Answer 1

Oxidation is the process of adding oxygen or removing hydrogen from a substance.

Example: Adding oxygen

$\mathrm{C}+{\mathrm{O}}_2\to {\mathrm{CO}}_2$

$\left(\mathrm{Carbon}\right)\left(\mathrm{Oxygen}\right)(\mathrm{Carbon}\mathrm{dioxide}\mathrm{gas})$

Example: Removing hydrogen

${\mathrm{H}}_2\mathrm{S}\to {\mathrm{H}}_2+\mathrm{S}$

$(\mathrm{Dihydrogen}\mathrm{sulfide})\left(\mathrm{Hydrogen}\right)\left(\mathrm{Sulfur}\right)$
