The answer is forensic sociologist
I just took the exam and it’s rights
Answer:
In the first part of Lesson 1, it was mentioned that sound is a mechanical wave that is created by a vibrating object. The vibrations of the object set particles in the surrounding medium in vibrational motion, thus transporting energy through the medium.
<span>Well # # Drops of Iron Sulfate # Drops of Sodium Hydroxide

<span>that's for B, because it says "Iron Sulfate".
which is this equation:
FeSO4 (aq) + 2NaOH (aq) Fe(OH)2 (s) + Na2SO4 (aq)
</span>
<span>FeSO4 (aq) + 2NaOH (aq) Fe(OH)2 (s) + Na2SO4 (aq)
ratio of FeSO4:NaOH is 1:2,
so you need to moles of NaOH for every mole of FeSO4.

<span>A1-A6 had precipitate, though less ppt every time.
This corresponds to the decrease in the number of NaOH drops
At A2 10/1:40/2 the stoichiometric ratio is equal, so you should've seen the post ppt present. But looking at the picture it doesn't look right. I think you might've labelled them wrong, or there is an error somewhere. This fits micro-plate A better.</span><span>

D. A little rainfall and high temperatures
