Charcoal is primarily carbon. what mass of co2 is produced if you burn enough carbon (in the form of charcoal) to produce 4.80 kj×102kj of heat? the balanced chemical equation is as follows:

When carbon is burned in air carbon iv oxide gas is formed.
C (s) + O2 (g) = CO2(g)  ΔH = - 393.5 kj/mol
The enthalpy change of the  reaction is -393.5 j/mol which means that when one mole of carbon is completely burnt in air then 393.5 j of energy is evolved.
Thus, 1 mole = -393.5 j , then for 480 kj 
            = 480 × 1/393.5
             = 1.2198 moles
          1 mole of carbon iv oxide is equal to 44 g 
thus, 1.2198 moles will be 1.2198 × 44 = 53.6712 g of CO2
