What is the mass of kcl that can be added to1.0 l of a 0.010 m pb2+ solution to start precipitation of pbcl2? assume that addition of kcl does not affect the solution volume. given: ksp for pbcl2= 1.6 × 10–5. molar mass kcl = 74.55 g/mol a) 3.0 g b) 1.5 g c) 0.8 g d) 1.0 g e) 0.2 g

While in europe, if you drive 125 km per day, how much money would you spend on gas in one week if gas costs 1.10 euros per liter and your car’s gas mileage is 32.0 mi/gal? assume that 1 euro=1.26 dollars

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
