Question

according to hesss law, if a series of intermediate reactions are combined, the enthalpy change of the overall reaction is
the product of the
enthalpy changes
of the
intermediate
reactions.
the fraction of the
individual
enthalpies of the
intermediate
reactions.
the difference
between the
enthalpies of the
intermediate
reactions.
the sum of the
enthalpy changes
of the
intermediate
reactions.

Explanation:

Hess's law states that the total enthalpy change for an overall reaction is equal to the sum of the enthalpy changes of the individual intermediate reactions that make up the overall process, regardless of the path taken.

Answer:

the sum of the enthalpy changes of the intermediate reactions.
