If the common element of Fluorine-9 and one of the isotopes is Fluorine-10, what does the -10 tell us about the element and how many protons and neutrons does the element have?

Mary is conducting an experiment on how pollution affects plant growth. how can she ensure that her data are reliable?

What element has similar physical and chemical properties as boron.

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
