How many moles of aluminum oxide can be made if 4.0 moles Al completely react?

Answer 1

The balanced chemical equation for the reaction between aluminum (Al) and oxygen (O₂) to form aluminum oxide (Al₂O₃) is:

[ 4 \text{ Al} + 3 \text{ O}_2 \rightarrow 2 \text{ Al}_2\text{O}_3 ]

According to the balanced equation, 4 moles of aluminum (Al) produce 2 moles of aluminum oxide (Al₂O₃). Therefore, if 4.0 moles of aluminum completely react, it will produce ( \frac{2}{4} \times 4.0 ) moles of aluminum oxide. Calculate that to find the answer.

Answer 2

I assume this equation.


4Al + 3O2 --> 2Al2O3

4.0 moles Al (2 moles Al2O3/4 moles Al)

= 2.0 moles aluminum oxide produced
