Ad libitum [116K]

Answer:

Los elementos de la tabla periódica se distribuyen sobre la base de similitudes.

Explicación:

Los diferentes tipos de elementos se distribuyen en 8 grupos de tabla periódica en función de sus propiedades. Los elementos que tienen propiedades similares se colocan en el mismo grupo. Por ejemplo, el primer grupo de la tabla periódica son los metales alcalinos. Todos los metales alcalinos tienen algunas propiedades similares, es decir, un electrón en su capa más externa, alta reactividad y forma metálica, mientras que, por otro lado, los ocho elementos del grupo son gases nobles que tienen una capa más externa completa y no tienen reactividad.

A mixture of benzoic acid and naphthalene was dissolved in tert-butyl methyl ether and the resulting solution was extracted with
Llana [10]

Answer:

C₆H₅COOH Benzoic Acid

Explanation:

Here we are using the extraction method to separate  benzoic acid from naphtalene in the  ether solution  by reacting it with the base sodium bicarbonate to produce the salt sodium benzoate  ( naphtalene remains in the organic layer )  .

The sodium benzoate  is completely soluble in the aqueous layer being a salt, and  reacts with hydrochloric acid ( again an acid base reaction ) which precipitates the benzoic acid  since the it is insoluble in water hence  separating it.
