Expressing resonance when drawing Lewis structures may be done either by drawing each of the possible resonance forms and placing double-headed arrows between them or by using dashed lines to represent the partial bonds (although the latter is a good representation of the resonance hybrid which is not, formally speaking, a Lewis structure).
Sodium amide, commonly called sodamide (systematic name sodium azanide), is the inorganic compound with the formula NaNH 2.It is a salt composed of the sodium cation and the azanide anion.
The most common Lewis bases are anions. The strength of Lewis basicity correlates with the pK a of the parent acid: acids with high pK a 's give good Lewis bases. As usual, a weaker acid has a stronger conjugate base. Examples of Lewis bases based on the general definition of electron pair donor include: simple anions, such as H − and F −
Latavion Lewis was arrested after a post office in Bonifay, Florida, received several reports of FedEx packages littering the roadside and wooded area during the busiest delivery season of the year.
The origins of the "uvas de la suerte" tradition are hard to trace. The idea might have begun with grape farmers in Alicante, Spain, to unload a surplus in the early 1900s, reported Atlas Obscura.

In chemistry, an acid–base reaction is a chemical reaction that occurs between an acid and a base.It can be used to determine pH via titration.Several theoretical frameworks provide alternative conceptions of the reaction mechanisms and their application in solving related problems; these are called the acid–base theories, for example, Brønsted–Lowry acid–base theory.
Corporate executives were taking a wait-and-see approach to President-elect Donald Trump's vow to impose heavy tariffs on imports when he takes office in January, but many have raised concerns ...
