An old iron battery was discarded in this meadow. The iron in the battery is undergoing a change as it rusts. The rusting is changing the battery's color from black to orange. A) physical B) chemical C) environmental D) none of these changes are occurring

chemical

Explanation:

A chemical change is irreversible and leads to the formation of new products.

Rusting occurs as a result of an irreversible chemical reaction between iron, oxygen and moisture. Rusting is the oxidation of iron when exposed to oxygen and moisture.

The rusting of iron is an electrochemical process in which water serves as the electrolyte and iron serves as the anode. The rusting of iron leads to the formation of hydrated iron III oxide (rust) usually seen an brown flakes that surround a rusted iron material.
