Which product is made up of fatty acids that are derived from alkenes?
margarine
polystyrene cups
pain relievers
rubber tires

Answer;

Margarine

Explanation;Margarine are manufactured from animal or vegetable fats and oils through a process called hydrogenation Hydrogenation of alkenes is the process that result to the formation of margarine. Alkenes are unsaturated hydrocarbon that contain a carbon-carbon bond.Hydrogenation of alkenes involves reaction of the carbon-carbon double bond with hydrogen in the presence of a metal catalyst normally, nickel catalyst.

The correct answer is c

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.
