Find enthalpy of MgO given this information
Hess's Law-Part B indirect In B experiment, we will be finding the enthalpy offormation for Mgos) using an the net method. According to Hess's Law, two or more reactions can be added to give a net reaction, AH for if reaction is simply the sum of the AH 's for the reactions which are added. Consider the following three reactions: AH1 H (1) va (2) Mg caal AH, (3) (4) Notice that when the three reactions are added, they form the formation reaction for Meo. Analogously, when we add the enthalpies for the three reactions, they give the enthalpy change associated with the formation reaction.
