Do free electrons appear anywhere in the balanced equation for a redox reaction?
Andru [333]

Yes, free electrons appear in balanced redox reaction equations. However, this is only true for half-reactions. This is because redox reactions primarily involve the transfer of electrons, which are better visualized if explicitly shown in the balanced reactions. In reduction reactions, electrons are placed on the left side of the equation. Oxidation reactions show electrons on the right side of the equation.


Explanation:

A half reaction is either the chemical reaction or reduction reaction part of an oxidoreduction reaction. A half reaction is obtained by considering the amendment in chemical reaction states of individual substances concerned within the oxidoreduction reaction. Half-reactions are usually used as a way of leveling oxidoreduction reactions.The half-reaction on the anode, wherever chemical reaction happens, is Zn(s) = Zn2+ (aq) + (2e-).

The metal loses 2 electrons to create Zn2+. The half-reaction on the cathode wherever reduction happens is Cu2+ (aq) + 2e- = Cu(s).

Here, the copper ions gain electrons and become solid copper.

Crystals a. grow inward from a seed. b. have an orderly internal arrangement of atoms organized in a lattice pattern. c. display
Andreyy89

Answer:

Option (B)

Explanation:

Crystals are usually defined as those substances that are comprised of atoms, ions, and molecules, and they are oriented in a very well-developed and ordered microscopic structure. These crystals are interlinked to one another by strong chemical bonds, namely the metallic, covalent, ionic and Vander Waals bond. In nature, these crystals form when any liquid undergoes cooling and solidifies.

The study of crystals is commonly known as crystallography and is directly associated with the minerals.

Thus, the correct answer is option (B).
