Smelting copper involves the extraction of copper from its ore through heating and the addition of reducing agents, typically carbon. This process results in the transformation of the ore into metallic copper, as well as the release of gases and the formation of slag. The formation of new substances and the irreversible nature of these changes are key indicators that smelting is a chemical change.

Which of these processes indicates that smelting copper is a chemical change?
When copper ore is heated in a furnace, it undergoes a chemical reaction that separates the copper from the other elements in the ore. This process of extracting the pure copper from its ore through smelting is a chemical change because the chemical composition of the copper is altered.

What is the significance of the oxidized form in the chemical reaction?
The oxidized form in a chemical reaction is important because it indicates the loss of electrons from a substance, leading to a change in its chemical properties. This process is crucial for understanding how substances interact and transform in reactions.
