There is a material on Earth that undergoes a very long, and sometimes violent, cycle.
This material can begin as a solid on the surface of the Earth. Weathering can then break the material up into pieces, and erosion
can transport the pieces to ocean bottoms. Eventually, the material reforms as these pieces are cemented together.
Over time, the material is gradually pushed into the Earth's interior. Heat from inside the Earth can then cause the material to melt
Eventually, the melted material returns back to the surface through volcanic eruptions. At the surface, the material cools and tums
solid once again
What is this material?

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
