where Ψ is the wavefunction, V is the potential energy expressed as a function of the spatial coordinates, E its total energy, 2 is the Laplacian operator, h is Planck’s constant, and m is the mass. Citing this page: Generalic, Eni. "Schrodinger equation." Croatian-English Chemistry Di...
2.ChemistryA written representation of a chemical reaction, in which the symbols and amounts of the reactants are separated from those of the products by an equal sign, arrow, or a set of opposing arrows. For example, NaOH + HCl = NaCl + H2O is an equation. ...

you have seen a few exceptions to this rule earlier in the chemistry book you learned at school.) If you are satisfied that your formulae are correct, balance the equation to show that the Law of Conservation of Mass is observed during the reaction. In our example you can see that the ...
In 1924, Stern made corrections to the theory accounting for the layer of counterions nearest the surface. When quantitative colloid chemistry came into existence, the “Kruyt” school (Verwey and Overbeek, 1948) routinely employed the Gouy–Chapman and Stern theories to describe the diffuse layer...
The conditions that pertain to equilibrium may be given quantitative formulation. For example, for the reversible reactionA⇋B+C, the velocity of the reaction to the right,r1, is given by the mathematical expression (based on the law of mass action)r1=k1(A), wherek1is thereaction-ratecons...
In the Rouse model,55 [62]〈R2(t)〉=6Dcmt+2ℓ2(3kBTπζℓ2t)1/2 where Dcm=kBT/Nζ is the center of mass diffusion coefficient. Figure 34 displays the time-dependent MSD 〈R2(t)〉 obtained from a high-molecular-weight (Mw = 80 000) monodisperse PE–PEP melt at 492 K.56 ...
Inaqueous solutions, it's common to balance chemical equations for both mass and charge. Balancing for mass produces the same numbers and kinds of atoms on both sides of the equation. Balancing for charge means the net charge is zero on both sides of the equation. The state of matter (aq...
