Rocket fuel combustion is mainly to convert chemical energy into heat and light energy, which may pollute the environment D. The thermochemical equation for the combustion of dimethylhydrazine is: C2H8N2 (g) + 2N2O4 (g) = 2N2 (g) + 2CO2 (g) + 4H2O (g); Delta H = - 2550 kj/...
chemical equation (redirected fromChemical equations) Medical Encyclopedia Related to Chemical equations:Chemical Reactions n (Chemistry) a representation of a chemical reaction using symbols of the elements to indicate the amount of substance, usually in moles, of each reactant and product ...
atherefore no energy equation was solved. Mass transfer between phases and chemical reactions were neglected. As mentioned earlier, the interphases drag forces would mainly dominate the motion of bubbles and themagnitude of lift force is much smaller than the interphases drag force. Considering this,...
In a previous paper we derived an equation for the chemical potential of a nonideal, infinitely dilute solute in a van der Waals fluid. From this we also explored the change in the Gibbs energy of transfer of a solute between two van der Waals fluids and explored the effects of using diff...
Using the 1/Zexpansion of the total energyE(Z,N) of atomic ions of nuclear chargeZand havingNelectrons, the chemical potential μ is shown to be approximately related toEby the equation μ=αE+β+γ √δ+4ε0E(i). Here, α and ε0are functions ofNwhich are determined solely by ...
The degradation temperature in high-energy materials is vital, and by predicting, it is possible to prevent the dangers of the degradation of high-energy materials and increase their safety. In this study, the degradation temperature of 63 energetic ionic liquids was investigated based on imidazole...
We find the steady-state solution \({N}_{{{\rm{R}}}^{{{\rm{ss}}}\) from this equation and compute the reaction yield \({N}_{{{\rm{P}}}^{{{\rm{ss}}}/N\). The difference in yield between the condensate and bare case is particularly large when λS ≪ ℏωvib...
