Dodecylbenzene (C12H25C6H5) with sodium hydroxide (NaOH)= no reaction? Fatty alcohol (C12-16) with sodium hydroxide = Fatty alcohol salt? Monoétanolamine (C2H7NO) with sodium hydroxide = reaction? Ammonia solution with sodium hydoxide = NH3 (gas) with water?
Precipitation reactions are those in which the reactants exchange ions to form an insoluble salt—one which does not dissolve in water. Reaction occurs when two ions combine to form an insoluble solid or precipitate. We predict whether such a compound can be formed by consulting solubility rules...
chemical reaction n (Chemistry) a process that involves changes in the structure and energy content of atoms, molecules, or ions but not their nuclei. Comparenuclear reaction Collins English Dictionary – Complete and Unabridged, 12th Edition 2014 © HarperCollins Publishers 1991, 1994, 1998, 2000...
Acid-base neutralization reaction is an important chemical reaction in chemistry. It occurs when an acid reacts with a base to form a salt and water. The principle behind this reaction is based on the transfer of hydrogen ions (H⁺) from the acid to the hydroxide ions (OH⁻) from the...
Understanding the Law of Conservation of Mass The law of conservation of mass states that mass is conserved in a chemical reaction; the total mass of the reactants equals the total mass of the products. This fundamental principle underpins the process of balancing chemical equations. ...
