Answer to Question #286916 in General Chemistry for eve

Question

using standard molar enthalpies of formation given, calculate the standard enthalpy of reaction for the combustion of propane (C3H8) into carbon dioxide and water.

C3H8(g)+5O2(g) = #CO2(g)+ 4H2O(g)

Substance= ΔH°f(kJ/mol)

C3H8(g)= -104.0

O2(g)= 0

CO2(g)= -393.5

H2O(g)= 241.8

Answer 1

Standard enthalpy =−2043.9kJ/mol
