The compound nonane, C9H20, is a good fuel. It is a liquid at ordinary temperatures. When the liquid is burned, the reaction involved isThe standard enthalpy of formation of liquid nonane at 25 °C is -274.7 kJ mol-1; other relevant enthalpy of formation values in kJ mol-1 are:C9H20(g) = -228.2 ; CO2(g) = -393.5 ; H2O(g) = -241.8(a) Calculate the enthalpy change in the burning of 3.000 mol liquid nonane to form gaseous products at 25°C. State explicitly whether the reaction is endothermic or exothermic.endothermicexothermic(b) Would more or less heat be evolved if gaseous nonane were burned under the same conditions?
