Answer:
B. Although both involve combining with oxygen, combustion is more rapid.
Step-by-step explanation:
Both rusting and combustion involves are combination in which a substance reacts with oxygen.
- The difference between both processes is that burning is a rapid process. Oxygen combines with a fuel in a very fast rate.
- Rusting is a slow process and it takes time.
- Water vapor is often needed for this reaction to take place.
- The rate at which combustion occurs is more rapid compared to slow, rusting process.
