what is the second mentioned use ?
It is the process of removing snow, ice or frost from a surface.
De-icing
De-icing is the process of removing snow, ice or frost from a surface.
why alkali metals have low melting and boiling points It is because metal atoms are held together by the electromagnetic attraction from the positive ions to the delocalised electrons. what are they ? They are all shiny, soft, highly reactive metals at standard temperature and pressure and readily lose their outermost electron to form cations with charge +1. give some examples of them ? Lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr). what is the pricing of the first mentioned metal ? After the 2007 financial crisis, major suppliers, such as Sociedad Química y Minera (SQM), dropped lithium carbonate pricing by 20% and it rose in 2012. is it used for air purification ? Yes, lithium hydroxide and lithium peroxide are the salts most used in it. the above company who dropped their prices where is it located ? Its headquartered in Santiago. what other products it offers ? Plant nutrients, iodine and industrial chemicals is the second mentioned metal above is safe ? No, it forms flammable hydrogen and caustic sodium hydroxide on contact with water; ingestion and contact with moisture on skin, eyes or mucous membranes can cause severe burns. what are it's uses ? Anti-icing and de-icing and as a preservative

De-icing [SEP] Introduction
De-icing is the process of removing snow, ice or frost from a surface. Anti-icing is understood to be the application of chemicals that not only de-ice but also remain on a surface and continue to delay the reformation of ice for a certain period of time, or prevent adhesion of ice to make mechanical removal easier.
