consider three identical flasks with different gases. in which flask will the molecules have the greatest average velocity

Answers

The flask A, flask B, flask C, all have equal average kinetic energy at 0°C.

What is the average kinetic energy?

The average kinetic energy of the particles in a gas is inversely related to its temperature. These particles must move more quickly as the gas warms because their mass is constant.

KE avg = 3/2RT

As a result, it is possible to state that average kinetic energy depends on temperature. As a result, as the temperature rises, the gas molecules become more energetic and move at a faster rate.

The average kinetic energy also stays the same because, in accordance with the question, the temperature is constant across all flasks.

Therefore, the average kinetic energy of flasks A, B, and C at 0°C is the same.

The movement of the liquid in a thermometer shows changes in temperature. An increase in temperature indicates the molecules in the liquid (A) moved slower and closer together (B) contracted in size when heated (C) moved faster and spread farther apart (D) expanded in size when heated

Answers

(C) moved faster and spread farther apart

An increase in temperature indicates the molecules in the liquid move faster and spread farther apart. The mercury thermometer was named after physicist Daniel Gabriel Fahrenheit in Amsterdam. Mercury thermometers are useful in many ways such as measuring body, liquid, and vapor temperature. The movement of the liquid in a thermometer shows changes in temperature. With an increase in temperature shows the molecules in the liquid are moving faster and the temperature is rising in the thermometer. The mercury expands to indicate a higher temperature up the tube which is marked in order to recognize a measurement of temperature. Mercury thermometers are rare today as most of them are toxic nowadays. A Mercury thermometer consists of a bulb containing mercury attached to a glass tube; the volume of mercury in the tube is much less than the volume in the bulb.

Baed on the preure information in the data table, how are the preure of light and heavy particle related to the preure of the mixed particle?

Answers

Based on the pressure information in the data table, the pressure of light and heavy particle related to the pressure of the mixed particle having same pressure and same volume.

Why do heavy and light particles experience the same pressure?

The lighter H₂ molecules will hit the walls more frequently and with less force because they move faster and collide with them more frequently. Because both light and heavy molecules hit the walls with roughly the same average kinetic energy at the same T, their pressure and consequent volume will be equal.

As the temperature increases, the particles gain energy and accelerate their motion. The movement of heavier particles is slower than that of lighter ones at the same temperature. Both the environment and the particles' mass affect their actual average speed.

How many liters of. 225 M Na2S solution would be required to react completely with 81. 8 g Fe(C2H3O2)3? (The molar mass of iron (III) acetate is 233. 00 g/mol. )

Answers

0.002 liters of 225 M Na2S solution is required to completely react with 81.8 g Fe(C2H3O2)3

Starting from the balanced equation of the reaction and the molar mass of iron (III) acetate (Fe(C2H3O2)3, first the reacting moles of this compound are determined, then the amount of reacting moles of sodium sulfide (Na2S) is determined and finally the amount of solution that contains said amount of moles.

Balanced equation of the reaction

3Na2S + 2Fe(C2H3O2)3 → 6NaC2H3O2 + Fe2S3

Determination of liters of 225 M Na2S solution for a complete reaction

This determination is made in three steps:

Determination of reactant moles of Fe(C2H3O2)3Determination of the reactant moles of Na2SDetermination of the volume of solution with the number of reacting moles of Na2S

Determination of reactant moles of Fe(C2H3O2)3

If 233.00 g of Fe(C2H3O2)3 is equivalent to 1 mol of Fe(C2H3O2)3

So 81. 8 g Fe(C2H3O2)3 equals x mol of Fe(C2H3O2)3

X mol of Fe(C2H3O2)3 = 81. 8 g Fe(C2H3O2)3 x 1 mol of Fe(C2H3O2)3 / 233.00 g of Fe(C2H3O2)3

X mol of Fe(C2H3O2)3 = 0.351 mol

Determination of the reactant moles of Na2S

If 2 moles of Fe(C2H3O2)3 react with 3 moles of Na2S

Then 0.351 mol of Fe(C2H3O2)3 reacts with x mol of Na2S

X mol of Na2S = 0.351 mol Fe(C2H3O2)3 x 3 mol of Na2S / 2 mol of Fe(C2H3O2)3 = 0.526 mol

Determination of the volume of solution with the number of reacting moles of Na2S

If there are 225 moles of Na2S in 1 liter of solution

So there are 0.526 moles of Na2S in x liter of solution.

