[17]. trimix 10/50 is a gas mixture that contains 10% oxygen and 50% helium, and the rest is nitrogen. if a tank of trinix 10/50 has a total pressure of 2.07 x 10^4 kpa, then what is the partial pressure of nitrogen?
a). 1.04 x 10^4 kpa
x b). 8.3 x 10^3 kpa
c). 2.07 x 10^3 kpa
d). 2.07 x 10^4 kpa

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
