Answer:

$\Delta _{fus}H=205J/g=13.03kJ/mol$

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:

$Q=m*\Delta _{fus}H$

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:

$\Delta _{fus}H=\frac{Q}{m}=\frac{41000J}{200.g}\\\\\Delta _{fus}H=205J/g$

Or in kJ/mol:

$\Delta _{fus}H=205\frac{J}{gCu}*\frac{63.546 gCu}{1molCu}\\\\ \Delta _{fus}H=13026.93J/mol=13.03kJ/mol$

Regards!

Which substance is most soluble in water? <br> 1) (NH4)3PO4<br> 2)Cu(OH)2<br> 3) AG2SO4<br> 4) CACO3

ivann1987 [24]

Answer: Option (1) is the correct answer.

Explanation:

When dissolved in water, ammonium phosphate $(NH_{4})_{3}PO_{4}$ completely dissociates into ions and it gets attached to the opposite ends of water.

Therefore, it is soluble in water.

Whereas silver sulfate $(Ag_{2}SO_{4})$ slightly dissolves into water as it gives very less $Ag^{+}$ ions. Therefore, silver sulfate has low solubility.
