Answer:
second answer
Explanation:
The melting point would occur more quickly but stay the same.
So it is answer 2
Answer:
[HAc] = 0.05M
[Ac⁻] = 0.20M
Explanation:
The Henderson-Hasselbalch formula for the acetic acid buffer is:
pH = pka + log₁₀ [Ac⁻] / [HAc]
Replacing:
5.36 = 4.76 + log₁₀ [Ac⁻] / [HAc]
3.981 = [Ac⁻] / [HAc] <em>(1)</em>
Also, as total concentration of buffer is 0.25M it is possible to write:
0.25M = [Ac⁻] + [HAc] <em>(2)</em>
Replacing (2) in (1)
3.981 = 0.25M - [HAc] / [HAc]
3.981 [HAc] = 0.25M - [HAc]
4.981 [HAc] = 0.25M
<em>[HAc] = 0.05M</em>
Replacing this value in (2):
0.25M = [Ac⁻] + 0.05M
<em>[Ac⁻] = 0.20M</em>
I hope it helps!
Answer:
I guess you just answered a lot of questions
Explanation:
Thanks for the points btw :)
Answer:
Heat is not something that can be contained since it is not a tangible thing. Heat is a process
Explanation:
A. Acids and bases don't react with each other. --> False. Acids and bases react in reactions called neutralization reactions, whose products are salt and water.
B. Acids mixed with bases neutralize each other. --> True. See above.
C. Acids mixed with bases make stronger bases. --> False. Acids and bases react to neutralize each other, so they would weaken each other, not result in a stronger base or a stronger acid.
D. Acids mixed with bases make stronger acids. --> False. See above.
<h3>
Answer:</h3>
B. Acids mixed with bases neutralize each other
