To find the mass of calcium oxide produced from a given mass of calcium carbonate, you can use stoichiometry based on the chemical reaction: ( \text{CaCO}_3 \rightarrow \text{CaO} + \text{CO}_2 ). The molar mass of calcium carbonate (CaCO₃) is approximately 100.09 g/mol, while that of calcium oxide (CaO) is about 56.08 g/mol. Therefore, for every 100.09 g of CaCO₃, 56.08 g of CaO is produced. You can calculate the mass of CaO produced by multiplying the mass of CaCO₃ by the ratio of their molar masses: ( \text{Mass of CaO} = \text{Mass of CaCO}_3 \times \frac{56.08}{100.09} ).
To calculate the mass of calcium oxide that can be produced from 4.7 kg of calcium carbonate, you need the molar masses of both calcium carbonate (CaCO₃) and calcium oxide (CaO). Additionally, you need to know the balanced chemical equation for the decomposition of calcium carbonate, which is: CaCO₃ → CaO + CO₂. Using this information, you can determine the moles of calcium carbonate and then use stoichiometry to find the corresponding mass of calcium oxide produced.
To calculate the mass of calcium oxide produced from the decomposition of calcium carbonate, you need the molar masses of calcium carbonate (CaCO₃) and calcium oxide (CaO). Additionally, you must know the amount (in grams or moles) of calcium carbonate you are starting with. Using stoichiometry from the balanced chemical equation, you can determine the mass of calcium oxide that can be produced.
The molar mass of calcium carbonate is 100.1 g/mol, and the molar mass of calcium oxide is 56.08 g/mol. Therefore, 12.25 grams of calcium carbonate would produce 6.86 grams of calcium oxide after decomposition.
I am not sure of the answer so can someone help me pls
the answer is 356.96 tonnes
To calculate the mass of calcium oxide that can be produced from 4.7 kg of calcium carbonate, you need the molar masses of both calcium carbonate (CaCO₃) and calcium oxide (CaO). Additionally, you need to know the balanced chemical equation for the decomposition of calcium carbonate, which is: CaCO₃ → CaO + CO₂. Using this information, you can determine the moles of calcium carbonate and then use stoichiometry to find the corresponding mass of calcium oxide produced.
The molar ratio between calcium carbonate and calcium oxide is 1:1. So, 25 moles of calcium carbonate will produce 25 moles of calcium oxide. The molar mass of calcium oxide is 56.08 g/mol, so the mass of calcium oxide produced will be 25 moles * 56.08 g/mol = 1402 g.

To calculate the mass of calcium oxide produced from 4.7 kg of calcium carbonate, you need to know the molar mass of calcium carbonate (CaCO3) and calcium oxide (CaO), as well as the stoichiometry of the reaction between these two compounds. This information will allow you to determine the theoretical yield of calcium oxide that can be obtained from the given mass of calcium carbonate.
The molar mass of calcium carbonate is 100.1 g/mol, and the molar mass of calcium oxide is 56.08 g/mol. Therefore, 12.25 grams of calcium carbonate would produce 6.86 grams of calcium oxide after decomposition.
When limestone is heated, it undergoes a chemical reaction that releases carbon dioxide gas, leaving behind calcium oxide. As a result, the mass of the limestone would be greater than the mass of the calcium oxide produced, due to the loss of carbon dioxide during the reaction.

2Ca + O2 --> 2CaO The molar mass of Calcium is 40g/mol. 36.5g/40g gives you 0.9125 moles of Calcium. The moles of calcium are equivalent to the moles of Calcium oxide. The answer is 0.9125 moles of calcium oxide. Correct me if I am wrong.
Calcium carbonate loses mass when heated because it decomposes into calcium oxide (quicklime) and carbon dioxide. This decomposition reaction releases carbon dioxide gas, causing the mass of the calcium carbonate to decrease.
