La combustin completa de isooctano a 25C puede representarse por: C8H18 (l) + 25/2 O2 (g) --> 8CO2 (g) + 9H2O (l) a) Calcule ngas

La combustin completa de isooctano a 25C puede representarse por:
C8H18 (l) + 25/2 O2 (g) --> 8CO2 (g) + 9H2O (l)
a) Calcule ngas cuando se queman completamente 0,692 g de isooctano (114,23 g/mol).
b) Calcular (n R Ti) cuando 0,692 g de isooctano se queman por completo a 25,0C.
c) Use la ecuacin para calcular H cuando 0,692 g de isooctano se queman por completo a 25 C.
d) Calcular el calor de combustin en kJ/mol a 25C. El calor de combustin de una sustancia es simplemente la relacin entre el cambio de entalpa cuando se quem esa sustancia y el nmero de moles de la sustancia que se quem.
