Question
The following information is given for antimony at 1atm: Th = 1440.00°C ΔΗ, vap (1440.00°C) = 1.605 x 10³ J/g Tm = 631.00°C Specific heat solid = 0.2090 J/g °C Specific heat liquid = 0.2590 J/g °C AHfus (631.00°C) = 161.1 J/g A 40.40 g sample of liquid antimony at 721.00°C is poured into a mold and allowed to cool to 25.00°C. How many kJ of energy are released in this process? (Report the answer as a positive number.) Energy = kJ
