Aheat exchanger is used to transfer heat from a steam stream to a chlorine gas stream. 100 kg of steam at 1 bar and 450°c enters the heat exchanger and leaves the exchanger as saturated steam at 1 bar. chlorine gas enters the exchanger at 1 bar and 27.0°c and leaves the exchanger at 132.0℃ assume the heat exchanger is adiabatic. th ecanat r dlaseum dsd what is the specific enthalpy of the inlet steam stream? (use liquid water at 0.01℃ as a reference state.) number what is the specific enthalpy of the outlet steam stream? (use the same reference state.) number kj/ kg se what is the specific enthalpy of the inlet chlorine gas stream? (use chlorine gas at 1 bar and 27.0°c as a reference state.) number kj/mol

There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. in the first step, calcium carbide and water react to form acetylene and calcium hydroxide: cac2 (s) + 2h2o (g) → c2h2 (g) + caoh2 (s) =δh−414.kj in the second step, acetylene, carbon dioxide and water react to form acrylic acid: 6c2h2 (g) + 3co2 (g) + 4h2o (g) → 5ch2chco2h (g) =δh132.kj calculate the net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxide from these reactions. round your answer to the nearest kj .
