Explain oxygen forming carbon dioxide is exothermic

Reference no: EM13277745

The combustion of carbon with excess oxygen forming carbon dioxide is exothermic. C(s) + O2(g) => CO2(g) ?Hrxn = -393 kJ If 5,284kJ of heat is needed from the combustion, how much carbon (g) must be consumed? Enter your answer with three significant figures and do not include units.
