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.

when creating a calculated column in a pivottable, where does the calculated field appear?
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.

A sample of gas has a volume of 3.50 L and a pressure of
125 mm Hg. What will the new pressure be when the volume
is decreased to 2.75 L? The temperature stays the same.
Answer:
159.09 mmHgExplanation:
The new pressure can be found by using the formula for Boyle's law which is
[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
From the question we have
[tex]P_2 = \frac{125\times3.50 }{2.75} = \frac{437.5}{2.75} \\ = 159.090909...[/tex]
We have the final answer as

what is the total number of valence electrons in ethyl acetate?
Answer: There are 36 valence electrons.
Explanation:
Two or more than two atoms with different physical or chemical properties can not combine together to form an element. Therefore, the valence electrons of C₄H₈O₂ is 32.
What is element?Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.
A valence electron is a negatively charged particle, located in the outermost shell of an atom, that can be transferred to or shared with another atom. To calculate total valence electrons in C₄H₈O₂, we need to add the individual valence electrons of each element.
Valence electrons of C₄H₈O₂= {valence electrons of C×4}+{valence electrons of H×4}+{valence electrons of O×2}
Valence electrons of C₄H₈O₂= {4×4}+{1×4}+{6×2}
Valence electrons of C₄H₈O₂=32
Therefore, the valence electrons of C₄H₈O₂ is 32.

what is the main use of charcol
Answer:
Charcoal is produced by the incomplete combustion of plant or animal products. The major use of charcoal is for outdoor cooking. The second largest use of charcoal is in industrial applications in the form of activated charcoal. The activation process involves heating the charcoal subjecting it to steam or treating with a chemical to both remove substances that have adhered to it as well as break it down into finer particles and thus increase the surface area. Activated carbon has been used for its adsorptive properties as a ‘universal antidote’ in cases of poisonings, as a filter aid agent, and in decolorization processes.

The equation for the reaction between magnesium and hydrogen is written below
mg+2hcl------mgcl (2)+H (2)
(1) what mass of magnesium would be needed to give 50g of hydrogen? (mg=24, H=1)
(2) what volume would this gas occupy at s.t.p
Answer:
Explanation:
The balanced equation says that we'll get 1 mole of H2 for every 1 mole of Mg. 50 grams of H is 50g/2 g/mole = 25 moles of H2. That means we'll need 25 moles of Mg. Convert that into grams: (25 moles Mg)*(24.3 g/mole) = 607 grams Mg.
At STP, all gases occupy 22.4 liters/miole. That means 25 moles of H2 would occupy (25 moles)*(22.4 liters/mole) = 560 liters.

0.0200 moles of a compound is found to have a mass of 1.64 g. Find the formula mass of the compound
Give your answers to 3 significant figures
Answer: 82.0 g/mole
Explanation:
Use the units to see that if we divide 1.64 grams by 0.0200 moles, we'll get a number that is grams/mole, the definition of formula mass.
1.64/0.0200 = 82.0 g/mole (3 sig figs)
We can't tell from this alone what the molecular formula might be, but C6H10 (cyclohexene) comes close (82.1 grams/mole).
The formula mass of the compound will be approximately 82.0 g/mol
The formula mass of the compound is the sum of atomic masses of all the atoms in its chemical formula. It is calculated by adding up the atomic masses of the individual elements in the compound, each multiplied by the subscript indicating the number of atoms of that element in the formula.
To find the formula mass of the compound, we'll use the relationship between moles, mass, and molar mass.
Molar mass (in g/mol) = Mass (in g)/Moles
Given:
Mass = 1.64 g
Moles = 0.0200 moles
Let's plug the values and calculate molar mass:
Molar mass = 1.64 g / 0.0200 moles
Molar mass ≈ 82.0 g/mol
The formula mass of the compound is approximately 82.0 g/mol, rounded to three significant figures.

Explanation:
type the max number of electrons that can be present in each shell or sub below
n = 5 shell __
n = 2 shell __
n = 2 l = 0 sub: __
n = 2 / 1 sub: __
3d sub: __
2s sub: __
5f sub: __
Explanation:
The maximum no. of electrons in a shell is given by. 2n^2 .
So for
n= 5 , 2× 5× 5 = 50
n=2 , 2×2×2 = 8
For a sub shell the maximum no. of electrons possible is given by 2(2l + 1)
So for n= l= 0
2 [(2×0) +1] = 2
for n=2 l=1
2 [(2×1) + 1] = 6
3d
d sub shell has l= 2 quantum number
Therefore 2[ (2×2) + 1] = 10
2s
s sub shell has l=0 quantum number
2 [(2×0) +1] = 2
5f
f sub energy level has l=3 quantum number
So 2[ (2×3) +1 ] = 14
The azimuthal quantum numbers for the sub shells are as follows
( s ---> 0
p----> 1
d----> 2
f ----> 3 )
