Answer:
Because the value of K is huge.
Explanation:
The tautomer is a kind of isomer in which exist an equilibrium between a ketone and an enol, or between an aldehyde and an enol. So, in the enolization, the ketone is the reactant and the enol is the product.
The equilibrium reaction can be characterized by an equilibrium constant, which is the ratio of the concentration of the products by the concentration of the reactants.
Because the constant K is extremely large (10¹³) we can conclude that the concentration of the product will be greater than the concentration of the reactant, in the equilibrium. It means that the concentration of the enol will be greater.
So, the ketone is unstable and forms in a great amount the more stable product, the enol.
Answer:
The table tennis balls represent neutrons that are released when the nucleus splits and cause other nuclei to split
Explanation:
Nuclear fission is defined as the separation of a nucleus into two smaller nuclei.
It takes a neutron to set off a nuclear fission reaction. When that occurs, neutrons are released and those neutrons in turn are what set off other nuclear fissions. This is defined as a Nuclear Fission Chain Reaction. In the model, the one tennis ball that will be thrown will be modeled as the starting neutron that sets of the initial (first) fission. The mouse traps with tennis balls represent the other nucleuses waiting to be struck by the one tennis ball. Once the initial tennis ball strikes the first mouse trap, that mouse trap will release its tennis ball hitting others and continuing the cycle.
It can also be modeled as such:
The reactant is dissolved in water
A gas and a liquid are produced
Answer:
As Per Given Information
Given mass of H₂O₂ ( Hydrogen Peroxide) 4.0 gm
We've been asked to find the number of moles in Hydrogen Peroxide .
First we calculate molecular mass of Hydrogen Peroxide .
Molecular mass of H₂O₂ = 1×2 + 16 × 2
Molecular mass of H₂O₂ = 2 + 32
Molecular mass of H₂O₂ = 34 gm
Now find the number of moles in given hydrogen peroxide .
![\diamond{\boxed{\blue{\bf{Number \: of \: moles \: = \frac{Given \: mass}{Molecular \: mass} }}}}](https://tex.z-dn.net/?f=%20%20%5Cdiamond%7B%5Cboxed%7B%5Cblue%7B%5Cbf%7BNumber%20%5C%3A%20of%20%5C%3A%20moles%20%5C%3A%20%20%3D%20%20%5Cfrac%7BGiven%20%5C%3A%20mass%7D%7BMolecular%20%5C%3A%20mass%7D%20%20%7D%7D%7D%7D%20)
Put the given value we obtain
![\sf \twoheadrightarrow \: Number \: of \: moles \: = \frac{4}{34} \\ \\ \sf \twoheadrightarrow \: Number \: of \: moles \: =0.117](https://tex.z-dn.net/?f=%20%5Csf%20%5Ctwoheadrightarrow%20%5C%3A%20Number%20%5C%3A%20of%20%5C%3A%20moles%20%5C%3A%20%20%3D%20%20%5Cfrac%7B4%7D%7B34%7D%20%20%5C%5C%20%20%5C%5C%20%5Csf%20%5Ctwoheadrightarrow%20%5C%3A%20Number%20%5C%3A%20of%20%5C%3A%20moles%20%5C%3A%20%20%3D0.117)
So, the number of moles is 0.117 .
The atomic mass of a certain element is summation of the product of the decimal equivalent of the percentage abundance and the given atomic mass of each of the isotope. If we let x be the percentage abundance of the 86 amu-isotope then, the second one is 1-x such that,
x(86) + (1 - x)(90) = 87.08
The value of x from the equation is 0.73. This value is already greater than 0.5. Thus, the isotope with greatest abundance is that which is 86 amu.
