Unformatted text preview: 150.0 g of water at 20.0 ° C. If the temperature of the water rises to 21.4 ° C, what is the specific heat capacity of the stainless steel? (The specific heat capacity of water is 4.184 J/(g· ° C)) (2) Consider the explosive formation of H 2 O( ℓ ): 2H 2 (g) + O 2 (g) → 2H 2 O( ℓ ) Calculate the enthalpy change for this reaction given that: H 2 O ( ℓ ) → H 2 (g) + ½O 2 (g) Δ H ° = 285.8 kJ (3) For a certain reaction at constant pressure, Δ U = -125 kJ and 22 kJ of expansion work is done by the system. What is Δ H for this process?...
