Answer:
P = 0.444 atm
Explanation:
The reaction of decomposition of H₂S is:
H₂S(g) ⇄ H₂(g) + S(g)
<em>Initial</em> 0.245 0 0
<em>Equilibrium </em>0.245-x x x
The equilibrium constant (Kp) of the above reaction is the following:
(1)
Knowing that initally, only H₂S is present at P = 0.245, the Kp of equation (1) at equilibrium is:
Using the quadratic formula we get x₁ = 0.199 and x₂ = -1.058.
Taking only the possitive number we have that:
Therefore, the total pressure in the container at equilibrium is:

The correct answer is making observations in his experiment.
In his cathode ray tube experiment J. J. Thomson proved that the cathode rays are indeed negatively charged particles. He then went on to calculate charge-to-mass ratio of the electron. J. J. Thomson’s pioneering work lest to the theory that the atomic structure is made up of charged particles.
The electron distribution in the Si atom : D. 2,8,4
<h3>Further explanation</h3>
The maximum number of electrons that can be filled in the nth electron shell is 2n²(n=shell)
- K shell (n = 1) maximum 2 x 1² = 2 electrons
- L shell (n = 2) maximum 2 x 2² = 8 electrons
- M shell (n = 3) maximum 2 x 3² = 18 electrons
- N shell (n = 4) maximum 2 x 4² = 32 electrons
Electron configuration of Si : 1s² 2s2²2p6⁶3s²3p² = 14 electron
The electron distribution :
K shell = 2
L shell = 8
M shell = 4
