Hydrogen and chlorine, while not noble gases, play crucial roles in chemical reactions that produce compounds useful in various applications. Hydrogen is essential for fuel cells, energy storage, and as a reducing agent in chemical processes, while chlorine is widely used for disinfection, water treatment, and in the production of plastics and other chemicals. Noble gases like helium, on the other hand, are inert and are used in applications like cryogenics, balloons, and lighting due to their non-reactive nature. Together, these elements contribute to a wide range of industrial and technological advancements.
What else can I help you with?
Does helium burn or rust?
No. Helium is a noble gas and has a full compliment of electrons in the first 'orbit' of its atoms. This makes it very, very stable and inert. Therefore helium forms no compounds with any other element. As burning in air by definition is the reaction between the substance and oxygen in the air to form an oxide (e.g. charcoal (carbon) burns in air on your barbecue to form carbon dioxide), as helium will not react with oxygen it will not burn. Helium is also lighter than air. Therefore, helium is sometimes used to fill airships to provide a lift. Airships were once filled with hydrogen as hydrogen is also lighter than air, but several disasters happened where the airship caught fire killing the occupants inside- as hydrogen reacts well with the oxygen in the air (even explosively) form hydrogen oxide (water vapour). As helium is so inert,. it is very useful AND safe for such a use nowadays.
What quality of helium makes it useful?
Helium is lighter than air (which means it can be used to make stuff float, like balloons) and a noble gas (which means that it won't react with other elements). Both of these qualities make helium very useful.
Why pcl5 acts as chlorinating agent?
Phosphorus pentachloride (PCl5) acts as a chlorinating agent due to its ability to release chlorine atoms upon reaction with other substances. In the presence of moisture or certain organic compounds, PCl5 can dissociate to form phosphorus oxychloride (POCl3) and chlorine gas (Cl2), facilitating the introduction of chlorine into various organic molecules. This property makes it useful in organic synthesis and chlorination reactions, where the substitution of hydrogen atoms with chlorine enhances the reactivity or stability of the resulting compounds.
What is a greenish yellow gas used as bleach and water disinfectant?
This is Chlorine (Cl2) present in neutral bleach (NaCl2OH)
Why is helium useful?
Helium is useful because it is a non-reactive gas that is lighter than air, making it ideal for filling balloons, airships, and blimps. It is also used in cryogenics for cooling purposes, in medical applications such as MRI machines, and in the aerospace industry for purging fuel tanks.
What properties make helium useful?
While it is not a "Noble Gas" it is much lighter than air. It is not lighter than Hydrogen, but it does not ignite as easily.
What are The advantages and disadvantages of helium in airships?
First of all, there isn't much choice. To get the airship to lift, one has to use a gas that's lighter than air. Only two do that well enough to be useful, hydrogen and helium. Hydrogen is lighter and cheaper, but horribly flammable. Helium is more expensive, provide less lift, but is entirely non flammable.
How useful is helium?
How Helium is used: It is used to blow up balloons.
Does chlorine support combustion?
Chlorine gas supports the vigorous combustion of many elements to form their chlorides. For example, Sulphur and Phosphorus burn in the gas.
What is a poisonous but useful element?
chlorine
Characteristics of helium?
Helium is a gas which is very light. It is the second lightest element in the universe. Helium was discovered in 1986. William Ramsay confirmed it was helium. Helium remains as gas up to 25c (77f). Helium has no taste or no color. Helium doesn't combine with other elements. It is a by product of the reaction of hydrogen in the sun.
What moons are most likely to be visited by humans due to valuable resources?
At this point the only valuable resources would be those useful in refueling rockets for a return voyage, usually oxygen, nitrogen, helium, hydrogen etc.
How is chlorine compound useful?
like in pools, it keeps em clean ;]
What are the things you can do with chlorine that make it useful?
You can use it as a bleach and to sterilize objects.
What is the most useful compound of hydrogen?
water
