Hey there!

To balance this equation, you will need:

6Al + 3O₂ = 3Al₂O₃

I hope this helps!

Answer: The sequence of coefficients is 2 , 3 and 2 in [tex]2Al+3O_2\rightarrow 2Al_2O_3[/tex]

Explanation:

According to law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products must be same as the mass of reactants.

For this, the number of atoms of each element must be same on both sides of the equation. Thus a balanced chemical equation is written.

[tex]2Al+3O_2\rightarrow 2Al_2O_3[/tex]
