C). how many mole of a1,0, (aluminum oxide) would be produced from reacting 8 mole of aluminum?

4 mol of Al₂O₃ are produced from 8 mole of Al

Explanation:

The reaction:

4 Al + 3O₂  →  2Al₂O₃

Ratio is 4:2

So, If we have 8 mol of Al, we will produce 4 mol of Al₂O₃

There will be 4.0 moles of Aluminium oxide produced.

Explanation:

Step 1: Data given

Number of moles of Aluminium (Al) = 8.0 moles

Step 2: The balanced equation

4Al + 3O2 → 2Al2O3

Step 3: Calculate moles of Aluminium oxide (Al2O3)

For 4 moles of Aluminium consumed, we need 3 moles of O2 to produce 2 moles of Al2O3

For 8.0 moles of Al consumed, we'll have 8.0 / 2 = 4.0 moles of Al2O3

There will be 4.0 moles of Aluminium oxide produced.
