Stability of MX2-3 ions in the gas phase and when do ionic molecules have large ionization potentials.The present work aims at theoretical consideration of the geometrical and electronic structures of a homologous series of free MXmq--type alkali halides (M=Li, Na, K; X=F, Cl; m=1,2,...
But if salt needs to interact with liquid water, how does it do anything when temperatures are stubbornly below freezing, and water should already be in the form of ice? That’s where cars help clear their own ...

Dehydration synthesis is the process of removing water from two molecules to form a larger molecule. One molecule loses a hydrogen atom and the other molecule loses the hydroxide ion. These ions come together and form water. Hence, the new molecule loses water and the reaction is called ...
