A mixture of CH4 and C2H6 (both are gases) has a total pressure of 0.53 atm. Just enough O2 is added to the mixture to bring about complete combustion of each reactant to gaseous products. The total pressure of the product gases is 2.2 atm. Assuming constant volume and temperature, find the mole fraction of CH4 in the mixture.

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
