What property of enthalpy provides the basis of Hess's law? Explain. What is the change of the enthalpy of 8 kg nitrogen gas when heated from 298 K to 679 K? Given: H2(g) + O2(g) -> H2O(l), DH = 286 kJ What is the enthalpy change for the follo...
Hess’s law is based upon the fact that enthalpy is a state function, or in other words, the enthalpy change of a reaction depends only on the enthalpy of the initial reactants and the enthalpy of the final products formed in the reaction. The path of the reaction does not have any i...
Hess' law What property of enthalpy provides the basis of Hess's law? Explain. A certain reaction has an enthalpy of Delta H = -44 kJ and an activation energy of Ea = 53 kJ. What is the activation energy of the reverse reaction?

In the words of Winston Churchill, "Are we downhearted," No, we arc not! But someone is downhearted! Witness the terrified flight of Hess, Hitler's Number Three Man. And listen to this--listen carefully: "The British nation can be counted upon to carry through to victory any struggle th...
in which it held that physical presence is not required in order to require a remote seller to collect sales tax. The decision explicitly overrules the Court’s long-standing precedent inQuill v. North Dakota and National Bellas Hess, Inc. v. Department of Revenue, which provided that physica...
Using the bond energy data given below, which choice is closest to the enthalpy change for the combustion of one mole of acetylene, C2H2, to form carbon dioxide and gaseous water? C-H, 456 kJ/mol C=C, Assuming the enthalpy of vaporization is 10 kJ/mol and the...
“Being a legacy is kind of like getting the Disney FastPass to go to the front of the line,” says Julie Park, an associate professor of education at theUniversity of Maryland, College Park. “It’s not that you didn’t pay to get in like everyone else, and you probably have p...
