Answer:
The correct answer is E. All of these are true.
A. Patina is the layer of tarnish that gives silver a richer appearance. This is true. Patina is a thin layer of corrosion that forms on the surface of metals, such as silver, copper, and bronze. It can be a variety of colors, including green, blue, and brown. Patina is often considered to be desirable, as it gives the metal a more aged and rustic appearance.
B. The oxidation of most metals by oxygen is spontaneous. This is true. The oxidation of metals is a chemical reaction in which the metal reacts with oxygen to form an oxide. This reaction is spontaneous, which means that it will happen on its own without any input of energy.
C. Most metals will develop a thin oxide coating, which protects their internal atoms from oxidation. This is true. The oxide coating that forms on the surface of metals is a barrier that prevents the metal from reacting with oxygen. This barrier is very thin, but it is very effective at preventing oxidation.
D. A car exposed to the elements will rust faster in the Midwest than in Arizona. This is true. The Midwest is a region of the United States that is known for its humid climate. The humidity in the air causes the metal to rust more quickly. Arizona, on the other hand, is a desert state with a very dry climate. The dryness in the air prevents the metal from rusting as quickly.
Therefore, all of the statements about corrosion are true.
