The element bromine is not a reddish-brown liquid. Liquid is the substance bromine.
M=DV
M=3.103 g/mL * 19.8 mL = 61.44 g
In an electrically neuteral atom, number of protons = number of electrons = atomic number.
Mass number = neutrons + protons/electrons/atomic number
Therefore,
neutrons = mass number - <span>protons/electrons/atomic number
Neutrons = 33 - 15 = 18
The answer is thus B. But this is the solution and explanation along with it as proof.</span>
Answer:
To determine the enthalpy and entropy of dissolving a compound, you need to measure the Ksp at multiple temperatures. Then, plot ln(Ksp) vs. 1/T. The slope of the plotted line relates to the enthalpy (ΔH) of dissolving and the intercept of the plotted line relates to the entropy (ΔS) of dissolving.
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us use the thermodynamic definition of the Gibbs free energy and its relationship with Ksp as follows:
![\Delta G=-RTln(Ksp)\\\\\Delta G=\Delta H-T\Delta S](https://tex.z-dn.net/?f=%5CDelta%20G%3D-RTln%28Ksp%29%5C%5C%5C%5C%5CDelta%20G%3D%5CDelta%20H-T%5CDelta%20S)
Thus, by combining them, we obtain:
![-RTln(Ksp)=\Delta H-T\Delta S\\\\ln(Ksp)=-\frac{\Delta H}{RT} +\frac{T\Delta S}{RT} \\\\ln(Ksp)=-\frac{\Delta H}{RT} +\frac{\Delta S}{R}](https://tex.z-dn.net/?f=-RTln%28Ksp%29%3D%5CDelta%20H-T%5CDelta%20S%5C%5C%5C%5Cln%28Ksp%29%3D-%5Cfrac%7B%5CDelta%20H%7D%7BRT%7D%20%2B%5Cfrac%7BT%5CDelta%20S%7D%7BRT%7D%20%5C%5C%5C%5Cln%28Ksp%29%3D-%5Cfrac%7B%5CDelta%20H%7D%7BRT%7D%20%2B%5Cfrac%7B%5CDelta%20S%7D%7BR%7D)
Which is related to the general line equation:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
Whereas:
![y=ln(Ksp)\\\\m=-\frac{\Delta H}{R} \\\\x=\frac{1}{T} \\\\b=\frac{\Delta S}{R}](https://tex.z-dn.net/?f=y%3Dln%28Ksp%29%5C%5C%5C%5Cm%3D-%5Cfrac%7B%5CDelta%20H%7D%7BR%7D%20%5C%5C%5C%5Cx%3D%5Cfrac%7B1%7D%7BT%7D%20%5C%5C%5C%5Cb%3D%5Cfrac%7B%5CDelta%20S%7D%7BR%7D)
It means that we answer to the blanks as follows:
To determine the enthalpy and entropy of dissolving a compound, you need to measure the Ksp at multiple temperatures. Then, plot ln(Ksp) vs. 1/T. The slope of the plotted line relates to the enthalpy (ΔH) of dissolving and the intercept of the plotted line relates to the entropy (ΔS) of dissolving.
