Answer:
Explanation:The final homogenous solution, after cooling it to 40°C, will contain 47 g of potassium sulfate disolved in 150 g of water, so you can calculate the amount disolved per 100 g of water in this way:
[47 g of solute / 150 g of water] * 100 g of g of water = 31.33 grams of solute in 100 g of water.
So, when you compare with the solutiblity, 15 g of solute / 100 g of water, you realize that the solution has more solute dissolved with means that it is supersaturated.
To make a saturated solution, 15 grams of potassium sulfate would dissolve in 100 g of water.

A nanoparticle is larger than an atom. A nanoparticle is usually made from a few hundred atoms. These particles range from 1 nanometers to 100 nanometers. On the other hand an atom ranges from 0.1 nanometers to 105 nanometers. Using the sizes above, one can clearly see and understand that an atom is smaller.
The answer is <span>C. Glucose is an organic molecule.
Glucose is carbohydrate so it cannot be a protein or a nucleic acid. It is an organic molecule. The organic molecule is compound consisting of carbon to which are attached hydrogen, oxygen, and nitrogen. Since, g</span><span>lucose is a simple sugar made up of carbon, hydrogen, and oxygen, it, as well as any other carbohydrate, is the organic molecule.</span>
Answer: 83%
Explanation:
The detailed solution is shown in the image attached. First we must work out the balanced reaction equation because accurate solution of the problem must be based on the stoichiometry of the reaction. From the given concentration and volume of reactants, we calculate the amount of substance reacted hence identify the limiting reactant. Lastly we use simple proportion to obtain the theoretical yield of the precipitate. This is now used to calculate the actual yield as shown in the solution attached.
