Answer:

C.   Mg → Mg²⁺ + 2e−

Explanation:

The oxidation reduction reactions are called redox reaction. These reactions are take place by gaining or losing the electrons and oxidation state of elements are changed.

Oxidation:

Oxidation involve the removal of electrons and oxidation state of atom of an element is increased.

Reduction:

Reduction involve the gain of electron and oxidation number is decreased.

Consider the following reactions.

Mg + CuSO₄      →    MgSO₄  + Cu

Mg atom lose two electron and gets oxidized.

Mg → Mg²⁺ + 2e−

These two electrons are accepted by Cu and gets reduced.

CuSO₄       →      Cu²⁺ + SO₄²⁻

Cu²⁺ + 2e⁻   →  Cu

Give the clarification of heat and temperature on the basis of molecular motion?
sdas [7]

Explanation:

Heat is a form of thermal energy.

Heat is the sum of all the energy of the molecular motion in an object.

Temperature measures the average heat possessed by each molecule in a given substance.

 Molecules at a higher temperature possess more kinetic energy and they will move faster. This kinetic energy form is the heat variant of thermal energy.

Temperature is the measure of this heat energy of molecules.
