Read the following excerpt from levitt and dubner’s freakonomics. he also believes that employees further up the corporate ladder cheat more than those down below. he got this idea after delivering for years to one company spread out over three floors—an executive floor on top and two lower floors with sales, service, and administrative employees (feldman wondered if perhaps the executives cheated out of an overdeveloped sense of entitlement. what he didn’t consider is that perhaps cheating was how they got to be executives.) which best describes the type of reasoning the excerpt uses? feldman uses deductive reasoning because he works from a generalization to arrive at specific examples. feldman uses deductive reasoning because he arrives at a broad generalization based on another generalization. feldman uses inductive reasoning because he formulates a generalization based on specific examples. feldman uses inductive reasoning because he formulates a generalization based mostly on experience.

29.1-12=17.1the answer is this one

Answerthis solution will not form a precipitateexplanationsolubility equilbrium:         pbf₂(s)  ⇄ pb²⁺(aq) + 2 f⁻(aq)the solubility product expression is    (we exclude solids from the equilibrium expression).now suppose we have the trial ion product q, which we can define as    then, we can interpret  q as the product of the concentration of the ions that we have and ksp as the product of the ion concentrations that are needed to form a saturated solution.if q > ksp, then that implies that there will be a surplus of ions that exceed the amount that is required to form a saturated solution. a precipitate will then form (the precipitate continually  forms until the surplus ions are removed and q is decreased to ksp's value).if q = ksp, the saturated solution that forms is barely saturated and the precipitate will be minimal.if q < ksp, then the ion concentration will not be enough to form a saturated solution (so no precipitate).using our information, we calculate the trial ion product:     since q = 2.7  × 10⁻⁸ < ksp =  4  ×  10⁻⁸, a precipitate will not form.
