12 2. A hot air balloon has a volume of 3123 mº, and the temperature inside the balloon is 108.0 °C.
The pressure and outside temperature are 744 Torr and 20.0 °C, respectively. Assuming 28.9
g/mol, determine the amount of payload (kg) that could be lifted by this balloon if the mass of
the balloon is 144 kg. Hot air is the lifting medium in this case. A hot air balloon has a hole in
the bottom to heat the air. This means that both the pressure and the molar mass of air is the
same both inside and outside the balloon.

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
