Answer:
![\Delta _{fus}H=205J/g=13.03kJ/mol](https://tex.z-dn.net/?f=%5CDelta%20_%7Bfus%7DH%3D205J%2Fg%3D13.03kJ%2Fmol)
Explanation:
Hello there!
In this case, since the heat of fusion is a property that allows us to calculate the heat involved during the change from solid to liquid (fusion) and is calculated as shown below:
![Q=m*\Delta _{fus}H](https://tex.z-dn.net/?f=Q%3Dm%2A%5CDelta%20_%7Bfus%7DH)
In such a way, given the heat involved during this process and the mass of copper, we calculate the heat of fusion as shown below:
![\Delta _{fus}H=\frac{Q}{m}=\frac{41000J}{200.g}\\\\\Delta _{fus}H=205J/g](https://tex.z-dn.net/?f=%5CDelta%20_%7Bfus%7DH%3D%5Cfrac%7BQ%7D%7Bm%7D%3D%5Cfrac%7B41000J%7D%7B200.g%7D%5C%5C%5C%5C%5CDelta%20_%7Bfus%7DH%3D205J%2Fg)
Or in kJ/mol:
![\Delta _{fus}H=205\frac{J}{gCu}*\frac{63.546 gCu}{1molCu}\\\\ \Delta _{fus}H=13026.93J/mol=13.03kJ/mol](https://tex.z-dn.net/?f=%5CDelta%20_%7Bfus%7DH%3D205%5Cfrac%7BJ%7D%7BgCu%7D%2A%5Cfrac%7B63.546%20gCu%7D%7B1molCu%7D%5C%5C%5C%5C%20%20%5CDelta%20_%7Bfus%7DH%3D13026.93J%2Fmol%3D13.03kJ%2Fmol)

Answer:
A
Explanation:
because it can share and remain with ither electrons
Answer:
Hexane
Explanation:
Generally, leucine is hydrophobic in nature and it has a carbon-hydrogen side chain. Therefore, it is not advisable to use an hydrophobic solvent because the leucine zipper would interact with both the opposite alpha helix and the solvent. This will ultimately hinder the dimer creation. Thus, the best solvent which is the least polar in the list is hexane.
9 mL
Explaination:
V1= m2*v2/m1 = 60 x 0.15 /1 = 9 mL
