(a)
Interpretation:
The work done in joules if the gas expands against vacuum has to be calculated.
Concept Introduction:
At constant pressure, the exchange of heat between the system and surroundings is called as Enthalpy and its state function.
Enthalpy can be given by the formula,
Where, H=enthalpy
U=internal energy
P=Pressure
V=Volume
The work done on the system or by the system can be calculated from the equation
Where w=work done
P=Pressure
V=Change in volume

- Q5: Label each chiral carbon in the following molecules as R or S. Make sure the stereocenter to which each of your R/S assignments belong is perfectly clear to the grader. (8pts) R OCH 3 CI H S 2pts for each R/S HO R H !!! I OH CI HN CI R Harrow_forwardCalculate the proton and carbon chemical shifts for this structurearrow_forwardA. B. b. Now consider the two bicyclic molecules A. and B. Note that A. is a dianion and B. is a neutral molecule. One of these molecules is a highly reactive compound first characterized in frozen noble gas matrices, that self-reacts rapidly at temperatures above liquid nitrogen temperature. The other compound was isolated at room temperature in the early 1960s, and is a stable ligand used in organometallic chemistry. Which molecule is the more stable molecule, and why?arrow_forward
