Not sure how to calc the value of Ka
1 AnswerChemistry6 years agoHow much heat is released when 115 g of steam at 100.0°C is cooled to ice at -15.0°C?
How much heat is released when 115 g of steam at 100.0°C is cooled to ice at -15.0°C? The enthalpy of vaporization of water is 40.67 kJ/mol, the enthalpy of fusion for water is 6.01 kJ/mol, the molar heat capacity of liquid water is 75.4 J/(mol ⋅ °C), and the molar heat capacity of ice is 36.4 J/(mol ⋅ °C).
Would someone be willing to show me the steps? I'm a little lost to this problem
