Moles of Sulfuric acid needed to react completely : 3.2
<h3>Further explanation</h3>A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
Reaction (balanced)
<em>H₂SO₄ (aq) + 2 LiOH (aq) ⇒ Li₂SO₄ (aq) + 2 H₂O (l)</em>
moles of LiOH = 6.4
From equation, mol ratio of H₂SO₄ : LiOH = 1 : 2, so mol H₂SO₄ :
Answer:
8.25 moles
Explanation:
Given parameters:
Number of moles of Al produced = 11 moles
Unknown:
Number of moles of oxygen produced = ?
Solution:
To solve this problem, we need to understand the problem.
The decomposition of an aluminium oxide must has produced oxygen and aluminium,
2Al₂O₃ → 4Al + 3O₂
now since the known is the oxygen gas; we can find the unknown aluminium:
3 mole of O₂ was produced with 4 mole of Al
x mole of O₂ will be produced with 11 moles of Al
x = = 8.25 moles
