Hey, I need some help with the following question:(adsbygoogle = window.adsbygoogle || []).push({});

A sample of 0.1964g of Quinone (C6 H4 02, Relative Molar Mass = 108.1) was burned in a bomb calorimeter that heas a heat capacity of 1.56 kJ/M. The temperature in the caolorimeter rose from 19.3 to 22.5 degrees celcius.

(a) write a balanced equation for the complete combustion of quinone in oxygen to form water and CO2.

Ok I'm pretty sure this is right:

[tex]C_6 H_4 O_2 + 6O_2 \to 2H_2 O + 6CO_2 [/tex]

(b) Calculate the heat of combustion of quinone in kJ/g and kJ/mol.

Not exactly sure how to apprach this bit..

Q = CMT

where T is the difference in temp. M is the mass and C is the specific heat capcity, but I'm unsure how to apply this to the question.

thanks in advance.
