The elements that undergoes oxidation and reduction in the given three reactions. Concept introduction: The loss of the electrons by the substance is known as oxidation and the gain of the electrons by the substance is known as reduction. The substance which donates the electrons is said to be oxidized whereas the substance which accepts the electrons is said to be reduced. Oxidation number represents the oxidation state of the ions. An increase in oxidation number occurs by the loss of electrons while the oxidation number decreases by the gaining of electrons.

A complete tensile test was performed on a magnesium
specimen of 12 mm diameter and 30 mm length, until breaking.
The specimen is assumed to maintain a constant volume.
Calculate the approximate value of the actual stress at breaking.
TABLE. The tensile force F and the length of the specimen are
represented for each L until breaking.
