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?

CuSO4 + 5H20 = CuSO4.5H20
-78,000 J/mol
Zn + CuSO4 = Cu + ZnSO4
-217,000 J/mol
H3C6H507 + 3NaHCO3 = Na3C6H5O7 + 3CO2 + 3H20 480,000 J/mol

Ill give brainiestif one neutron initiates a fission event that produces two neutrons in the products, how many new reactions can now be initiated? if each of the neutrons produced in the first fission event then initiates a fission event that produces one neutron in the products, how many new reactions can now be initiated by each neutron? how many neutrons in total were produced by the two fission events described?
