(Exercise :Atkins physical chemistry 8th p.p71 2.12 (a) Answer : Cp,m = 30 J /K mol and Cv,m =22 J /K mol) To start this question, I first think of the change in temperature is positive, so it is not adiabatic change. W=229 Ar=3.0 mol temp : + 2.55K So i use the form...
What is pH scale in chemistry? The pH is a measure of the concentration of hydrogen ions, the acidity or alkalinity of a solution. The pH-scale is normally between 0 and 14. Aqueous solutions at 25 ° C with a pH of less than 7 are acidic and basic or alkaline solutions are those ...

MOLE (Chemistry)ISODESMIC reactionsSPONTANEOUS generationTHERMODYNAMIC potentialsThe Δ H(NHCO) = 8.6 ± 1 kJ/mol and S = 260.6 ± 5.2 J mol K values have been obtained using the energies of isodesmic reactions within the CBS-Q approximation. Use of the CBS-Q, UMP2...
These effects include changes in mass flows within the furnace, the effect on the refractory, the effect on the furnace's life-time, the fuel efficiency of the furnace, the effect on the chemistry within the furnace, and the degree of NOx reduction. A need therefore exists for a method ...
evaluation of 3 × 3 = 9 configurations. Following Eq. (17) four forcesψ(±h(i)α, ±h(j)β,k)γare required for every entry Φ(i,j,k)αβγ. To conclude, a total of 36 static calculations are necessary to parameterize{\rm{\Phi }}(i,j,\forall k \in {\rm{sc}...
