<h3 /><h3>Answer:</h3>
Option A)
Magnesium chloride, MgCl2, is a binary compound with bonds with relatively high ionic character.
Answer:
16.9 mol
Explanation:
8Al + 3Fe₃O₄ ⟶ 4Al₂O₃ + 9Fe
You want to convert moles of Fe₃O₄ to moles of Al.
The molar ratio is 8 mol Al:3 mol Fe₃O₄. Calculate the moles of Al
Moles of Al = 6.34 × 8/3
Moles of Al = 6.34 × 2.667
Moles of Al = 16.9 mol Al
