The total pressure of the gases above an equilibrium mixture is 0.1343 atm

Explanation:-

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as K_p

For the given chemical reaction:

$H_2S(g)+I_2(g)\rightarrow S(g)+2HI(g)$

The expression for K_p is written as:

$K_p=\frac{(p_{HI})^2}{(p_{H_2S})^1}$

$K_p=1.33\times 10^{-5}$

$1.33\times 10^{-5}=\frac{p_{HI}^2}{p_{H_2S}^1}$

$1.33\times 10^{-5}=\frac{(0.010\times p_{H_2S})^2}{p_{H_2S}^1}$

$p_{H_2S}=0.133$

$p_{HI}=0.010\times 0.133=0.0013$

Total pressure at equilibrium = $p_{H_2S}+p_{HI}$ = 0.133+0.0013 = 0.1343 atm

mechanics (greek is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.

Answer from: Quest

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

$^{m}_{4}x$ and $^{m}_4y$

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

$^{m}_{5}x^{-}$

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be $^{9}_{5}be^{-}$ and $^{9}_{4}be$ .

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
