At room temperature or about 25°C, potassium nitrate (KNO₃) has a solubility of about 38.7 grams per 100 mL of water. At this concentration, the KNO₃ solution is said to be saturated since it already contains the maximum amount of solute that the solvent can dissolve, thus, if you add more KNO₃ salt, it will no longer dissolve. When the solution has less solute than that of the saturation concentration, it is called an unsaturated solution, thus if you add more solute, the KNO₃ salt will still dissolve. If the concentration of the solution is greater than its solubility, the solution is said to be supersaturated, thus, if excess KNO₃ salt is added, crystals will start to form.
Gas chromatography (GC) is a method of separating mixed compounds.
The separation will depend on each compound's retention time. Compounds with
higher molecular weights will elute out slower than those with lower molecular
weight. This is due to their difference in boiling points. The larger the
structure, the higher the boiling point.

The right answer for the question that is being asked and shown above is that: "b. the act<span>ual yield may be different from the theoretical yield because reactions do no always go to completion." This is the statement that is not true about "yield."

The calcium that triggers muscle contraction is stored in synaptic vesicles called endoplastic reticulum. that is not the only function of the endoplastic reticulum it is also a network of a membranous tubules within the cytoplasm of a eucryotic cell continuous with the nuclear membrane.
I think the answer is D :) ........
