Hi this is my first time using this, hopefully it will be helpful. I am havingf a hard time starting this problem.

Balance the combustion reaction of chrysene (C18H12) at 298K.

What is the value of ng for the combustion reaction?

    ng =_____ mol

What is Hcomb of chrysene if Ecomb = -8942.6 kJ/mol?

    Hcomb =______ kJ/mol

What is the heat of formation of chrysene?

    Hf = ______ kJ/mol


I was able to balance the equation but I am not sure what exactly to do next. Can anyone get me pointed in the right direction for the following three questions?


1 C18H12(s) + 21 O2(g)  18 CO2(g) + 6correct check mark H2O(l)

ng = -3

delta H comb = -8950

delta H formation = 151.84
