Use the heat of vaporization ( H= 30.91) and the entropy of vaporization [S = 93.2] to calculate the boiling point of liquid bromine.
The enthalpy change for the reaction of 60 mL of ethylene with 60 mL of hydrogen gas (H2) at 1.5 pressure is (Change) H= -0.37 .
I can't seem to figure out these problems
