Summarize your findings in a scientific report. Include your hypothesis, observations, data, and conclusions. Be sure to answer the questions below in your summary as well as including your findings. . • Where is the salt after you filter the mixture? • Why was the sand able to be filtered out? How could you separate the salt from the water? • What other mixtures can be separated by filtering? • Besides filtering, name two other processes that can separate a mixture. • What did you find out from this investigation? Be thoughtful in your answer.

Hydrogen is the most abundant element on the periodic table..hope it .

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.

It is a product
