Answer:The Lewis acid the in the given reaction is Cr^{3+} ion.

Explanation:

According Lewis Theory of  acid base concept:

  • Acids are those who accepts pair of electron pair
  • Bases are those who donates pair of electron pair.

Cr^{3+}(aq)+6H_2O(aq)\rightleftharpoons Cr(H2O)_{6}^{3+}(aq)

In the above reaction chromium (III) ion is acting as a Lewis acid and water is acting as Lewis base. Chromium ion easily accepts the electron pair that is lone pair of oxygen atom present in water molecule.

In the reaction,
Cr3+(aq) + 6H2O -------> [Cr(H2O)6]3+(aq)
Cr3+ IS THE LEWIS ACID H2O is the Lewis base.
A Lewis acid is a compound or chemical that accepts a lone pair of electrons. In the above equation, Cr3+ is accepting the lone pair of electrons.

Which of the following statement(s) are true about the atoms of any element?
Sunny_sXe [5.5K]

Answer: The answers are:

The number of protons in an atom of an element is unique to each element.

A proton in an atom of one element is identical to a proton in an atom of another element.

Explanation: The number of protons in an atom of an element is unique to each element. The number of protons in an atom of an element is the atomic number of that element. Atomic number determines the chemical properties and reactivity of the atom.

All atoms are made up of three particles: protons, electrons and neutrons. These particles are identical in all the elements, what distinguishes one element from another is the number of each of these particles it contains. Therefore, a proton in an atom of one element is identical to a proton in an atom of another element likewise the electrons and neutrons.
