Answer:</h3>
Partial pressure of He(P(He) = 1.5 atm.
Partial pressure of Ne(P(Ne) = 1 atm.
Partial pressure of Ar(P(Ar) = 0.5 atm.
<h3>
Explanation:</h3>
According to Dalton law of partial pressure the sum of partial pressures of individual gases in a gaseous mixture is equivalent to the total pressure.
The partial pressure of a gas in a gaseous mixture is given by the product of the mole fraction and the total pressure.
Our gaseous mixture contains He, Ne, and Ar and the total pressure is 3 atm.
Since we are given the ratios of the gases in the mixture, we can calculate the partial pressure of each gas.
P(He) = 3/6 × 3 atm.
= 1.5 atm.
P(Ne) = 2/6 × 3 atm.
= 1 atm
P(Ar) = 1/6 × 3 atm.
= 0.5 atm
Therefore, the partial pressures of gases He, Ne and Ar are 1.5 atm, 1 atm, and 0.5 atm respectively.

Answer:
the equilibrium concentration of HF is 2.85 M
Option a) 2.85 M is the correct answer.
Explanation:
Given the data in the question;
H₂ + F₂ ⇄ 2HF
I 1.69 M 1.69 M 0
C -x -x +2x
E 1.69-x 1.69-x +2x
given that Kc = 115
Kc = [ HF ]² / [H₂][F₂]
we substitute
115 = [ 2x ]² / [ 1.69-x ][ 1.69-x ]
lets find the square root of both sides
10.7238 = 2x / [ 1.69-x ]
10.7238[ 1.69-x ] = 2x
18.123222 - 10.7238x = 2x
2x + 10.7238x = 18.123222
12.7238x = 18.123222
x = 18.123222 / 12.7238
x = 1.424356
Hence, equilibrium concentration of HF = 2x
that is;
HF = 2 × 1.424356
HF = 2.8487 ≈ 2.85 M
Therefore, the equilibrium concentration of HF is 2.85 M
Option a) 2.85 M is the correct answer.
