Calcium Carbide
Calcium Carbonate
Calcium Cyanide
Calcium Sulphate
Answer is Wrong!
Answer is Right!
The correct answer is D. Calcium Sulphate.
Calcium sulphate is a common fertilizer because it is a source of calcium and sulphur, both of which are essential for plant growth. It is also relatively inexpensive and easy to apply.
Calcium carbonate is another common fertilizer, but it is not as effective as calcium sulphate because it is
not as easily absorbed by plants. Calcium carbide is a dangerous substance that should not be used as a fertilizer. Calcium cyanide is a deadly poison that should never be used as a fertilizer.Here is a more detailed explanation
of each option:- Calcium carbide is a chemical compound with the formula CaC2. It is a white, solid that is used to produce acetylene gas. Calcium carbide is not a fertilizer and should not be used as such.
- Calcium carbonate is a chemical compound with the formula CaCO3. It is a white, solid that is found in limestone, chalk, and marble. Calcium carbonate is a common fertilizer because it is a source of calcium, which is an essential nutrient for plants. However, calcium carbonate is not as effective as calcium sulphate because it is not as easily absorbed by plants.
- Calcium cyanide is a chemical compound with the formula Ca(CN)2. It is a white, solid that is used to produce cyanide gas. Calcium cyanide is a deadly poison and should never be used as a fertilizer.
- Calcium sulphate is a chemical compound with the formula CaSO4. It is a white, solid that is found in gypsum and anhydrite. Calcium sulphate is a common fertilizer because it is a source of calcium and sulphur, both of which are essential for plant growth. It is also relatively inexpensive and easy to apply.
