Iron found in some minerals in basalt can react with oxygen and break down into iron oxide particles. This change is an example of

This change is an example of a chemical reaction, specifically oxidation. Here's the step-by-step explanation:

1. Iron (Fe) is a reactive metal that can combine with oxygen (O2) in the air. This process is known as oxidation.

2. When iron reacts with oxygen, it forms iron oxide (Fe2O3), commonly known as rust. This is a chemical change because new substances (iron oxide particles) are formed.

3. The reaction can be represented as follows: 4Fe + 3O2 → 2Fe2O3.

4. This process is common in basalt, a type of volcanic rock that contains iron-bearing minerals. When these minerals are exposed to air, the iron in them can react with oxygen and break down into iron oxide particles.

5. Therefore, the change of iron in basalt reacting with oxygen to form iron oxide particles is an example of a chemical reaction, specifically oxidation.
