How is ammonia separated in the Haber process?
In the Haber process, ammonia is separated from the unreacted nitrogen and hydrogen gases by compressing the reaction mixture. This causes ammonia, being a soluble gas, to liquefy and separate from the remaining gases. This process helps to increase the concentration of ammonia and improve the overall efficiency of the reaction.
Why ammonia gas liquefies?
Ammonia gas liquefies when it is exposed to high pressure and low temperature. By increasing the pressure and decreasing the temperature, the ammonia gas molecules come closer together, reducing their kinetic energy and causing them to form a liquid state.
Why are some gases heavier than others?
Gases can have different densities due to variations in their molecular weight. Heavier gases have molecules that are larger and/or more massive, leading to a higher density. Additionally, intermolecular forces and temperature can also affect the density of gases.
How is oxygen gas heavier?
Oxygen gas is considered heavier than other gases (like nitrogen and helium) because the oxygen molecule (O2) has a higher molecular weight due to its two oxygen atoms bonded together. This higher molecular weight causes oxygen gas to be denser and therefore heavier than some other gases.
What gases does household ammonia have in it?
Household ammonia primarily consists of water and ammonia gas. Ammonia is a compound made up of nitrogen and hydrogen atoms.

Are at low temperatures ideal gases liquefy?
At low temperatures, ideal gases can liquefy if they are cooled below their critical temperatures. At temperatures below the critical temperature, the gas will condense into a liquid due to the decreased molecular motion and intermolecular forces becoming dominant over kinetic energy.
Is the apparent molecular weight of air at elevation same as at sea level?
The apparent molecular weight of a mixture of ideal gases depends on the concentrations of such gases in the Atmosphere. Below 100km altitude the gases in the atmosphere are very well mixed so that the concentration of all the gases does not vary (approximately) with altitude. Therefore the apparent molecular weight would not vary very much at an elevation and at sea level.
Suggest the method to liquefy atmospheric gases?
evaporation and condensation or just condensation
What is the term for gaseous substances that have been chilled until they liquefy?
They are liquefied gases.
Can you convert the noble gases into liquids?
Yes, you can convert the noble gases into liquids. It is possible to liquefy any gas by cooling it enough.
Does all gases diffuse the same speed?
No, all gases do not diffuse at the same speed. Factors such as molecular weight, temperature, and pressure influence the diffusion rate of gases. Lighter gases tend to diffuse faster than heavier gases.
What is the relationship between the rate of effusion of a gas and its molecular weight, according to the statement that "the rate of effusion of a gas is proportional to" something?
According to Graham's law of effusion, the rate of effusion of a gas is inversely proportional to the square root of its molecular weight. This means that lighter gases will effuse faster than heavier gases.
Why does hydrogen gas diffuses faster than other gases?
The rate of diffusion of a gas is inversely related to the molecular weight of that gas. The lighter the gas, the faster it diffuses. Hydrogen is the lightest of all gases having a molecular weight of only 2. Thus it diffuses faster than all others.
Why molecular weight of air is 28.9?
It is the weighted average of the individual molecular weights of the components oxygen and nitrogen. Generally speaking, air is composed of 21% oxygen and 79% nitrogen. Thus the average molecular weight of air is calculated as follows: MW air = (.21)*(MW O2) + (.79)*(MW N2)
Why are some gases heavier than others?
Gases can have different densities due to variations in their molecular weight. Heavier gases have molecules that are larger and/or more massive, leading to a higher density. Additionally, intermolecular forces and temperature can also affect the density of gases.
