The enthalpy associated with the formation of one mole quantities of calcium oxide, and carbon dioxide, from calcium carbonate is #+178*kJ#. How do we represent this reaction symbolically?

#CaCO_3(s) + DeltaH rarr CaO(s) + CO_2(g)uarr#

Explanation:

#"Moles of calcium carbonate"# #=# #(100*g)/(100.09*g*mol^-1)=1*mol.#

And thus for:

#CaCO_3(s) + DeltaH rarr CaO(s) + CO_2(g)uarr;# #DeltaH=178*kJ*mol^-1" of reaction as written"#

Given that it is endothermic reaction, we quote #DeltaH_"rxn"=+178*kJ*mol^-1#.

I can think of one industry where the reaction is utilized on a monumental scale. Can you identify it?
