Answer 2

Oxidation is the loss of electrons during a reaction by a molecule, atom or ion. Oxidation occurs when the oxidation state of a molecule, atom or ion is increased. The opposite process is called reduction, which occurs when there is a gain of electrons or the oxidation state of an atom, molecule, or ion decreases.ㅤㅤㅤㅤㅤㅤㅤ

$= = > \huge\mathtt\red{2 \times \frac{22}{7} \times 19}$

$= = > \huge\mathtt\red{ \frac{44 \times 19}{7} }$

$= = > \huge\mathtt\red{ \frac{836}{7} }$

$= = > \huge\mathtt\green{119.42 |approx| }$
