iron(III) oxide
is only part of the redox chemistry. Once you put up a bridge or a skyscraper, which is inevitably steel-based structure, it will begin to corrode.
Answer:
False
Explanation:
The temperature at which a solid melts, known as its melting point is highly characteristic of a compound and element.
The melting point of pure substances, compounds and elements is definite and not varied.
- Melting point is an intensive property of matter.
- It does not depend on the amount of matter present.
- It is an innate or intrinsic property of every matter.
- For example, no matter the volume or mass of water, it will always boil at 100°C, all things being equal.
Therefore, melting point of most solids is characteristic of compounds and elements.
