Calor carbonato cálcico
Una muestra de carbonato cálcico se descompone térmicamente dando #mox g de óxido de calcio (s) y dióxido decarbono (g). Calcular el calor absorbido o desprendido en el proceso. (Datos: ΔH0f CaO (s) = -633 KJ/mol; ΔH0f CO2 (g) = -393.5 KJ/mol; ΔH0f CaCO3 (s) = -1207.6 KJ/mol; A(Ca)=40; A(C)=12; A(O)=16)]]>
