    26 lip 2022 · If a distance metric has an upper-bound value greater than 1, (e.g., Euclidean or Hamming distance), the following equation can be used to convert the dissimilarity score to the similarity score: According to this equation, if two molecules are identical to each other, the distance ( D AB ) between them is zero, and their similarity score ( S ...

    Coulomb's law states that the force of attraction between cation and anion is inversely proportional to the square of the distance between them. Since the distance between Mg2+ and OH is shorter than the distance between sr2+ and OH , the attractive forces in Mg(OH)2 are stronger and, therefore, its lattice energy is greater.

    An additional 1 point was earned for identifying the attraction of dye C to the nonpolar solvent. The response earned 2 points in part (b). The student correctly identifies the unknown as dye A and gives the correct ratio of the distance traveled by the solvent front to the distance traveled by the dye.

    The valley (or most negative energy) represents the ideal distance the two nuclei are from each other in the molecule. It’s at that distance that the molecules have the least energy and are the most stable.
