How do you calculate H from Q?
Feb 20, 2017 · I guess in simpler terms you can say q = heat in general, whereas H (enthalpy) = qp which is heat at a constant pressure.
Jan 29, 2023 · If q is negative, then ΔH will also be negative. Enthalpy Change Accompanying a Change in State. When a liquid vaporizes the liquid must absorb ...
H = q/n. Where: H = Enthalpy Change q = Energy Change n = Moles of reactant ... H = q/n = 3762/0.0195 = -192900 JMol-1 = -192.9 kJmol-1. Don't forget the ...
Mar 17, 2016 · Defining Enthalpy, calorimetry, and showing how to solve problems involving the heat of chemical and physical change.
Feb 29, 2016 · Enthalpy and heat are entirely different things. Enthalpy is a function of state. If you know the state of a system, you know its enthalpy.
Jun 10, 2022 · q refers to the amount of heat transferred. Can't directly measure H so we burn stuff to try and indirectly measure it. The example you ...
Apr 17, 2020 · The answer depends on if you assume the work to be positive or negative. If the work is done on the object of focus you get delta U = Q + W. If ...
The heat given off or absorbed when a reaction is run at constant pressure is equal to the change in the enthalpy of the system. delta Hsys = qp. 3. The change ...
They are the same formula, just in different form. You do however need to understand, that "c" in the formula, stands for specific heat capacity, which is the ...
