, the mole fraction of oxygen in the gas mixture is 0.37.
Is nitrogen important for survival?
without nitrogen our bodys would over oxygenate (get to much oxygen). nitrogen is important for plants, after all they breath in nitrogen and breath out oxygen.

What is the more important the oxygen or the nitrogen?
umm oxygen. we would die without it
What element is contained in proteins?
That answer would be carbon Sources: Biology teacher.
What would be a list of Atmosphere?
nitrogen, oxygen, and argon
What chemical element would you expect to find in amino acids?
*amino acids include 16 percent of nitrogen , I think it's include : carbon , hydrogen , oxygen , and nitrogen *
Why do we need nitrogen i the atmosphere?
Without nitrogen in the atmosphere, we would be breathing in nearly pure oxygen, which would be fatal.
What formula would two Nitrogen atoms and one Oxygen atom make up?
The combination of two nitrogen atoms and one oxygen atom would form a molecule of nitrogen dioxide (NO2). This is because nitrogen typically forms a double bond with oxygen in this configuration.
