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? Reaction Accepted Reaction Enthalpy, AH CuSO4 + 5H20 = CuSO4.5H2O -78,000 J/mol Zn + CuSO4 = Cu + ZnSO4 -217,000 J/mol H3C6H507 + 3NaHCO3 = Na3C6H507 + 3C02 480,000 J/mol + 3H20​

Achemist wants to extract copper metal from copper chloride solution. the chemist places 0.50 grams of aluminum foil in a solution containing 0.75 grams of copper (ii) chloride. a single replacement reaction takes place. (ii) chloride. a single replacement reaction takes place. which statement explains the maximum amount of copper that the chemist can extract using this reaction? a) approximately 0.36 grams, because copper (ii) chloride acts as a limiting reactant b) approximately 1.8 grams, because copper (ii) chloride acts as a limiting reactant c) approximately 0.36 grams, because aluminum acts as a limiting reactant d) approximately 1.8 grams, because aluminum acts as a limiting reactant
