Further studies will refine how much water is needed for endangered species protection. States hope it will be the 130-150 KAF initially agreed upon rather than the 415 KAF the FWS thinks it is. What happen if cooperative agreement fails?
the normal boiling point of menthanol is 64.7 degrees celcius, and its molar enthalpy of vaporization is 71.8 kj/mol. Calculate the value of delta S when 1.00 mol of CH3OH (liquid) is vaporized at 64.7 degrees celcius.
