Question

Choose the correct sequence of melting temperatures from highest to lowest:
Barium Carbonate,
Soda Ash,
Tin Oxide,
Silica,
Zinc Oxide.

• A. B, C, D, E, A
• B. A, B, C, D, E
• C. D, E, A, B, C
• D. E, C, D, A, B

Hint:

Begin with Barium Carbonate for the highest melting temperature and end with Zinc Oxide for the lowest.

Answer 1

The Correct Option is D

• Barium Carbonate has the highest melting temperature.
• Soda Ash follows next in melting temperature.
• Tin Oxide melts at a lower temperature than Soda Ash but higher than Silica.
• Silica melts at a lower temperature than Tin Oxide.
• Zinc Oxide has the lowest melting point.

The correct order is: Barium Carbonate > Soda Ash > Tin Oxide > Silica > Zinc Oxide.
