<li>NaNO3, Na2S, Na3PO4, Na2CO3, NaOH.
The answer is NaNO3; please give an explanation why, and explanations for the other ones.</li>
</ol>

<p>…AlCl3(aq)+…NH3(aq)+…H20 —></p>

<p>Which of the following is one of the products obtained from the reaction above?

  1. AlN, AlH3, Al, Al(NO3)3, Al(OH)3. The answer is Al(OH)3. Why?</p>

<p>I haven’t taken a real chemistry class so I have trouble with reactions.
