What is activation in the context of Hess law?Hess Law:Hess Law shows that the change in enthalpy remains the same (a state function). The enthalpy change is independent upon the path. There are also many other terms that are state function, such as internal energy, entropy etc....
Well, not necessarily; zoning out during lectures is something that we're all guilty of doing because we're human beings. However,this is a class where you really, really need to pay attention to your teacher's explanations.It's hard to self-teach chemistry because you're not just memoriz...
How is Hess's law applied in calculating enthalpy? What conditions must be met by a thermochemical equation so that its standard enthalpy change can be given the symbol DeltaH_f^o (standard enthalpy of formation)? For which one of the following equations is enthalpy of reaction equal to enth...

Thermodynamics:This field of subject analysis a crucial property of chemical systems, that is heat. Transfer of heat can happen in either an open or closed system, but not in an isolated system.Answer and Explanation: Calorimeter It is an equipment which comes into use when we want to ...
Explain how the principle described by Hess's law is critical for metabolism. Why does energy decrease up the trophic levels? What is it about the second law of thermodynamics that requires us to eat food? What is the name given to the ability to maintain a constant internal e...
Systems working within the thermodynamic balance and endowed of irreversibility can be simply considered as complex fluxes of matter and energy, where matter and energy enter the flux and degraded matter with heat leaves the flux, according to the second principle of thermodynamics. These are open,...
