The reaction between lime (CaO(s)) and carbon dioxide (CO2(g)) forms the predominant mineral in limestone, CaCO3(s), (Delta Hrxn° = −177.1 kJ/mol, Delta Srxn° = −158.2 J/K∙mol). Lime is a key component in making concrete and is made from limestone. What is the minimum temperature required to shift the equilibrium toward lime (CaO(s)) from limestone (CaCO3(s))?

When Lime stone, CaCO3 Is heated above 600°C, it will produce CO2 Gas. CaCO3(s)-----> CaO(s) + CO2(g). 250 g of a clay that contains lime stone is heated, and 36.5 g of CO2 gas is collected. Assuming lime stone is the only component of the clay that can produce CO2, What is the percent of the clay is limestone?

Calcium oxide (Lime) is usually produced by heating and decomposing limestone (CaCO3), a cheap and abundant mineral, in a process: CaCO3 (s) CaO (s)+CO2 (g) a) Limestone at 25°C is fed to a continuous calcination reactor. The calcination is complete, and the products leave at 900 °C. Taking 1 metric ton (1000 kg) of limestone as a basis and elemental species [Ca(s), C(s), O2(g)] at 25°C as references for enthalpy calculations, prepare and fill in an inlet-outlet enthalpy table and...

When limestone (solid CaCO3) is heated, it decomposes into lime (solid CaO) and carbon dioxide gas. This is an extremely useful industrial process of great antiquity, because powdered lime mixed with water is the basis for mortar and concrete - the lime absorbs CO2 from the air and turns back into hard, durable limestone. Suppose some calcium carbonate is sealed into a limekiln of volume 250. L and heated to 870.0 °C. When the amount of CaCO3 has stopped changing,...
