Suppose a substance has a heat of fusion equal to 45 calg and a specific heat of 0.75
the liquid state. If 5.0 kcal of heat are applied to a 50-g sample of the substance at a
temperature of 24°C, what will its new temperature be? What state will the sample be in?
(melting point of the substance = 27°C; specific heat of the sold = 0.48 -
- boiling point of
the substance = 700ºC) Show your work.

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
