Zinc is costlier than tin
Zinc is more reactive than tin
Zinc is less reactive than tin
Answer is Right!
Answer is Wrong!
The correct answer is: D. Zinc is less reactive than tin.
Tin is a more noble metal than zinc, which means that it is less reactive and more stable. This makes it a better choice for coating food cans, as it will not react with the food or the environment and cause it to spoil. Zinc, on the other hand, is more reactive and can corrode more easily. This could lead to the food in the can becoming contaminated or spoiled.
Here is a brief explanation of each option:
- A. Zinc is costlier than tin. This is not the reason why food cans are coated with tin and not with zinc. Tin is actually more expensive than zinc. However, tin is a better choice for coating food cans because it is less reactive.
- B. Zinc has a higher melting point than tin. This is not the reason why food cans are coated with tin and not with zinc. The melting point of a metal does not affect its reactivity.
- C. Zinc is more reactive than tin. This is not the reason why food cans are coated with tin and not with zinc. Zinc is more reactive than tin, which means that it is more likely to corrode. This could lead to the food in the can becoming contaminated or spoiled.
- D. Zinc is less reactive than tin. This is the reason why food cans are coated with tin and not with zinc. Tin is a more noble metal than zinc, which means that it is less reactive and more stable. This makes it a better choice for coating food cans, as it will not react with the food or the environment and cause it to spoil.
