You need to take into account the equations for the average speed and kinetic energy of gases.

Kinetic energy, KE = [1/2] m * v^2

Average speed, v = √[3RT/m] => v^2 = 3RT / m

=> KE = [1/2]m * 3RT/m = [3/2] RT

R = 8,314 J/mol*K

T = 254 K

=> KE = [3/2]*(8,314J/mol*K)*(254K) = 3167.6 J/mol

Answer: 3167.6 J/mol

How could you “supersaturate” solutions, exceeding the amount of dissolved solute possible
Bingel [31]

Answer:

Explanation:

In a saturated solution, more solute cannot be dissolved at a given temperature.

This is because, the solute dissolves in a solvent because of space between particles of solvent but on continuous addition of solute, the space between the solvent particles gets fulfilled. Thus no more solute particle can dissolve in a solvent.

Provide the organometallic reagent that is needed to perform the transformation shown below. The reagent should be formatted as
Juliette [100K]

The correct answer is   LiCH_{3}CH(CH_{3} )CH_{3} .

<h3>Organometallic reagent</h3>

Organometallic chemistry is the study of organometallic compounds, which are substances that contain at least one chemical bond between a carbon atom from an organic molecule and a metal. These substances include alkali, alkaline earth, and transition metals, as well as metalloids like boron, silicon, and selenium. In addition to links to organyl fragments or molecules, bonds to 'inorganic' carbon, such as those to carbon monoxide (metal carbonyls), cyanide, or carbide, are also typically regarded as organometallic. Although they are not strictly speaking organometallic compounds, some similar compounds, such as transition metal hydrides and metal phosphine complexes, are frequently included in discussions of such substances. The phrase "metalorganic compound," which is comparable but different, describes molecules that contain metals but do not have direct metal-carbon bonds but do have organic ligands.

gregori [183]

Answer:

Convection, and boundaries

Explanation:

In this lab, you modeled how plates move. The plates that make up Earth’s lithosphere move because of convection . You also saw how plates interact with each other. The interactions between plates form plate boundaries of which there are three main types.
