Limestone (CaCO3, 100.09 g/mol) is present in many sedimentary rocks. Suppose the limestone in a 5.000 g rock sample is dissolved in hydrochloric acid, and then 33.30 mL of 0.1500 M Na2C2O4 is added to precipitate the Ca2+ ions as CaC204 (128.10 g/mol). What is the mass percent limestone in the original rock sample? 10.00% 12.80% 17.35% 85.31% 66.67%

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))?

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...

Limestone (CaCO3) is used to remove acidic pollutants from gases inside smokestack flues. It is heated to form lime (CaO), which reacts with sulfur dioxide to form calcium sulfite. Assuming a 72.5% yield in the overall reaction, what mass of limestone is required to remove all the sulfur dioxide formed by the combustion of 3.0 × 104 kg of coal that is 0.16 mass % sulfur?
