Hopes this helps:
Answer: So the pH of the solution is 4.
Answer:
k = 2,04x10⁻⁵
Explanation:
The equilibrium of acetic acid (CH₃COOH) in water is:
CH₃COOH ⇄ CH₃COO⁻ + H⁺.
And the equilibrium constant is defined as:
k = [CH₃COO⁻] [H⁺] / [CH₃COOH] <em>(1)</em>
The equiibrium concentration of each specie if the solution of acetic acid is 0,05M is:
[CH₃COOH] = 0,05M - x
[CH₃COO⁻] = x
[H⁺] = x
<em>-Where x is the degree of reaction progress-</em>
As the pH is 3, [H⁺] = 1x10⁻³M. That means x = 1x10⁻³M
Replacing in (1):
k = (1x10⁻³)² / 0,05 - 1x10⁻³
k = 1x10⁻⁶ / 0,049
<em>k = 2,04x10⁻⁵</em>

Answer:
Third figure shows the best relationship.
(c) is correct option.
Explanation:
Given that,
The diagram best represents the relationship masses of subatomic particles.
We know that,
The mass of proton and neutron are same.
The mass of electron is less than mass of the proton and neutron.
We need to find the best represents the relationship masses of subatomic particles
According to figure,
Third figure shows the best represents the relationship masses of subatomic particles.
Hence, Third figure shows the best relationship.
(c) is correct option.
