Consider the following types of electromagnetic radiation: (1) ultraviolet, (2) visible, (3) x-ray, (4) microwave, (5) radio waves, (6) infrared.

(a) Arrange them in order of increasing wavelength (from least to greatest).

(b) Arrange them in order of increasing frequency (from least to greatest).

(c) Arrange them in order of increasing energy (from least to greatest).

The answer is b because c don't explain why the moths are on them and it isn't a because as we know only one species of moth does this

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.
