Depression is hard and no one knows how to treat it and we don't want to spread negative feelings and want to be left along thinking that it will make everything better in all reality it doesn't
You're starting with
(12.0 mL) (0.550 M) = (0.0120 L) (0.550 M) = 0.00660 mol
of FeCl₃.
For every mole of FeCl₃ in the balanced reaction, you need 3 moles of NH₄OH, so you need a minimum 0.0198 mol NH₄OH per mole FeCl₃.
Then the requisite volume of NH₄OH solution needed is <em>V</em> such that
(0.0198 mol) / <em>V</em> = 0.200 M
Solve for <em>V</em> to get
<em>V</em> = (0.0198 mol) / (0.200 M) = 0.0990 L = 99 mL
My best guess would be prolific, since it means to show in large quantities.
D is the correct answer as there are reduced punishments for juvenile offenders and mentally ill people as it is believed that they are truly not thinking their actions through properly and are not capable of making the proper decisions.
