The product that you obtain if you evaporate the water from the NaoH layer prior to acidifying the layer is salt of <u> para - tery-butyphenol</u>
<u><em>Explanation</em></u>
- Para-tery-butyphenol can be isolate after extracting it into NaOH solution through carrying out
- heating and then cooling,
- then 3M of HCl is added to acidify.
- Then ice bath is done if needed
- finally the precipitate is filtered.
- Para tery butyphenol can be used for production of alkylphenolic.
the force between the electron and the proton.
a) Use F = k * q1 * q2 / d²
where k = 8.99e9 N·m²/C²
and q1 = -1.602e-19 C (electron)
and q2 = 1.602e-19 C (proton)
and d = distance between point charges = 0.53e-10 m
The negative result indicates "attraction".
the radial acceleration of the electron.
b) Here, just use F = ma
where F was found above, and
m = mass of electron = 9.11e-31kg, if memory serves
a = radial acceleration
the speed of the electron.
c) Now use a = v² / r
where a was found above
and r was given
<span> the period of the circular motion.</span>
d) period T = 2π / ω = 2πr / v
where v was found above
and r was given
Answer:
I would say water
Explanation:
The molecules that make up ice actually have more space between them than the molecules in liquid water do. Steam can flow around really easily making there be even more space for them.
sorry if this is wrong. I just did research and this is what I got.
Water that contains large amounts of disolved salts
Answer:
All life on Earth descended from a common ancestor
