What is the partial pressure of oxygen if the partial pressures of the nitrogen and carbon dioxide are 100 kPA and 24 kPa respectively?
To find the partial pressure of oxygen, you can use Dalton's Law of Partial Pressures, which states that the total pressure is the sum of the partial pressures of all gases in a mixture. Assuming the total pressure is the sum of the given partial pressures, you can calculate it as follows: Total Pressure = Partial Pressure of Nitrogen + Partial Pressure of Carbon Dioxide + Partial Pressure of Oxygen. If we denote the partial pressure of oxygen as ( P_O ): Total Pressure = 100 kPa + 24 kPa + ( P_O ). Without the total pressure, we cannot determine the exact value of the partial pressure of oxygen. However, if the total pressure is known, you can rearrange the equation to solve for ( P_O ) as ( P_O = \text{Total Pressure} - 124 kPa ).
What are the 6 most abundant elements in the biosphere?
Carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur.
Could nitrogen oxygen and hydrogen occur together in mixture of liquids?
Yes, nitrogen, oxygen, and hydrogen can all exist together in a mixture of liquids. These gases can dissolve in liquids to varying degrees depending on factors like temperature and pressure. For example, nitrogen and oxygen are more soluble in water compared to hydrogen.
Why hydrogen gas is liquefied first than helium gas?
Hydrogen gas is liquefied first than helium gas because hydrogen has a higher critical temperature and pressure than helium. This means that hydrogen can be liquefied at higher temperatures and pressures compared to helium. Helium requires lower temperatures and pressures to be liquefied, making it more challenging to achieve compared to hydrogen.
What are Pressures less then 0 KPa are called?
Pressures less than 0 kPa are called negative pressures. They indicate a pressure lower than atmospheric pressure.
. A mixture of oxygen hydrogen and nitrogen gases exerts a total pressure of 282 kPa. If the partial pressures of oxygen and hydrogen are 110 kPa and 106 kPa respectively what is the partial pressure?
Total pressure = ppO2 + ppH2 + ppN2ppN2 = Total pressure - (ppO2 + ppH2)ppN2 = 282 kPa - (110+106 kPa) = 282kPa - 216kPappN2 = 66 kPa = partial pressure of nitrogen
A box with a volume of 22.4 L contains 1.0 mol nitrogen and 2.0 mol hydrogen at 0à Celsius Which of the following statements is true?
The statement that is true is: The partial pressure of nitrogen is equal to the partial pressure of hydrogen in the box. This is because both nitrogen and hydrogen behave ideally and occupy the same volume, so their partial pressures are directly proportional to their mole quantities in the box.

What does Hydrogen and Nitrogen react to form?
Hydrogen and nitrogen react to form ammonia (NH3) in the presence of a catalyst at high temperature and pressure.
What are the three elements that exist as a gas at room temperature and pressure?
Hydrogen, nitrogen, oxygen, fluorine, chlorine, and all the noble gases exist as a gas at standard temperature and pressure.
What is hydrogen' s state of matter?
Hydrogen can exist in different states of matter depending on the temperature and pressure. At room temperature and pressure, hydrogen is a gas. However, at very low temperatures, hydrogen can become a liquid, and at extremely high pressures, it can solidify into a metallic state.
What is the atmospheric pressure if the partial pressure of nitrogen oxygen and argon are 442mm Hg 118.34mm Hg and 5.66mm Hg respectively?
These three components are the three largest components of air. The total pressure of a gas mixture is just the sum of the partial pressures of each component. Air is a mixture and nitrogen, oxygen, and argon are the three biggest components. So, the atmospheric pressure (or air pressure) would be the sum of the partial pressure of each component of the air: Ptot=PPnitrogen + PPoxygen+ PPargon = 442 mmHg + 118.34 mmHg + 5.66 mmHg = 566 mmHg
Can you conclude that hydrogen and nitrogen dissolue in water?
Yes, hydrogen and nitrogen can dissolve in water to some extent. However, hydrogen is less soluble than nitrogen, with nitrogen being more soluble due to its ability to form hydrogen bonds with water molecules. The solubility of both gases in water can be affected by various factors such as temperature and pressure.
What is the chemical formula when nitrogen gas reacts with hydrogen gas?
Nitrogen and hydrogen react to form ammonia. This is the reaction in the Haber process, in which the gases are mixed at high pressure and moderately high temperature and passed over an iron catalyst.
What are the 6 most abundant elements in the biosphere?
Carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur.
What if you mix Hydrogen and nitrogen?
If hydrogen and nitrogen are mixed together, they will not react at room temperature and pressure because hydrogen is relatively unreactive towards nitrogen. However, under certain conditions such as in the presence of a catalyst and at high temperatures, they can react to form ammonia in a process called Haber-Bosch synthesis.
What are elements composed of compounds atoms mixtures or molecules?
At sufficiently high temperatures and low pressures, all elements are composed of atoms. At standard temperature and pressure, some elements are composed of molecules, usually diatomic molecules, as with nitrogen, hydrogen, oxygen, and all the halogens.
