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...
In any chemical reaction, the enthalpy change is a prominent factor. It is also known as the reaction heat or the enthalpy change of a chemical reaction. In this article, we will study about Hess’s Law of Constant Heat Summation in detail. Scroll down to find out....
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?

Electrolysis and Faraday's Law This unit is huge by itself, and now you're telling me there are eight more??? Sigh. Another day another dollar. The 6 Scientific Practices of AP Chemistry These six "scientific practices" represent skills that students are expected to learn in AP Chemistry.Ma...
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...
Since the DAT blends theoretical knowledge with practical application, understanding both is essential for Test Day success. For the Survey of Natural Sciences, knowing the reason why intermolecular bonds form is just as important as being able to calculate the energy required to break them. You ma...
“You Can’t Watch This” is the new must have DVD that covers Big Tech’s war against Free Speech. You can bear witness to the silencing of conservatives worldwide and what it means for you. Featuring interviews by so-called “dangerous” people like Gavin McInnes, Paul Joseph Watson, ...
obeying conservation of “atoms”. In particular, these realizations can be chosen such that any two species have distinct sum formulas, unless\mathbf {S}implies that they are “obligatory isomers”. In terms of structural formulas, every compound is a labeled multigraph, in essence a Lewis form...
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...
