Dalton's law of partial pressures states that the total pressure of a gas mixture is equal to the sum of the partial pressures of its individual gases.
<h3>What is partial pressure?</h3>
Partial pressure is defined as the pressure exerted by individual gas constituents that makes up a mixture of gases.
According to Dalton's law of partial pressures which states that the total pressure by a mixture of gases is equal to the sum of the partial pressures of each of the constituent gases.
This can be represented mathematically by the following:
P = P1 + P2
Where P = total pressure
P1 = partial pressure of gas 1
P2 = partial pressure of gas 2.

First, we need to calculate Ka in order to determine the pKa.
The formula for Ka = x^2/ initial concentration
initial concentration= 0.0147 M
we need to find x, and we can use the pH to find it because x is the [H+] concentration.
[H+]= 10^-pH----> [H+]= 10^-2.46= 0.00347
Ka= x^2/ initial---------> (0.00347)^2/ 0.0147= 8.18 x 10^-4
now that we have Ka, we can determine pKa using the following formula--> pKa= -log Ka
pKa= -log (8.18 x 10^-4)= 3.087
Answer: Option (4) is the correct answer.
Explanation:
It is known that equilibrium constant is represented as follows for any general reaction.
K =
As equilibrium constant is directly proportional to the concentration of products so more is the value of equilibrium constant more will be the number of products formed.
As a result, more is the time taken by the reaction to reach towards equilibrium. Whereas smaller is the value of equilibrium constant more rapidly it will reach towards the equilibrium.
Thus, we can conclude that cases where K is a very small number will require the LEAST time to arrive at equilibrium.

Answer:
The concentration of the Cu2 in the 100.0 ml volumetric flask is 0.0592 M
Explanation:
In the first dilution, Cu2 was diluted ten times (25 / 250 = 1/10). Then, this dilution was diluted again, but now five times (20 / 100 = 1/5). In total, the solution was diluted 50 times (1/10 * 1/5 = 1/50). The final concentration will be 2.96 M / 50 = 0.0592 M
