Answer:
If u use math why It will give u the answer like 3x3=9

Answer:
Partial pressure of ammonia is 0,28.
Explanation:
For the reaction:
NH₄HS(s) ⇄ NH₃(g) + H₂S(g)
kp = 0,080 is defined as:
0,080 = P[NH₃] P[H₂S] <em>(1)</em>
Where P[NH₃] is partial pressure of NH₃
Asuming amount of NH₄HS is 1, equilibrium concentration for each compound is:
[NH₄HS] = 1 - x
P [NH₃] = x
P [H₂S] = x
Replacing in (1):
0,080 = X×X
0,080 = X²
X = 0,28 = P[NH₃]
I hope it helps
My Choice will be the sample C with a coefficient of absorption 62 % and the reason is that the percentage of the energy in an incident wave that remains in a reflected wave from this material is the smallest. Because this sample has the highest percentage of the coefficient of absorption than the other samples, As the sound Absorption coefficient is a part of the sound energy that absorbed by a material.And Its value varies with the angles of incident and frequency. So sample C is the best to be used as a soundproof room.
There is one missing point in the question.
The formula to find an increase in boiling Temperature is :
ΔT = kb x M
ΔT = is the increase in boiling Temperature
Kb = Boiling point constant of the Solvent
M = Molarity
You did not provide the Kb. If you have it, you just have to insert it to the formula to find the ΔT.
And assuming that the other solution is water, you just have to add it up with 100 Celcius
