Fun fact: if the DNA in a single human cell were stretched out (but still in its familiar double helix conformation), it would be approximately 2 meters long. Like dissolves like is a useful rule for deciding if a solute will be soluble in a solvent. It is a physical science under natural sciences that covers the elements that make up matter to the compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances. The answer is intermolecular interactions. If it crystalizes, then the solution is supersaturated. Sex Doctor The intermolecular interactions include London dispersion forces, dipole-dipole interactions, and hydrogen bonding (as described in the previous section). For a reaction 2A + B 2C, with the rate equation: Rate = k[A]2[B](a) the order with respect to A is 1 and the order overall is 1. these forces. Calculate. Dipole-dipole interaction, specifically, will probably not happen, or they at least won't contribute significantly to IMFs. Various physical and chemical properties of a substance are dependent on this force. This general trend of "like dissolves like" is summarized in the following table: Note that every time charged particles (ionic compounds or polar substances) are mixed, a solution is formed. a.
