The following structure shows a cyclohexane ring with two attached methyl groups. imported asset

The "Imported Asset" refers to the image attached to this answer. And this is a true or false question regarding whether the structure shown is a cyclohexane ring containing two attached methyl groups.

The correct answer is TRUE. The ring structure is composed of 6 carbons which makes it a cyclohexane, and there are two methyl groups (-CH3) attached to the ring in the 1- and 3-positions of the ring. The full name of this structure is 1,3-dimethylcyclohexane.

The answer is 323 g.

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.
