1º BACHILLERATO/QUÍMICA/TERMOQUÍMICA/ENTALPÍAS DE REACCIÓN Hervir agua Queremos calentar agua y convertir en vapor a 100 ºC, #masa Kg de agua que están a 0ºC: hallar los Kg de #comp que necesitaremos quemar suponiendo que se aprovecha el #rend % del calor desprendido en la combustión.

DATOS: Calor esp (agua) = 1 Kcal/Kg K; Calor vapor (agua) = 539.5 Kcal/kg; calor de combustión (#comp) = #ccomb KJ/mol

(1 J = 0.24 cal)
