Answer : The correct option is, (3) an Arrhenius acid

Explanation :

According to the Arrhenius concept, an acid is a substance which ionizes in the water to give hydronium ion $(H_3O^+)$ or hydrogen ion $(H^+)$ and a base is a substance which ionizes in the water to give hydroxide ion $(OH^-)$ .

When one compound dissolves in water, then only positive ion produced in the solution is $(H_3O^+)$ . This compound is classified as an Arrhenius acid.

Hence, the correct option is, (3) an Arrhenius acid

In at least 4 complete sentences, describe the similarities and differences between Avogadro's Law and Charles' Law.

viktelen [127]

answer

Avogadro's law states that, at constant temperature and pressure, the volume of a gas is directly proportional to the number of moles present. In other words, equal volumes of gases at the same pressure and temperature contain the same number of molecules - this is true regardless of their physical properties or chemical nature.

This number of molecules is

6.022

⋅

and is known as Avogadro's number,

Matematically, Avogadro's law can be written like this

, or, better yet,

Avogadro's law, as well as Boyle's law and Charles' law, are special cases of the ideal gas law,

. If temperature and pressure are kept constant, and knowing that

is of course constant, then

→

, which represents Avogadro's law.

The ideal gas law can also be written to incorporate

, since the number of moles are actually the number of molecules divided by Avogadro's number

⋅

, where

represents the number of molecules.
