a 10 m concentrated stock solution of nacl is used to prepare 3 liters of diluted 1 m solution. which of the following is true for the process used to achieve the required dilution?

the volume of stock solution used is less than 0.2 liters.
the volume of stock solution used is less than 3 liters. (i choose this answer)
the volume of the solvent used is less than 0.2 liters.
the volume of the solvent used is more than 3 liters.

Amines are good nucleophiles, even though they are neutral molecules. how would the rate of an sn2 reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? amines are good nucleophiles, even though they are neutral molecules. how would the rate of an reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? because both reactants in the rate-limiting step are neutral, the reaction will be faster if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will be slower if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will occur at the same rate if the polarity of the solvent is increased. request answer
