Base ur answers to questions 1 through 5 on an element that has 15 protons, 16 neutrons. This element has 2 electrons in the innermost energy level, 8 electrons i n the next energy level, and 5 electrons in the outermost energy level. 1) complete the elements structure diagram on the right?
2)what is the elements atomic number?
3) what is the elements mass number?
4)What is the elements chemical symbol?
5) what is the elements chemical name?

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.

Answer the air near the ground cools to its dew point

This is a solution, hope i could
