Answer 1

Answer:

Explanation:

Rusting of iron refers to the formation of rust, a mixture of iron oxides, on the surface of iron objects or structures. This rust is formed from a redox reaction between oxygen and iron in an environment containing water (such as air containing high levels of moisture)

Answer 2

In the case of everyday copper utensils, copper is most likely to form a brown or black tarnish in the presence of oxygen, moisture, human touch, dust, and certain chemicals. This tarnishing can further develop, leading to corrosion (or patina), which is usually green.
