The answer is that, from the answer choices, placing zinc and copper in an electrolyte is most likely involved with the study of electrochemistry.

Electrochemistry is the use study of the chemical reactions in relation to electric energy. It comprises the use of electric energy to produce chemical changes and the use of chemical reactions to produce electric energy.

The chemical reactions that produce or use electric energy are carried out in electrolytic cells.

Electrolytic cells consist of a pair of electrodes submerged in an electrolytic solution.


Zinc and copper are good pieces of conductors that work as electrodes in the electrolytic solution. Then, this is the correct answer..

Two students made the Lewis dot diagrams of NH3. The diagrams are as shown.
Neko [114]

Answer :  The correct option is, Only Student B

Explanation :

Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.

In the Lewis-dot structure the valance electrons are shown by 'dot'.

The given molecule is, NH_3

As we know that nitrogen has '5' valence electrons and hydrogen has '1' valence electron.

Therefore, the total number of valence electrons in NH_3 = 5 + 3(1) = 8

According to Lewis-dot structure, there are 6 number of bonding electrons and 2 number of non-bonding electrons.

The Lewis dot structure of student A is wrong because there is a coordinate bond present between the nitrogen and hydrogen is not covalent.

The correct Lewis-dot structure of NH_3 is shown by the student B.
