3. Silver has a lower molar heat of fusion compared to that of
gold. Why did the silver sample require the most added heat
to melt?

Respuesta :

Answer:

Because silver weighs less than gold and it has less mass so its easier to melt

Explanation:

Answer:

Because during the observation, 2 moles of gold were present, while 4 moles were added to silver.

Explanation:


In the chart, the amount of moles of silver was more than the moles of gold.....therefore it takes more heat to melt all 4 moles of silver versus only 2 moles of gold.


The molar fusion of gold is 12.6, and the molar fusion of silver is 11.3. When adding the moles as seen in the chart, we simply multiply both elements by their according moles:


12.6 kJ/mol x 2–> 25.2 kJ/mol of gold.

11.3 kJ/mol x 4–>45.2 kJ/mol of silver.
