Xenon hexafluoride was one of the first noble gas com-pounds synthesized. The solid reacts rapidly with the silicondioxide in glass or quartz containers to form liquid XeOF₄ and gaseous silicon tetrafluoride.

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.
