Chapter 22: Problem 14

Suggest a physical method that would enable you to separate hydrogen gas from neon gas.

Short Answer

Expert verified
The physical method that can be used to separate hydrogen gas from neon gas is 'Gaseous Diffusion' since hydrogen has a lower molecular weight than Neon.

Step by step solution

01

Identify the properties of hydrogen and neon gases

Hydrogen (H₂) is a molecule made up of two hydrogen atoms, while Neon (Ne) is a noble gas that exists as single atoms. Hydrogen has a lower molecular weight than Neon.
02

Think of a method that could exploit these properties

Based on their molecular weight differences, one feasible method will be to use 'Gaseous Diffusion'.
03

Explain the process of Gaseous Diffusion

Gaseous diffusion is a method used to separate gases based on their molecule weight. The lighter molecules (in this case, hydrogen) will diffuse faster than the heavier molecules (in this case, neon). Therefore, if the gas mixture is allowed to diffuse over time, the concentration of the lighter gas will be higher in areas further from the source of the gas.

Compare the physical and chemical properties of \(\mathrm{H}_{2} \mathrm{O}\) and \(\mathrm{H}_{2} \mathrm{~S}\).

Lubricants used in watches usually consist of longchain hydrocarbons. Oxidation by air forms solid polymers that eventually destroy the effectiveness of the lubricants. It is believed that one of the initial steps in the oxidation is removal of a hydrogen atom (hydrogen abstraction). By replacing the hydrogen atoms at reactive sites with deuterium atoms, it is possible to substantially slow the overall oxidation rate. Why? (Hint: Consider the kinetic isotope effect.)

Write a balanced equation for each of the following reactions: (a) Heating phosphorous acid yields phosphoric acid and phosphine \(\left(\mathrm{PH}_{3}\right) .\) (b) Lithium carbide reacts with hydrochloric acid to give lithium chloride and methane. (c) Bubbling HI gas through an aqueous solution of \(\mathrm{HNO}_{2}\) yields molecular iodine and nitric oxide. (d) Hydrogen sulfide is oxidized by chlorine to give \(\mathrm{HCl}\) and \(\mathrm{SCl}_{2}\).

Hydrogen peroxide can be prepared by treating barium peroxide with sulfuric acid. Write a balanced equation for this reaction.
