The statement is not written clearly, so possible answer is 7.43KJ .

Explanation:

                           ΔH = ΔU + (Δng  )RT

       where,

                  Δng = change in number of gaseous moles in any reaction.

and O2 , so,

              Δng  =12−15=−3.

                           ΔH - ΔU =(−3)RT=(−3)×8.314×298.15J      (T in Kelvin)

                           =>  ΔH - ΔU=7430J=7.43KJ

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop
