Enthalpy of combustion of carbon to CO(2...

Enthalpy of combustion of carbon to `CO_(2)` is `-393.5 kJ mol^(-1).` Calculate the heat released upon formation of 35.2 g of `CO_(2)` from carbon and dioxygen gas.

Text Solution

Verified by Experts

Moles of `CO_(2)=(35.2)/(44)=0.8`
Heat of formation of `CO_(2)=(-393.5)(0.8)=-315 kJ`
