The present invention provides a kind of solid of method activated by the fluorination of at least partly surface of solids oxygen, which includes exposure, in selected temperature and pressure and selected reaction time, at least partly solid of material surface to oxfluorinating atmosphere. Which...
Is fluorine a metal or nonmetal?Fluorine:Fluorine is a chemical element. On the Periodic Table of Elements, it is shown with the symbol 'F' and the atomic number 9. It has a melting point of minus 219.67 degrees Celsius and a boiling point of minus 188.11 degrees Celsius....
common salt,sodium chloride- a white crystalline solid consisting mainly of sodium chloride (NaCl) gas- a fluid in the gaseous state having neither independent shape nor volume and being able to expand indefinitely halogen- any of five related nonmetallic elements (fluorine or chlorine or bromine ...
PFA flasks are chosen as containers when the solution is corrosive and requires a long reaction or heated reflux. The main purpose (1) Reactor between liquid and solid or liquid; (2) Assemble the gas reaction generator (normal temperature, heating); (3) Distil...
What element is fluorine? What is a polar covalent molecule? What is the orbital notation for lithium? Why is fluorine special in terms of electronegativity? Why is the electronegativity of an element important? Which isotope of lithium has 3 neutrons?

F2 is a stronger oxidising agent than Cl2 View Solution H2O2 is a better oxidising agents than water. View Solution Which is the best oxidising agent? View Solution Statement-1 : Fluorine is a stronger oxidising agent than chlorine because Statement-2 : It has (i) low enthalpy of diss...
It is very non-reactive, partly because of the strength of carbon–fluorine bonds, and so it is often the choice of material used in containers and pipework for corrosive and reactive chemicals. Where used as a lubricant, PTFE has low friction, wear and energy consumption of machinery, here...
