To determine the quantity of limestone (calcium carbonate, CaCO₃) needed to produce 56 kg of calcium oxide (CaO), we use the decomposition reaction:
[ \text{CaCO}_3 \rightarrow \text{CaO} + \text{CO}_2 ]
The molar mass of CaO is approximately 56 g/mol, and the molar mass of CaCO₃ is about 100 g/mol. Therefore, from the stoichiometry of the reaction, 100 g of CaCO₃ produces 56 g of CaO. To find the amount of limestone required for 56 kg of CaO, we calculate:
[ \text{Required CaCO}_3 = \frac{100 , \text{g}}{56 , \text{g}} \times 56000 , \text{g} \approx 100000 , \text{g} \text{ or } 100 , \text{kg} ]
Thus, 100 kg of limestone will yield 56 kg of CaO.

Should limestone be used for aggregate?
Yes, limestone is commonly used as an aggregate in construction due to its durability and availability. It is an excellent choice for use in concrete and asphalt production, providing strength and stability to the final product.
Why is limestone called a organic rock?
Limestone is not generally referred to as an organic rock. It is primarily composed of calcium carbonate, which is a mineral. However, in some cases, limestone can contain remnants of organic matter such as shells, coral, or other marine organisms, which can give it a slightly organic origin. This is why some people may refer to limestone as an organic rock.
Why avoid young peat bed roots and limestone?
Young peat bed roots are not well-established and can be easily damaged, impacting the growth and health of the plant. Limestone can alter the pH of the soil, making it too alkaline for some plants to thrive. Avoiding these can help ensure the health and growth of your plants.
