    There are 5 enthalpy associated here...3 of them include endothermic steps means heat is absorbed and 2 of them include exothermic steps means heat is released

    For enthalpy of formation to be negative del Hf ...the exothermic steps must be less than endothermic steps...so overall it becomes negative
