Butane (C4H10(g), deltaHf =-125.6 kJ/mol reacts with oxygen to produce carbon dioxide (CO2 delta Hf =-393.5 kJ/mol)
Answers: 2
, Hf = –125.6 kJ/mol) reacts with oxygen to produce carbon dioxide (
, Hf = –393.5 kJ/mol ) and water 
, Hf = –241.82 kJ/mol) according to the equation below. What is the enthalpy of combustion (per mole) of 
?
![\Delta H=\sum [n\times \Delta H_f(product)]-\sum [n\times \Delta H_f(reactant)]](/tpl/images/0980/3076/76c37.png)
![\Delta H=[(n_{CO_2}\times \Delta H_{CO_2})+(n_{H_2O}\times \Delta H_{H_2O})]-[(n_{O_2}\times \Delta H_{O_2})+(n_{C_4H_{10}}\times \Delta H_{C_4H_{10})]](/tpl/images/0980/3076/2e436.png)
(as heat of formation of substances in their standard state is zero![\Delta H=[(4\times -393.5)+(5\times -241.82)]-[(\frac{13}{2}\times 0)+(1\times -125.6)]](/tpl/images/0980/3076/29cd1.png)
