Answer:
The total pressure in the container at equilibrium is 0.37065 atm
Explanation:
<u>Step 1: </u>Data given
Kp for the decomposition of H2S is 0.795
Only H2S is present at a pressure of 0.203 atm
<u>Step 2:</u> The balanced equation
H2S (g) → H2(g) + S(g)
<u>Step 3: </u>Calculate partial pressure of H2 and S
Initially, there is no H2 and S, they have no pressure
There will react X
The pressure at the equilibrium we have:
H2: X
S: X
H2S: 0.203 - X
Kp = (pH2)(pS)/(pH2S)
0.795 = (x)(x)/(0.203 - X)
X = 0.16765
<u>Step 4:</u> Calculate total pressure at equilibrium:
Total pressure = the partial pressure of H2 + partial pressure of S + partial pressure of H2S
P = X + X + (0.203 - X)
P = 0.16765 + 0.16765 + (0.203 - 0.16765)
P = 0.37065 atm
The total pressure in the container at equilibrium is 0.37065 atm
Answer is: 2) 14/7 N + 4/2 He --> 17/8 O + 1/1 H.
Transmutation is a process that involves a change in the nucleus of an atom. It can be natural or artificial.
This example is the first artificial nuclear transmutation described by Rutherford in 1919.
Artificial transmutation can be expressed by nuclear reaction:
Target Nuclide + Bombardment Particle → New Nuclide + Ejected Particle.
