From these vapor pressures, enthalpy and entropy changes in the above reactions were determined for the average experimental temperature (1650 K). This, combined with literature thermodynamic data, gives the heats of formation and entropies of the hydroxide gas species at the standard state (1 atm...

Gas-Formation Reaction:As the name implied, it is a reaction in which a gas evolved. We must use the fume chamber and fume hood for this because the gas could occasionally be harmful. Baking soda and lemon juice reacting to produce carbon dioxide is a typical example of...

According to the DSC curves, the enthalpy change (ΔH) of dehydration process can be calculated and was found to be 100.12 kJ mol−1. Besides, we suggested another new method to determine the isokinetic temperature value using spectroscopic data. The surface area of synthesized hydrate and ...
energy of ternary system HMX∙∙∙HMX∙∙∙HMX is not large, that on the cooperativity of H-bonds is notable, which leads to the mutually strengthened H-bonding interaction in solution. This is perhaps the reason for the formation of different conformation of HMX in different solvent...
2024, Journal of Energy Storage Citation Excerpt : TBAF hydrate is a semi-clathrate hydrate commonly used for carbon capture [70,71] and hydrate cold storage [72–74]. Its phase change temperature is 11.8–27.9 °C [75], and the available phase change enthalpy can reach 31.5–219.0 kJ/(...
