The standard enthalpy of formation at 298.15 K of the aqueous peroxymonosulfate ion, HSO 5 −, has been determined by reduction of the ion in aqueous HI. The value obtained is ΔH f o(HSO 5 −, aq) = −(798.4 ± 2.5) kJ·mol −1. This enthalpy was combined with an estimat...
The molar enthalpies of a solution of ZrMo2O8, Mo, and ZrF4 in 10 mol dm3HF(aq)+4.41 mol dm3H2O2(aq) have been measured using an isoperibol-type calorimeter. From these results and other auxiliary data, the standard molar enthalpy of formation of ZrMo2O8 has been calculated to be ...
Standard enthalpy of combustion values can be found in the Chemistry data booklet. All enthalpy of combustion reactions are exothermic and their enthalpy change is given a negative sign. Standard conditions are: Pressure, P = 1.01 x 10 5 Pa (or 1atm), Temperature, T = 298 K (or 25˚C...
The molar enthalpies of solution of CdMoO4(s), CdO(s), Na2 MoO4(s) and NaF(s) in (10 mol HF(aq) + 4.41 mol H2O2(aq)) dm−3 have been measured using an isoperibol type calorimeter. From these results and other auxiliary data, the standard molar enthalpy of ...
