Hess's Law says the totalenthalpy changedoes not rely on the path taken from beginning to end. Enthalpy can be calculated in one grand step or multiple smaller steps. To solve this type of problem, organize the givenchemical reactionswhere the total effect yields the reaction needed. There ar...

The work done by the compressor per unit mass of fluid equals the enthalpy change through the compressor. From the definition of enthalpy, calculate the specific work done by knowing the temperature change and the specific heat of the fluid at constant pressure: ...
flash point for a few mixtures of which I am authoring safety data sheets. Most chemicals I am authoring these for I am able to simply copy my suppliers safety data sheet, but we mix 2 or 3 chemicals in house which I will need to know this calculation for in order to classify ...
In general, the densities have benefited from the change in the constants, but the speed of sound and isobaric heat capacities are less well reproduced, especially in the sub- critical temperature range. Finally, the behavior of the isotherms for various long-chain hydrocarbons is examined. ...

Today I've done my first lab experience within the Physical Chemistry 1 course. Our aim was to calculate the ΔH of combustion of the salicylic acid, using as a standard the benzoic acid. We used the Parr Bomb Calorimeter, worked with oxygen at 30 atm and with 400cm3 of water. ...
