Las concentraciones en el equilibrio para la reacción química presentada son:
![[A] = [B] = 1-x = 1-0.69 = 0.31 M\\[C] = [D] = x = 0.69 M](https://tex.z-dn.net/?f=%5BA%5D%20%3D%20%5BB%5D%20%3D%201-x%20%3D%201-0.69%20%3D%200.31%20M%5C%5C%5BC%5D%20%3D%20%5BD%5D%20%3D%20x%20%3D%200.69%20M)
Consideremos la siguiente reacción química genérica:
A + B ⇄ C + D
Para calcular las concentraciones en el equilibrio, debemos construir una Tabla ICE. Cada fila representa una instancia (Inicial, Cambio, Equilibrio) y la completamos con la concentración o cambio de concentración ("x" para concentraciones desconocidas). Como inicialmente no hay productos, la reacción se desplazará hacia la derecha para alcanzar el equilibrio.
A + B ⇄ C + D
I 1 1 0 0
C -x -x +x +x
E 1-x 1-x x x
La constante de equilibrio, Kc, es:
![Kc = 5 = \frac{[C][D]}{[A][B]} = \frac{x^{2} }{(1-x)^{2} } \\\sqrt{5} = x/1-x\\x = 0.69](https://tex.z-dn.net/?f=Kc%20%3D%205%20%3D%20%5Cfrac%7B%5BC%5D%5BD%5D%7D%7B%5BA%5D%5BB%5D%7D%20%3D%20%5Cfrac%7Bx%5E%7B2%7D%20%7D%7B%281-x%29%5E%7B2%7D%20%7D%20%5C%5C%5Csqrt%7B5%7D%20%3D%20x%2F1-x%5C%5Cx%20%3D%200.69)

It remains constant. (stays the same)
A. Each is found outside the nucleus
Answer:
Option e.
Explanation:
The option 'e' fact about Hydrogen bonds are correct, that is; ''form weak interactions but can provide structural stability when many are found in a single molecule''.
So, what is this Hydrogen bond?
Hydrogen bonds is a kind of strong dipole- dipole attractions. Hydrogen bonding occurs as a result of the bonding between hydrogen and strongly electronegative atoms for example oxygen, Fluorine and so on.
Since we now know what Hydrogen bond is, let us take a look at the options.
(a) for the first option, we can see from above meaning of Hydrogen bonds that Hydrogen bonds occur between Hydrogen and a strong Electronegative atom. So, this option is wrong.
(b). Option 'b' is also wrong Because Hydrogen bonds does not occur between hydrogen and oxygen atoms ONLY but also with other strong Electronegative atoms such as oxygen.
(c). Option 'c' is wrong because between a strong and not only between a weak electronegative atom and hydrogen.
(d). Option 'd' is also not correct.
(e). Option 'e' is correct. Hydrogen bonds contribute to the effect of boiling and melting point of substance, solubilty, dimerization, strength of bonds, shape of molecules and so on
Answer:
B
Explanation:
A is not the answer. Although the statement is accurate in regards to gases, it does not explain why liquids and gases can flow.
B is the answer. Solids are in fixed structures. When you apply heat or pressure, these structures are broken apart and allowed to move freely.
C is not the answer. This is inaccurate. Changing the phase of a substance does not change the size of the particle.
D is not the answer. The opposite of this statement is true. The attractive forces between particles in a solid allow the substance to hold its structure. When you apply heat or pressure, the attractive forces are overpowered and the structure is broken.
