Question

Which of the following statements accurately describes silicon carbide?

A) Food Electronics
B) Australia 20 5
C) Korea 8 4
D) None of the above

Answer 1

Silicon carbide has a high melting point and is used as an abrasive due to its hardness. It's also worth noting that pure silicon is a semiconductor and critical for electronic devices.

Step-by-step explanation:

Silicon carbide is a compound that, based on its properties, accurately falls under the description in your question. This compound has a high melting point of 2986°C and is known for being exceptionally hard. Due to its strong covalent bonds, it is used commercially for abrasive applications, such as in sandpaper and grinding wheels. While it does not conduct electricity very well, it's important to note that pure silicon has semiconductor properties, which make it essential in the production of microchips and other electronic devices.
