Standard enthalpy of formation of Sc5Si3

Metallurgical Transactions B, 1989
The standard enthalpy of formation of Sc5Si3 has been determined by solute-solvent drop calorimetry at (1473±2) K. The following value is reported: ΔH f o (mean)=−(719.1±34.0) kJ mol−1. This result is compared with corresponding published values for the enthalpies of formation of Me5Si3, with Me=Mn, Cr, V, Ti. This comparison shows regularly increasing

Standard enthalpy of formation of diphenyl oxide

The Journal of Chemical Thermodynamics, 2018
Abstract The energy of combustion of a pure sample diphenyl oxide in crystal and liquid states at T = 298.15 K was determined by isoperibolic calorimeter combustion. The enthalpy of fusion, the triple-point temperature and the purity of the sample were estimated by studying the melting process by calorimetric method.

Standard molar enthalpy of formation of vanillin

Journal of Thermal Analysis and Calorimetry, 2017
Specific energy of combustion of vanillin was determined using the bomb calorimeter BIC 100 with high degree of thermal protection from environment impact. The standard deviation of mean for energy equivalent was 0.01%. Based on the specific energy of combustion −(25,072.1 ± 7.4) J g−1, the standard molar enthalpy of combustion and standard molar ...

Standard enthalpy of formation of copper(II) pivalate

The Journal of Chemical Thermodynamics, 2019
Abstract The combustion energy of crystalline copper(II) pivalate was determined by static-bomb isoperibolic calorimetry. The standard enthalpy of formation was calculated on basis of obtained results. The value of standard enthalpy of formation was used to calculate the enthalpy of breaking bond Cu---Piv by the reaction: Cu(C5H9O2)2(cr) = Cu(cr ...
