Answer:The energy of the molecules in the computer decreases.

Explanation:LET ME KNO IM WRONG

Answer: The energy of the molecules decrease in the computer

Explanation:

This is because you turned off the computer cooling it down and slowing the molecules.

Both ionization energy and electron affinity are opposite processes to each other because of their functions.

The main difference between electron affinity and ionization energy is that electron affinity refers to the amount of energy released when an atom gains an electron while on the other hand, ionization energy is the amount of energy required to remove an outermost electron from an atom.

So we can conclude that both ionization energy and electron affinity are opposite processes to each other because of their functions.

Answer:

Have some attraction towards each other

Explanation:

Gases deviate from the ideal gas behavior because their molecules have forces of attraction between them. At high pressure, the molecules of gases are very close to each other so the molecular interactions start operating and these molecules do not strike the walls of the container with full impact.

Explanation:

The atomic number of Uranium is 92. The electron configuration is: [U] = [Rn] 5f3; 7s4 where Radon Rn has 86 electrons and a complete period. This result is respecting the Madelung. BUT … U is an exception !!!

On the period 7 are only 6 electron left for Uranium (92–86). The first 2 electrons are on the principal energy level 7 and occupy the 7s-orbital block. The 3rd electron is placed in the 5f-orbital block. The next 3 electrons are place here as well. The last electron has the unique quantum label (n; l; ml; s) = (5; 3; 0; 0)

To understand this: The first electron of the 5f-orbital block has the label (5; 3, -3; 0). The following electrons have the labels (5; 3; -2, 0), (5; 3; -1; 0), (5; 2; 0; 0). You notice, that the HUND’S RULE is satisfied. ( I always use head 0 before tail 1 to represent the spin.) The f-orbital block is made up of 7 orbitals and therefore can be filled up by at most 14 electrons. When the first electron has the spin 0 then the next 6 electrons must also have the spin 0. With the electron 8 you get the label (5; 3; -3, 1) which tells us, that the spin is opposite to 0. It must be 1. The next 6 electrons also will have spin 1 but are placed in the orbitals -2; -1; 0; 1; 2; 3. Their labels are: (5; 3; -2; 1), (5; 3; -1; 1), (5; 3; 0; 1), (5; 3; 1; 1), (5; 3; 2; 1) and (5; 3; 3; 1) Now the f-block is full !!!

ANSWER: The last electron of U has the label (5; 3; 0; 0). BUT … !!!!!

I hope that you can verify now the correctness of the answer by yourself according to the Madelung.

Please, apply the definitions of the 4 quantum numbers correctly by also respecting the MANDELUNG’S RULE, the OCTET RULLE, the HUND’S RULE.

NOTICE: The Madelung has 21 exceptions. (Wikipedia lists only 20 and treats Ni not as an exception)

Cr, Ni, Cu, Nb, Mo, Ru, Rh, (Pd), Ag, Pt, Au and

La, Ce, Gd, Ac, (Th), Pa, U, Np, Cm, Lr.

In the first group listed: 1 electron moves inwards. In the second group listed: 1 electron moves outwards. Pd and Th have 2 moving electron each. YOU CAN SEE, THAT U IS AN EXCEPTION !!!

CORRECT ANSWER: The last electron of U has the label (6; 2; 0; 0). Can you see the moving electron ??? ❮❮(5; 3; 0; 0) becomes (6; 2; 0; 0)❯❯ Can you see the moving outwards ???

The 21 exception were discovered with spectral analysis. The MADELUNG is not a principle !!! It is only a very simple rule to memorise the electron configurations. By respecting the exceptions, you can correct you Madelung answer !!! Learn the 21 exceptions by heart !

Did you get it ??? (6; 2; 0; 0) is the label of the last electron of U.

According to question ~

The corresponding change in pressure in atm is 0.285 atm.

To solve the question, we need to know what pressure is.

This is the force per unit area acting on a surface.

The change in pressure in the mercury barometer is given by ΔP = ρgh where

So, ΔP = ρgh

= 13600 kg/m³ × 9.8 m/s² × 0.217 m

= 28921.76 kg/m-s²

= 28921.76 N/m²

= 28921.76 Pa

Since 1 atm = 101325 Pa

28921.76 Pa = 28921.76 Pa × 1 atm/101325 Pa

= 0.285 atm

So, the corresponding change in pressure in atm is 0.285 atm.

Answer:

Explanation:

You have the equation. Now change the 3.4 g H2 to moles. moles = grams/molar mass

3.4 g/2.016 = 1.686 moles.

Now using the coefficients in the balanced equation, convert moles H2O2 to moles H2O.

1.686 moles H2 x (2 moles H2O/2 moles H2O2) = 1.686 x (2/2) = 1.686 x (1/1) = 1.686 moles H2O.

Now you know that 1 mole of water is composed of 6.022 x 10^23 molecules. So

1.686 moles H2O x (6.022 x 10^23 molecules H2O/1 mole H2O) = ?? molecules.

The volume of the gas in the chamber is equal to 664.36 L.

The ideal gas law is defined as an equation of the state of an ideal gas. This equation is written as the product of the volume and pressure of 1 mole gas is equal to the product of the gas constant and absolute temperature of the gas.

