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

According to the big bang theory, what happens if you reverse the galaxy motion and go back in time?.
fomenos

The reverse of the Big Bang Theory simply means the scenario where the expansion of the universe reverses. Known as well as the "Big Crunch". This event supposedly would lead to the collapse of the universe.

When it falls under this, the cosmic scale then reaches 0. Subsequently, everything would become condensed into a very dense point.