X liter of solution = 0.526 mol of Na2S x 1 liter of solution / 225 mol of Na2S = 0.0023 liters, that is, 2.3 ml

Therefore, 0.0023 liters of 225M Na2S solution is required.

What is the limiting reactant if you are using 25. 0 grams of phosphorus and 50. 0 grams of oxygen?


A. ) O2


B. ) P4


C. ) P4O10


D. ) P4O2

Answers

The limiting reactant is O2.

To determine the limiting reactant, we need to compare the number of moles of each reactant present.

First, we convert the given masses of phosphorus and oxygen to moles:

25.0 g of P4 = 25.0 g / (123.8 g/mol) = 0.202 mol

50.0 g of O2 = 50.0 g / (32.00 g/mol) = 1.5625 mol

Next, we use the balanced equation for the reaction to determine the stoichiometry of each reactant:

P4 + 5O2 → P4O10

From the equation, we can see that for every one mole of P4, 5 moles of O2 are required.

We can then compare the number of moles of each reactant present:

0.202 mol P4 / 1 mol P4 = 0.202

1.5625 mol O2 / 5 mol O2 = 0.3125

We can see that the number of moles of O2 is less than the number of moles of P4 required by the reaction, so the limiting reactant is O2.

Lattice energy is a measure of the strength of the electrostatic attraction between the positively charged cations and negatively charged anions in an ionic compound. The greater the lattice energy, the stronger the electrostatic attraction and the more stable the compound.The most common method for determining lattice energy is the Born-Haber cycle. This method uses thermochemical data of the individual steps in the formation of an ionic compound to calculate the lattice energy. However, it is often impractical to use this method in a test environment, so a more practical method that is used to compare lattice energies of different compounds is the use of the Coulomb's law which relates the lattice energy to the charge product of the cations and anions and the distance between them.

As an ionic solid dissolves in water, the temperature of the solution increases. What best describes the enthalpy and entropy of the solution

Answers

The water solution gets hotter when an ionic solid dissolves in it. Entropy increases and there is a decrease in enthalpy change.

The spread of the solute molecules (and the thermal energy they carry) through the larger volume of the solvent during the dissolution of a solute typically results in a rise in entropy. When a liquid or solid dissolves in a solvent, entropy typically rises. Less negative entropy change is occurring (or perhaps even at this stage, positive). The chemicals will likely become more soluble as a result. The total result is a delicate balancing act between how the solution's enthalpy changes and how its entropy changes. When a substance is divided into several pieces, entropy rises. Entropy is raised via the disintegration process.

What element has a number of electrons 14?

Answers

The element that has a number of electrons 14 is silicon.

Any material that is totally composed of the same kinds of atoms is said to be an element. For instance, the element carbon is made up entirely of carbon atoms. The number of protons in an atom is indicated by the element's atomic number. The quantity of protons and electrons inside a neutral atom must match.

An element's position on the periodic table is also indicated by its atomic number.

An element possesses 14 electrons, as stated in the question. Since this suggests that it must contain 14 protons, its atomic number must be 14.

In order to locate the element, we must first put down any potential electronic configurations for the element:

1s²2s²2p⁶3s²3p²

In the outermost shell, there are four electrons. The element therefore has 4 electrons in its valence shell. Therefore, this element's period number is 4.

Additionally, the element's group number will be equivalent to:

(Valence electrons + 10) or (4 + 10) equals the 14th group

The element is a p-block element as a result. And silicon is the element that corresponds to the 14th group and 4th period of the periodic table.

Thus, silicon, which possesses 14 electrons, is the correct answer.
