The molar heats of fusion and vaporization of ethanol are 7.61 and 26.0 kj/mol, respectively. calculate the molar entropy changes for the solid-liquid and liquid-vapor transitions for ethanol. at 1 atm pressure, ethanol melts at −117.3°c and boils at 78.3°c.

For each of the following compounds, decide whether the compound's solubility in aqueous solution changes with ph. if the solubility does change, pick the ph at which you'd expect the highest solubility. you'll find ksp data in the aleks data tab. compounds does solubility change with ph
