The heat of fusion of dichloromethane is . Calculate the change in entropy when of dichloromethane freezes at . Be sure your answer contains a unit symbol. Round your answer to significant digits.

This is an incomplete question, here is a complete question.

The heat of fusion of dichloromethane (CH₂Cl₂) is 6.2 kJ/mol. Calculate the change in entropy ΔS when 345. g of dichloromethane freezes at -95.1 degree C. Be sure your answer contains a unit symbol and the correct number of significant digits.

Answer : The value of change in entropy is 35 J/mol.K

Explanation :

Formula used :

where,

= change in entropy  = ?

= change in enthalpy of fusion = 6.2 kJ/mol

= fusion temperature =

Now put all the given values in the above formula, we get:

Therefore, the value of change in entropy is 35 J/mol.K

a electronegativity decreases beacuse the size of nucleus is bigger.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
