Which answer below correctly identifies the type of change and the explanation for the change in calcium carbonate?
physical change because even though a state change was observed, the calcium carbonate
retained its original properties
physical change because even though a particle size change was observed, the calcium
carbonate retained its original properties and was not transformed into a new substance
chemical change because a state change was observed, which indicated that the calcium
carbonate was transformed into a different substance
chemical change because a particle size change was observed, which indicated that the calcium
carbonate was transformed into a different substance
C

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
