What is the reaction of hypochlorous acid?
Hypochlorous acid reacts readily with amino acids that have amino group side-chains, with the chlorine from HClO displacing a hydrogen, resulting in an organic chloramine. Chlorinated amino acids rapidly decompose, but protein chloramines are longer-lived and retain some oxidative capacity.
What is the entropy of Cl2?
The standard molar entropy of Cl2 is 223.08 J. mol.
What is the entropy of H2?
Entropy of gas at standard conditions (298.15 K, 1 bar.) S°gas,1 bar (J/mol*K) 130.680 ± 0.003.
What is the entropy of O2?
205.0

What is the enthalpy of dissolution of KCl?
The enthalpies of hydration for potassium and chloride are -322 and -363 kJ/mol respectively. From these values, estimate the enthalpy of solution for KCl. The enthalpy of solution given above is -17.22. The two values here indicates that dissolving KCl into water is an endothermic reaction or change.
Is dissolution of KCl spontaneous?
The overall change in entropy is positive, which is why the dissolution is spontaneous at the given temperature.
Is HClO and HOCl the same?
HOCl and HClO are exactly same. This is molecular formula of hypochlorus acid. It is an oxyacid of chlorine molecule. It is a weak acid which gives .
What is the entropy of Fe2O3?
87.404 J/K
According to standard tables2 the entropy (at room temperature 298.15 K and at pressure 105 Pa) of one mole of Fe is 27.280 J/K, of one mole of O2 is 205.147 J/K, and of one mole of Fe2O3 is 87.404 J/K.
