If an acid has a Ka of 4.3 × 10-⁷ and a base has a Kb of 5.6 × 10-⁴, then the true statement about the salt produced is that the salt would decrease the pH of the solution.
<h3>What is acid and base constant?</h3>
An acid dissociation constant, Kₐ, is a quantitative measure of the strength of an acid in solution while Kb indicates the high level of dissociation of a strong base.
According to this question, an acid has a Ka of 4.3 × 10-⁷ and a base has a Kb of 5.6 × 10-⁴. This shows that the strength of the base is higher than that of the acid.
Therefore, if an acid has a Ka of 4.3 × 10-⁷ and a base has a Kb of 5.6 × 10-⁴, then the true statement about the salt produced is that the salt would decrease the pH of the solution.

As many studies have shown that men have faster reflexes then woman, many woman can have better reflexes then men. It just depends on your genes and dna and all the things that make you be good at things.
the produce would be water and some form of salt
hope this helps
Answer:
Kp = 2.04
Explanation:
SCl₂(g) + 2 C₂H₄(g) ⇌ S(CH₂CH₂Cl)₂(g)
Kp = [S(CH₂CH₂Cl)₂] / [SCl₂][C₂H₄]²
[S(CH₂CH₂Cl)₂] = 0.350 M
[SCl₂] = [S(CH₂CH₂Cl)₂] = 0.350 M
[C₂H₄] = 2 x [S(CH₂CH₂Cl)₂] = 2 x 0.350 M = 0.700 M
Kp = 0.350 / 0.350 x 0.700²
Kp = 2.04
Answer:
3.1atm
Explanation:
Given parameters:
Volume of gas = 2L
Number of moles = 0.25mol
Temperature = 25°C = 25 + 273 = 298K
Unknown:
Pressure of the gas = ?
Solution:
To solve this problem, we use the ideal gas equation.
This is given as;
PV = nRT
P is the pressure
V is the volume
n is the number of moles
R is the gas constant = 0.082atmdm³mol⁻¹K⁻¹
T is the temperature
P =
Now insert the parameters and solve;
P = = 3.1atm
