Question

The enthalpy of combustion of carbon to carbon dioxide is -394 kJ according to the equation: C (s) + O2 (g) --> CO2 (g) How many kJ of heat are released when 24.0 g of carbon are burned in an excess of oxygen
394 kJ heat released by burning 12 g C; therefore, burning 24 g will release
394 x (24/12) = ?? kJ.