The mathematical formula of the ideal gas law is as follows:

PV = nRT

Where n is the moles of gas, V is the volume of the gas, R is the gas constant and P is the pressure.

The temperature of the gas in the chamber, T =  26° C = 299 K

The pressure of the gas, P = 3 atm

The value of the gas constant, R = 0.082 atm L/K mol

The number of moles of a given gas, n = 2600/32 = 81.25 mol

Substituting the values n, R, P, and T in the equation, we get:

3 × V = 81.25 × 0.082 × 299.15

V = 664.36 L

[tex]5{Fe}^{ + 2} +1{MnO_4}^{ - 1} + 8 {H}^{ + } \rightarrow 5{Fe}^{ + 3} + 1{Mn}^{ + 2} + 4H_2O[/tex]

Explanation:

To balance any redox reaction the primary factor is to identify the species undergoing oxidation and reduction.

Below are the steps to identify species undergoing oxidation and reduction:

let's calculate oxidation number,

given reaction

[tex]{Fe}^{ + 2} +{MnO_4}^{ - 1} \rightarrow {Fe}^{ + 3} + {Mn}^{ + 2}[/tex]

Of reactant,

[tex]Fe = +2, {MnO_4}^{ - 1} \\ Let \: oxidation \: of \: Mn \: is \: x \: and \: Oxygen -2 \\ {MnO_4}^{ - 1} \rightarrow \: x + 4 \times ( - 2) = - 1 \\ {MnO_4}^{ - 1} \rightarrow \: x + - 8 = - 1 \\ {MnO_4}^{ - 1} \rightarrow \: x = + 8 - 1 \\ {MnO_4}^{ - 1} \rightarrow \: x = + 7 \\ \fbox{ Mn \: +7, O \: -2}[/tex]

Of product,

[tex]\fbox{Fe \: +3, \: Mn \: +2}[/tex]

Now calculate the change in oxidation number

[tex]Fe = +3-(+2) = +1 \\ Mn = +2-(+7) = -5[/tex]

now balance the increase in oxidation number and decrease in oxidation number,

thus we require 5 Fe for 1 MnO4-,

Now putting these numbers as their coefficient,

[tex]5{Fe}^{ + 2} +1{MnO_4}^{ - 1} \rightarrow 5{Fe}^{ + 3} + 1{Mn}^{ + 2}[/tex]

now balance oxygen atom on product side by adding water,

since there are 4 oxygen atoms in reactants 4 water molecules will be there on product side.

[tex]5{Fe}^{ + 2} +1{MnO_4}^{ - 1} \rightarrow 5{Fe}^{ + 3} + 1{Mn}^{ + 2} + 4H_2O[/tex]

now balance Hydrogen atom on reactant side by adding H+ ion, since there are 4 water molecules on product 8 H+ ion will be in reactants!

[tex]5{Fe}^{ + 2} +1{MnO_4}^{ - 1} + 8 {H}^{ + } \rightarrow 5{Fe}^{ + 3} + 1{Mn}^{ + 2} + 4H_2O[/tex]

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Confirming the balanced reaction, by checking number of atoms and charge on reactant vs Product side.

Total number of Fe on reactant and product = 5

Total number of Mn on reactant and product= 1

Total number of Oxygen on reactant and product = 4

Total number of hydrogen on reactant and product= 8

Total charge on reactant side= 5×(+2)-1+8=17

Total charge on product side = 5×(+3)+1×(+2)=17

If 6 units of AB were reacted with 10 units of CD in the described equation, the limiting reactant would AB

They are reactants that determine how far a reaction can go in terms of yield.

From the equation: 3AB + 4CD --> 2AD + 6CB

The mole ratio of AB to CD is 3:4

Thus, 6 units of AB will require 8 units of CD.

But 10 units of CD were reacted with only 6 units of AB. This means that CD is in excess by 2 units while AB will limit the yield of the reaction.

The mass of fluorine that were formed is 592 mg

From the question, we are to determine the mass of fluorine formed

First, we will write the balanced chemical equation for the decomposition reaction

The balanced chemical equation for the reaction is

CaF₂ → Ca + F₂

This means

1 mole of calcium fluoride decomposes to give 1 mole of calcium and 1 mole of fluorine

Now, we will determine the number of moles of calcium produced

From the given information,

Mass of calcium produced = 625 mg = 0.625 g

Using the formula,

[tex]Number\ of \ moles =\frac{Mass}{Atomic\ mass}[/tex]

Atomic mass of calcium = 40.078 g/mol

Then,

Number of moles of calcium produced = [tex]\frac{0.625}{40.078}[/tex]

Number of moles of calcium produced = 0.01559 mole

Since

1 mole of calcium fluoride decomposes to give 1 mole of calcium and 1 mole of fluorine

Then,

0.01559 mole of calcium fluoride will decompose to give 0.01559 mole of calcium and 0.01559 mole of fluorine

∴ Number of mole of fluorine formed was 0.01559 mole

Now, for the mass of fluorine formed

Using the formula,

Mass = Number of moles × Molar mass

Molar mass of fluorine = 38 g/mol

Then,

Mass of fluorine formed = 0.01559 × 38

Mass of fluorine formed = 0.59242 g

Mass of fluorine formed = 592.42 mg

Mass of fluorine formed ≅ 592 mg

Hence, the mass of fluorine that were formed is 592 mg.
