Many years ago engineers built a canal to control water flow along a river. at the time of building the canal, the engineers did not know that they used a rock that contained iron particles. over time, the rocks have been exposed to a constant supply of water which has given the rocks an orange-brown color. it has formed a new compound called limonite. what type of weathering has occurred to these rocks?

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
