How many moles of aluminum are needed to react completely with 1.2 mol of feo
Lelu [443]

Answer:

  • <u><em>0.80 mol Al</em></u>

Explanation:

<u>1) Word reaction:</u>

  • Aluminum + ferrous oxide → aluminum oxide + iron

This is a single replacement reaction, in which aluminum, a more acitve metal than iron, replaces the iron in the ferrous oxide to form aluminum oxide and iron.

<u>2) Skeleton chemical equation:</u>

  • Al + FeO → Al₂O₃ + Fe

<u>3) Balanced chemical equation:</u>

Add the coeffcients to comply with the law of conservation of mass:

  • 2Al + 3FeO → Al₂O₃ + 3Fe

<u>4) Mole ratio of Al and FeO:</u>

  • 2 mol Al : 3 mol FeO

<u>5) Set a proportion with the unkown and solve:</u>

  • x / 1.2 mol FeO = 2 mol Al / 3 mol FeO

  • x = 1.2 mol FeO × 2 mol Al / 3 mol FeO =<u> </u><u>0.80 mol Al ← answer</u>
