Answer:
A) = 4.7 × 10⁻⁴atm
Explanation:
Given that,
Kp = 1.5*10³ at 400°C
partial pressure pN2 = 0.10 atm
partial pressure pH2 = 0.15 atm
To determine:
Partial pressure pNH3 at equilibrium
The decomposition reaction is:-
2NH3(g) ↔N2(g) + 3H2(g)
Kp = [pH2]³[pN2]/[pNH3]²
pNH3 =√ [(pH2)³(pN2)/Kp]
pNH3 = √(0.15)³(0.10)/1.5*10³ = 4.74*10⁻⁴ atm
![K_p = \frac{[pH_2] ^3[pN_2]}{[pNH_3]^2} \\pNH_3 = \sqrt{\frac{(pH_2)^3(pN_2)}{pNH_3} } \\pNH_3 = \sqrt{\frac{(0.15)^3(0.10)}{1.5 \times 10^3} } \\=4.74 \times 10^-^4atm](https://tex.z-dn.net/?f=K_p%20%3D%20%5Cfrac%7B%5BpH_2%5D%20%5E3%5BpN_2%5D%7D%7B%5BpNH_3%5D%5E2%7D%20%5C%5CpNH_3%20%3D%20%5Csqrt%7B%5Cfrac%7B%28pH_2%29%5E3%28pN_2%29%7D%7BpNH_3%7D%20%7D%20%5C%5CpNH_3%20%3D%20%5Csqrt%7B%5Cfrac%7B%280.15%29%5E3%280.10%29%7D%7B1.5%20%5Ctimes%2010%5E3%7D%20%7D%20%5C%5C%3D4.74%20%5Ctimes%2010%5E-%5E4atm)

A force of attraction that
holds atom together
When atoms react they form a
chemical bond which is defined as a force of attraction that holds atom
together. A force of attraction is defined as a kind of force that draws two or
more objects together regardless of distance. There are two major categories of
forces of attraction, one is intramolecular and intermolecular. Intramolecular forces
is the presence of forces in atoms internally. While intermolecular is the
force by which the force that is existent in two or more elements.
The van 't Hoff factor is the ratio between the actual concentration of particles produced when the substance is dissolved and the concentration of a substance as calculated from its mass. For most non-electrolytes dissolved in water, the van 't Hoff factor is essentially 1.
<h3>What is the value of
van 't Hoff factor?</h3>
For most non-electrolytes dissolved in water, the Van 't Hoff factor is essentially $ 1 $ . For most ionic compounds dissolved in water, the Van 't Hoff factor is equal to the number of discrete ions in a formula unit of the substance.
Which has highest Van t Hoff factor?
The Van't Hoff factor will be highest for
A. Sodium chloride.
B. Magnesium chloride.
C. Sodium phosphate.
D. Urea.

Answer:
La tabla periódica de moseley fue una manera de dar solución a esta problemática, ya que nos permite tener a la mano todos los elementos que se han descubierto hasta la actualidad y sus propiedades químicas más resaltantes.
A continuación se Describe una linea del tiempo de la creación de la tabla periodica:
1820 - se crean las tríadas de Dobereiner.
1863 - se crea el cilindro de chancourtois.
1864 - se crean las octavas de newlands.
1869 - se crea el primer prototipo de la tabla periódica.
1914 - se fórmula la ley periódica moderna por Moseley.
