    5. When ethanamide (CH3CONH2) burns inoxygen the carbon is converted into carbon dioxide, the hydrogen is convertedinto water and the nitrogen forms nitrogen gas.
    Enthalpy of formation (DH[img]file:///C:/Users/%EC%9A%B0%EB%A6%AC%EC%A7%91/AppData/Local/Packages/oice_15_974fa576_32c1d314_16ad/AC/Temp/msohtmlclip1/01/clip_image002.png[/img]) /kJ mol–1
    ethanamide –320
    carbon dioxide –394
    water –286
    Using the data above,which one of the following is a correct value for the enthalpy of combustion ofethanamide?
    A –1823kJ mol–1B –1183kJ mol–1C –1000kJ mol–1D –360kJ mo1–1

    Help !!Thank you so much

    Yes i did, but i didn't know how to work out the enthalpy of combustion of ethanamide just by using value of enthalpy of formation

    Write out the equation for the combustion of ethanamide and draw a Hess Cycle.
