Question
Complete the following analogy:
Calcium carbide: ripening agent: Carbon monoxide:
- Medicinal tablets
- War gas
- Manufacture borax
- Preparation of baking powder
Hint:
Carbon monoxide is a highly toxic gas.
The correct answer is: War gas
The correct option is c)War gas.
Calcium carbide: ripening agent: Carbon monoxide: War gas.
Calcium carbide is also used as a ripening agent in fruits such as mangoes, bananas, jackfruit, and lychees. Packets of calcium carbide powder are stored in fruit containers and when in contact with moisture, acetylene acts as a ripening agent. A gas is produced.
Carbon monoxide is a a very toxic gas. It binds with the hemoglobin in the blood to make carboxyhemoglobin. It reduces the oxygen reducing capacity of hemoglobin.
