Describe how you would prepare a supersaturated solution.

2 answers:

7 0

First, heat the solute to a high temperature, but not boiling. Next, dissolve the solute into the heated solution until the solute will no longer dissolve. Once that happens, take the heated solution off the heat and allow it to cool. Once the solution is cool you now have a supersaturated solution.

Using a saturation curve, determine how much solute needs to be added to water to make the solution saturated. Then make sure to add more then the amount you found to make the solution supersaturated

Which one of the following statements is correct? A. A pure substance may be separated by filtration or distillation into two or

torisob [31]

Answer: Option (D) is the correct answer.

Explanation:

A pure substance is defined as the substance that is made up of only one type of atom or only one type of molecule.

For example, $Cl_{2}$ is a molecule and it is a pure substance.

Also, substances that contain two or more different element which are chemically combined in a fixed ratio by mass are known as compounds. They are also pure substances.

A pure substance can only be separated by a chemical method and not by any physical method.

A heterogeneous mixture is defined as the mixture which contains non-uniform composition of solute particles into the solution.

For example, mud dissolved in water.

It is not necessary that two or more substance present in a heterogeneous mixture should be of same phase.

Also, it is not necessary that combination of a liquid and a solid always results in a heterogeneous mixture.

If the solid is able to dissolve completely into the liquid then it will result in a homogeneous mixture.

Whereas a homogeneous mixture is defined as the mixture which contains uniform distribution of solute particles into the solvent.

For example, salt dissolved in water is a homogeneous mixture.

Thus, we can conclude that the statement composition is uniform throughout a homogeneous mixture, is correct.

The pressure in a cylinder of nitrogen continuously decreases as a gas is released from it. On the other hand, a cylinder of pro

Juli2301 [7.4K]

Answer:

Explanation:

Nitrogen gas in nitrogen cylinder is in gaseous form only . So when gas is released , pressure decreases because moles of gas in the cylinder decreases .

Propane gas in cylinder is in liquified form . The gas is partially in gaseous and liquid form . So when gas is released outside , pressure decreases inside but due to low pressure , some liquid form is converted into gaseous form which restores the pressure of gas inside cylinder . Hence , the pressure of gas remains unchanged inside cylinder.
