Praseodymium trifluoride is the fluoride of metal praseodymium, with the molecular formula PrF3·2H2O=233.93, green hexagonal crystal. The relative density is 6.14, the melting point is 1370°C (anhydrous salt), and the boiling point is 2327°C (anhydrous salt). Insoluble in water, it reacts...
The synthesis of LaB6 involves dissolvinglanthanum trioxideand borax in a suitable molten salt, followed by electrolysis with graphite anodes at high temperatures. This process deposits LaB6 on graphite or steel cathodes. Notably, its insolubility in water, hydrochloric acid, and its magenta solid f...
What are the physical properties of carbonate minerals? Recrystallization: Recrystallization is when a substance is dissolved so that it can be purified in a hot liquid. When the solvent cools down, the solution is saturated with the solute that crystalizes, or forms a solid again. Carbonate mine...
What is graphite? Graphite is a form of carbon. Graphite is silvery black in colour with a dull metallic sheen. Graphite is a very soft mineral. On the Mohs hardness scale, it lies between 1 and 2. Due to this softness and its tendency to flake, it is ideally suited for use as a ...
It can also occur at a molecular level, due to changes in the orientation of electrically polar molecules in response to an applied field, or through bending & stretching of the bonds between atoms within a molecule, very much like the material in a mechanical spring is bent or stretched. ...
Chemistry is the branch which deals with the detailed study of matter, its properties, how and why atoms/substanced combine or separate to form other substances. Understand all the basic concepts of Organic, Inorganic, and Physical Chemistry with detaile
This article presents a personal answer to the question “What is chemistry?”, set out in terms of six propositions. These cover “pureR
What is the molecular geometry around an atom in a molecule or ion which is surrounded by one lone pair of electrons and four single bonds? \\ A. T-shaped B. Linear C. Trigonal bipyramidal D. Trigonal planar E. See-saw What hybridization is associated...
