We have that for the Question it can be said that the NaOH combines with CH_3COOH to produce CH_3COONa (Salt)
From the question we are told
how should the ph of a 0.1 m solution of <em>nac2h3o2</em> compare with that of a 0.1 m <u>solution </u>of kc2h3o2?
Generally
with the ph of a 0.1 m solution of <em>nac2h3o2</em> compared with that of a 0.1 m <u>solution </u>of kc2h3o2 ,we see that the salt produce is a weak acid and strong akali salt
We see that the salt produced in water gives a base from the derived weak acid
The salt produce is CH_3COONa
Therefore
the NaOH combines with CH_3COOH to produce CH_3COONa (Salt)

Answer:
They all end up in the oceon
Explanation:
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>

I hope it helps!
The temperature if the volume were changed to 225 ml at a pressure of 785 torrs is 129K.
Pressure is constant.
so
V1 / T1 = v2 / T2
so
T2 = V2 T1 / V1
T2 = 225 x 242 / 422
T2 = 129K
What is temperature?
Temperature is a measure of hotness or coldness expressed on several scales, including Fahrenheit and Celsius. Temperature indicates the direction in which thermal energy spontaneously flows - ie, from a hotter body (one at a higher temperature) to a colder body (another at a lower temperature).
The Fahrenheit temperature scale (°F) is used in the United States and some other English-speaking countries. The Celsius temperature scale (°C) is standard in almost all countries that have adopted the metric system and is widely used in science. The Kelvin (K) scale, the absolute temperature scale is recognized as the international standard for scientific temperature measurement.
