La densidad de un bulto de maíz es de 0.73 g/cm3. Se le encarga a usted calcular las dimensiones requeridas de los recipientes cilíndricos, en los cuales se desean
almacenar 150 Kg del grano; teniendo en cuenta además que por especificaciones de
resistencia se recomienda que la altura del cilindra sea un 30% mayor que el diámetro
del mismo [volumen del cilindro; V=π·r2 h, d=2r].

Iwould you figure it out but you don't have a picture or in your question as to what the physical property you're looking for is

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.
