Answer 2

4Al(s) + 3O2(g) → 2Al2O3(s)

Step-by-step explanation:

The balanced equation for the formation of aluminum oxide is:

4Al(s) + 3O2(g) → 2Al2O3(s)

From this equation, we can derive several mole ratios:

• For every 4 moles of aluminum, 2 moles of aluminum oxide are formed.
• For every 3 moles of oxygen, 2 moles of aluminum oxide are formed.
• For every 2 moles of aluminum oxide formed, 4 moles of aluminum were used.
• For every 2 moles of aluminum oxide formed, 3 moles of oxygen were used.
• The ratio of aluminum to oxygen used in the reaction is 4:3.
• The ratio of aluminum oxide to oxygen used in the reaction is 2:3.
