Answer:
A calculated field will appear in the field list window, but will not take up space in the source data. In the example shown, a calculated field called "Unit Price" has been created with a formula that divides Sales by Quantity. The pivot table displays the calculated unit price for each product in the source data.
Explanation:
The PivotTable Field List contains calculated fields. Items from other fields that have been calculated display as items.
What are calculated fields?Calculated fields are defined as the fields whose values are determined by other fields' values and perhaps external sources. Data from other fields can be calculated using calculated fields. Calculating the sum of two fields is a simple example, but more complicated calculations, such averaging values from multiple tables or even gaining access to external data, are theoretically feasible.
PivotTable Field List is defined as the Areas part of the Field List allows you to organize the fields wherever you like. It features a field section where you select the fields you wish to display in your PivotTable. Using a pivot table is an interactive method for quickly summarizing enormous amounts of data.
Thus, the PivotTable Field List contains calculated fields. Items from other fields that have been calculated display as items.

If you have 1 mol xe and 1 mol f₂, how many moles of xef₄ can you create in the following chemical reaction? xe (g) 2 f₂ (g) → xef₄ (g).
The number of moles of XeF4 that can be created would be 0.5 moles.
From the equation of the reactiobn:
Xe (g) 2 F₂ (g) ---> XeF₄ (g)
The mole ratio of Xe to F2 is 1:2. Hence, in the presence of 1 mole Xe and 1 mole F2, F2 would be limiting the reaction.
This means that the amount of F2 would determine the amount of XeF4 that would be produced from the reaction.
The mole ratio of F2 to XeF4 according to the equation is 2:1. This means that for every 1 mole of F2 introduced into the reaction, 0.5 moles of XeF4 will be produced.
In this case, 1 mole of F2 is introduced. Thus, the mole of XeF4 that would be produced would be:
1/2 = 0.5 moles.

Determine the [Ag+] present in solution at equilibrium when the complexing agent ammonia is added to a 0.025 M solution of AgNO3 to result in a [NH3]eq = 0.15 M.
Solubility constant (Ksp) for Ag(NH3)2 2+ is 1.7 * 10^7.
The concentration of [Ag+] present in the solution is 6.53 × 10⁻⁸ M
From the given information, the equation for the reaction between silver ion and ammonia can be represented as:
Ag⁺ + 2NH₃ ↔ [Ag(NH₃)₂]⁺
Given that the solubility constant (Ksp) for the product formed = 1.7 × 10⁷.
The solubility constant for this reaction can be expressed as:
[tex]\mathbf{Ksp = \dfrac{[Ag(NH_3)_2]^+}{[Ag^+][NH_3]^2} }[/tex]
where;
concentration of ammonia = 0.025 Mconcentration of silver nitrate = 0.15 M[tex]\mathbf{1.7 \times 10^7 = \dfrac{0.025}{(x)(0.15)^2}}[/tex]
[tex]\mathbf{1.7 \times 10^7 = \dfrac{1.1111}{x}}[/tex]
[tex]\mathbf{x = 6.54 \times 10^{-8} \ M}[/tex]
Therefore, we can conclude that the concentration of [Ag+] = x = 6.54 × 10⁻⁸ M.

PLS HELP 100 points
The oxidation half equation is Zn ------> Zn^2+ + 2e while the reduction half equation is Cu^2+ + 2e------> Cu.
A redox reaction is a reaction in which there is a loss/gain of electrons. The specie that gives out electrons experiences an increase in oxidation number while the specie that gains the electrons experiences a decrease in oxidation number.
For the reaction; CuCl2 + Zn → ZnCl2 + Cu
The oxidation half equation is;
Zn ------> Zn^2+ + 2e
The reduction half equation is;
Cu^2+ + 2e------> Cu
The chloride ion is excluded because its oxidation number does not change from left to right in the reaction.

Why was einstein not happy with the probable positions of electrons in the orbitals?
Since electron orbitals are described as probability clouds, Einstein disagreement with the probable positions of electrons in the orbitals is that, It is not possible to know the orbit of an electron when the position is under probability.
According to Bohr's theory, it is difficult to locate electron or cannot be located in a definite region. Electron has to be found in an orbit and nowhere else. When the probability of finding an electron in a given spherical shell around the nucleus is plotted the distance of the electron from the nucleus for the hydrogen atom, the graph indicates that the probability of finding the electron increases as the distance between the electron and the nucleus decreases
Bohr claimed that electrons a entities had only probabilities if they weren't observed. While Einstein argued that they had independent reality.
But in wave mechanics Model, there is a slight chance of knowing the location of the electron.
Heisenberg uncertainty principle also claim the possibility of knowing the position of electron. Albert Einstein also claim that; to determine the position of an electron to an accurate extent, you would have to compromise your ability to know it's momentum. This inaccuracy will eventually affect the measurement of momentum which will be extremely uncertain.
Since electron orbitals are described as probability clouds, Einstein disagreement with the probable positions of electrons in the orbitals is that, It is not possible to know the orbit of an electron when the position is under probability.

Find the volume v of the solid obtained by rotating the region bounded by the given curves about the specified line. Y = 8x3, y = 0, x = 1; about x = 2.
The volume v of the solid obtained is 15.08
By using the cylindrical shell method to find the volume v of the solid which can be expressed by the formula;
V = 2πrh drThen, it is paramount to determine the radius and height of the shell.
From the given information;
The cylindrical shell formed by the rotation about the line x = 2Let consider the radius to be 2 - xThe circumference = 2π(2 - x)The height = 8x³Then, the volume v of the solid can be estimated by using the cylindrical shell method as follows;
[tex]\mathbf{V = \int ^1_0 2 \pi (2-x) (8x^3) \ dx}[/tex]
Open brackets;
[tex]\mathbf{V = 2 \pi \int ^1_0 (16x^3 -8x^4) \ dx}[/tex]
Taking the integral form;
[tex]\mathbf{V = 2 \pi \Big [ \dfrac{16x^4}{4}-\dfrac{8x^5}{5} \Big]^1_0}[/tex]
Solving the terms in the bracket
[tex]\mathbf{V = 2 \pi \Big [ \dfrac{16(1)^4}{4}-\dfrac{8(1)^5}{5} -0\Big]}[/tex]
[tex]\mathbf{V = 2 \pi \Big [ 4-\dfrac{8}{5} \Big]}[/tex]
[tex]\mathbf{V = 2 \pi \Big [ \dfrac{20-8}{5} \Big]}[/tex]
