Answer:
C2H5OH has a greater boiling point.
Explanation:
It is a bigger molecule than C2H6.
<span>Because
the question is asking moles of NH3, the compound, any subscripts are
irrelevant. It only wants to know how many moles of NH3 molecules, not
individual atoms.
Therefore, we can simply convert to moles. 1.5x10^23/6.022x10^23 = .249 moles of NH3.
(If it were to ask moles of Hydrogen, for example, you would multiply
the answer by 3, because there are 3 atoms of Hydrogen per one molecule
of NH3. But this only asks for moles of the entire compound).
hope you have a great day! :)

which means that the volume increased by 26.4 mL in order to compensate for the decrease in pressure.
Like I said, depends on what your initial volume was, but that's how you think of it.
Hope this helped!
D. a change in color of a substance
False, atoms can not be created that way
