The following information is given for benzene, C6H6, at 1atm: boiling point = 80.1 °C Hvap(80.1 °C) = 30.7 kJ/mol specific heat liquid = 1.74 J/g°C At a pressure of 1 atm, what is H in kJ for the process of condensing a 24.8 g sample of gaseous benzene at its normal boiling point of 80.1 °C. kJ

The heat required for the process is 4.24 kJ

Explanation:

To calculate the number of moles, we use the equation:

Given mass of benzene = 24.8 g

Molar mass of benzene = 78.11 g/mol

Putting values in above equation, we get:

To calculate the enthalpy change of the reaction, we use the equation:

where,

= amount of heat absorbed = ?

n = number of moles = 0.318 moles

= enthalpy change of the reaction  = 30.7 kJ/mol

Putting values in above equation, we get:

Hence, the heat required for the process is 4.24 kJ

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

a polar bond is formed when electrons are shared unevenly between atoms
