-xA0-The balanced chemical reaction for the combustion of C to CO2 is given below-C-s-O2-g-x2192-CO2-g-xA0-xA0-xA0-x394-H-x2212-393-5kJ-molThe formation of-xA0-44g-1 mol- of CO2 releases 393-5 kJ of heat-The formation of 35-2 g of CO2 releases-xA0- 393-5-xD7-35-244-314-8kJ of heat-

Enthalpy of combustion of carbon to CO2 is -393.5 kJ mol−1. Calculate the heat released upon formation of 35.2g of CO2 from carbon and dioxygen gas.

The balanced chemical reaction for the combustion of C to CO2 is given below:C(s)+O2(g)→CO2(g); ΔH=−393.5kJ/molThe formation of 44g(1 mol) of CO2 releases 393.5 kJ of heat.The formation of 35.2 g of CO2 releases 393.5×35.244=314.8kJ of heat.

Enthalpy of combustion of carbon to $C O_{2}$ is -393.5 kJ $m o l^{- 1}$ . Calculate the heat released upon formation of 35.2g of $C O_{2}$ from carbon and dioxygen gas.
