What is the boiling point of pentane? If acetone is added to water can acetone be still detected? If yes, explain why? How do impurities in a substance lower the melting point? Explain your answer. What is the boiling point of actinium?
What is a polar solvent? Explain. Covalent BondWhen two atoms share electrons, a chemical bond is created known as a covalent bond. Similar electronegativity among the atoms causes them to share electrons in order to produce a stable electron configuration and create a molecule....
Crystallization can be defined as the chemical or physical process in which a solid crystal is obtained from a hot solvent by allowing the solvent to cool itself. To obtain a crystal, the solute dissolved in the solvent, the solvent itself and the time allowed plays a major role...
If desired, the fluidity of the catalyst layer may be increased by commingling it with a nonreactive hydrogen solvent, such as pentane, and after thorough mixing, the solution is treated with a suitable alkaline reagent to neutralize any remaining free acid present. The treated mixture is directe...
chemistry the termaliphaticsimply means that we are dealing with a compound in which all of the carbon-carbon bonds are single bonds, no double or triple bonds are allowed. For example, the compound pentane would be considered aliphatic. Notice how there are only single bonds connecting the ...
lsopentane is generally marketed in a compressed liquefied form. Isopentane is used as a solvent, is a building-block chemical used in reactions to form other industrial substances, and has been used in the manufacture of chlorinated derivatives and the production of amyl-naphthalene and isoprene....
2, relatively low-level ion pair reagents, when the requirements are not high, cheaper than heptane, sodium pentane sulfonate. 3, as a raw material, modification of materials. 4, capillary electrophoresis analysis, additives, generally used as a molar solution 5,...
