Chem. PLease show work. Heat needed to convert.?
Ethanol (C2H5OH) melts at -114 Celsius. The enthalpy of fusion is 5.02 kJ/mol. The specific heats of solid and liquid ethanol are 0.97 J/g K and 2.3 J/g k, respectively. How much heat (kJ) is needed to convert 25.0 g of solid ethanol at -135 Celsius to liquid ethanol at -50 Celsius.
