Question
Which of the following fertilizer is manufactured by using carbon dioxide?
- Urea
- Ammonium Nitrate
- Fluorapatite
- All of these
Hint:
The chemical formula of urea is NH2CONH2.
The correct answer is: Urea
Ammonia can be combined with carbon dioxide from the first step to manufacture urea fertiliser. It is worth noting that the production of urea does not produce carbon dioxide as a by-product, but consumes carbon dioxide which is later released when the fertiliser is applied to crops, contributing to the fertiliser carbon footprint.
