Answer : The number of moles of oxygen produced are, 8.25 mole

Explanation : Given,

Moles of Al = 11 mole

The balanced chemical reaction will be,

[tex]2Al_2O_3\rightarrow 4Al+3O_2[/tex]

From the balanced chemical reaction we conclude that,

If 4 moles of Al are produced then 3 mole of oxygen are also produced

So, 11 moles of Al are produced then [tex]\frac{3}{4}\times 11=8.25mole[/tex] of oxygen are also produced

Therefore, the number of moles of oxygen produced are, 8.25 mole

Answer: The moles of oxygen produced will be 8.25 moles.

Explanation:

We are given:

Moles of aluminium produced = 11.0 mol

The chemical equation for the decomposition of aluminium oxide follows:

[tex]2Al_2O_3\rightarrow 4Al+3O_2[/tex]

By Stoichiometry of the reaction:

When 4 moles of aluminium is produced, 3 moles of oxygen gas is also produced.

So, when 11.0 moles of aluminium is produced, [tex]\frac{3}{4}\times 11.0=8.25mol[/tex] of oxygen is also produced.

Hence, the moles of oxygen produced will be 8.25 moles.
