Final answer:
Oxidation does not usually change the shape and/or function of a substance.
Step-by-step explanation:
The statement is false. The process of oxidation does not usually change the shape and/or function of a substance. Oxidation is the loss of one or more electrons in a chemical reaction, and the substance that loses electrons is said to be oxidized. This process often occurs in conjunction with reduction, which is the gain of electrons. Oxidation and reduction reactions must occur together as a pair.
