Chemical shifts of fluorine in solutions of hydrogen fluoride, sodium fluoride, potassium fluoride, cesium fluoride, silver fluoride, silver bifluoride, ammonium bifluoride, and tetraethylammonium fluoride have been measured. Hydrogen fluoride was dissolved in water and in aqueous and anhydrous organic ...
Chemical formulae provide insight into the elements that constitute the molecules of a compound and also the ratio in which the atoms of these elements combine to form such molecules. For example, the chemical formula of water, which is H2O, suggests that two hydrogen atoms combine with one ...

Ethylene tends to cause hazardous reactions such as spontaneous polymerization and even explosion in contact with definite chemicals, namely fluorine, acetylene, hydrogen and oxides (IFA, 2015). Moreover, it can exhibit hazardous properties by formation of explosive mixtures in contact with air. In ...
