The graph below shows the radioactive decay of potassium whose half life is 1.25 billion years.

graph with amount of radioactive potassium present (in grams) plotted on y axis and number of half-lives plotted on x axis. the points (0, 1000), (1, 500), (2, 250), (3, 125), and (4, 62.5) have been joined using a smooth curve.

in your own words, summarize the information provided by the graph about the radioactive decay of potassium.

Solubility would be your answer.

True is ur answer : )

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.
