Yet another route is the reaction between ammonia and bromine, resulting in the formation of nitrogen and ammonium bromide.
#Obtained from liquid air by fractional distillation free#
In another approach, passing ammonia gas over a hot metallic oxide will result in the formation of free nitrogen, the free metal, and water. The heating of barium or sodium azide (NaN 3 or Ba 2) also yields free nitrogen. For example, a hot aqueous solution of ammonium nitrite decomposes spontaneously to give elemental nitrogen and water. Both an "oxygen-free" form of nitrogen (containing less than two parts per million of oxygen) and an "ultra-pure" nitrogen (containing less than 10 parts per million of argon) are also available commercially.Ī number of methods are available for preparing nitrogen from its compounds in the laboratory on a small scale. Air is a mixture of nitrogen, oxygen, carbon (IV) oxide, noble gases and water vapour.These gases can be obtained by fractional distillation of liquid air. Can you explain this answer? tests, examples and also practice Class 12 tests.This process produces a high-quality product that generally contains less than 20 parts per million of oxygen. than nitrogend)oxygen has a lower density than nitrogen.Correct answer is option 'C'. Can you explain this answer? theory, EduRev gives you anĪmple number of questions to practice It is possible to obtain oxygen from air by fractional distillation because a)oxygen is in a different group of the periodic table from nitrogenb)oxygen is more reactive than nitrogenc)oxygen has higher b.p. Can you explain this answer? has been provided alongside types of It is possible to obtain oxygen from air by fractional distillation because a)oxygen is in a different group of the periodic table from nitrogenb)oxygen is more reactive than nitrogenc)oxygen has higher b.p. Can you explain this answer?, a detailed solution for It is possible to obtain oxygen from air by fractional distillation because a)oxygen is in a different group of the periodic table from nitrogenb)oxygen is more reactive than nitrogenc)oxygen has higher b.p. It is possible to obtain oxygen from air by fractional distillation because a)oxygen is in a different group of the periodic table from nitrogenb)oxygen is more reactive than nitrogenc)oxygen has higher b.p. Oxygen is removed from the mixture by passing it over hot copper. Under the proper conditions, a fraction containing roughly 60 noble gases, 30 oxygen, and 10 nitrogen can be obtained from liquid air. Can you explain this answer? defined & explained in the simplest way possible. The heavier noble gases argon, krypton, and xenon are obtained by the fractional distillation of liquid air. Here you can find the meaning of It is possible to obtain oxygen from air by fractional distillation because a)oxygen is in a different group of the periodic table from nitrogenb)oxygen is more reactive than nitrogenc)oxygen has higher b.p. Can you explain this answer? covers all topics & solutions for ClExam.įind important definitions, questions, meanings, examples, exercises and tests below for It is possible to obtain oxygen from air by fractional distillation because a)oxygen is in a different group of the periodic table from nitrogenb)oxygen is more reactive than nitrogenc)oxygen has higher b.p. In this process, a liquid mixture is divided into fractions by using the.
By using the fractional distillation technique, we can separate several gases from liquid air. It is composed of various concentrations of gases including nitrogen, oxygen, carbon dioxide, argon, and others. than nitrogend)oxygen has a lower density than nitrogen.Correct answer is option 'C'. These gases are produced at premises by mechanical means using gaseous air or the fractional distillation of liquid air. Fractional distillation: Air is a homogenous mixture of gases. Information about It is possible to obtain oxygen from air by fractional distillation because a)oxygen is in a different group of the periodic table from nitrogenb)oxygen is more reactive than nitrogenc)oxygen has higher b.p. The Question and answers have been prepared Can you explain this answer? for Clis part of Class 12 preparation.
