When Maya visited the Grand Canyon on a school trip she made some observations while standing at the top of the canyon. She saw the river rushing by at the bottom and trees growing in cracks along the cliffs. She felt how windy it was at the top and how cold it got at night. She heard rocks fall and roll down the cliffs to the bottom. Which of Maya’s observations is an example of only erosion taking place?

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
