The principal reason for the extremely low solubility of nacl in benzene (c6h6) is the a. increased disorder due to mixing of solute and solvent b. hydrogen bonding in c6h6 c. strength of the covalent bond in nacl d. strong solvent-solvent interactions e. weak solvation of na+ and cl- by c6h6

The principal reason for the extremely low solubility of NaCl in benzene (C₆H₆) is the: e. weak solvation of Na⁺ and Cl⁻ by C₆H₆. 
Solvation is the interaction of solvent (benzene) with molecules or ions (sodium chloride) in a solute. Sodium chloride has ionic bonds and benzene has nonpolar covalent bonds, because of that, solvation is weak.

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).

explanation:

sorry i was late, but i don't know what assignment your talking about, i'm in flvs as well, im in earth space science. but u are behind pace bc every class should be in the 3's or 4'
