40 POINTS
Part D
Scientists have done careful and repeated experiments to determine enthalpy changes for many different chemical
reactions. The accepted reaction enthalpies for the chemical reactions in tasks 1 through 3 are given in the table.
Compare your experimentally determined reaction enthalpies from these tasks with the accepted enthalpies. Are
your results similar to or different from the accepted values? What may have contributed to any differences?
