Question

Carbon dioxide is also released into the atmosphere when calcium carbonate rock (limestone) is heated to produce the quicklime, i.e., calcium oxide, used in the manufacture of cement: CaCO3(s) ? CaO(s) + CO2(g) Calculate the mass, in metric tons, of CO2 released per metric ton of limestone used in this process. What is the mass of carbon that the air gains for each gram of carbon dioxide that enters the atmosphere? Note that at least as much carbon dioxide is released from combustion of the fossil fuel needed to heat the limestone as is released from the limestone itself.
