Question

3. __Al + __O2 --> __Al2O3You have 8 moles of Al. How many moles of Al2O3 will be produced?

Answer 1

4Al + 3O2 ------> 2Al₂O₃

4 moles of Al₂O₃ will be produced

Step-by-step explanation

Given:

Moles of A = 8 moles

The given unbalanced equation is: __Al + __O2 --> __Al2O3

Solution:

The balanced equation for the reaction is:

4Al + 3O2 ------> 2Al₂O₃

From the balanced equation, 4 moles of Al produced 2 moles Al₂O₃

Therefore, 8 moles of Al will produce

`\frac{8\text{ }moles\text{ }Al}{4\text{ }moles\text{ }Al}*2\text{ }moles\text{ }Al_2O_3=4\text{ }moles\text{ }Al_2O_3`

4 moles of Al₂O₃ will be produced.
