# How many moles of oxygen are produced if 11.0 mol of al are produced?

How many moles of oxygen are produced if 11.0 mol of al are produced?

11.0 mol AI ( 1 mol O2/ 4 mol AI) = 2. 75 mol O2
2 Al₂O₃ = 4 Al + 3 O₂

4 moles Al > 3 moles O₂
11.0 moles Al > ?

O₂ = 11.0 * 3 / 4

= 8.25 moles of O₂

hope this helps!

2 Al₂O₃ = 4 Al + 3 O₂

4 moles Al > 3 moles O₂
11.0 moles Al > ?

O₂ = 11.0 * 3 / 4

= 8.25 moles of O₂

hope this helps you and have a great day!

8.25 moles of oxygen are produced.

Explanation: The reaction follows: By Stoichiometry,

As, 4 moles of Aluminium is produced by 2 moles of aluminium oxide

11 moles of aluminium will be produced by = Now, 2 moles of aluminium oxide produces 3 moles of oxygen, so

5.5 moles of Aluminium oxide will produce = Hence, 8.25 moles of oxygen will be produced.

a  8.25 moles of O₂

Explanation: on edge

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: 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, of oxygen is also produced.

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

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

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, 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 of oxygen are also produced

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