B. The heat of reaction for the process described in (a) can be determined by
applying Hess's law. The heats of reaction shown in the table below can be
obtained experimentally or looked up in tables of enthalpy data. Which two of
these heats of reaction would be the easiest and safest to measure in the
laboratory, and which two are better obtained through reference sources?
Why? Hint: Consider whether a reaction takes place in aqueous solution or
instead involves noxious gases.
