2Al₂O₃ → 4Al + 3O₂

the mole ratio is 4:3
for every 4 Al, there must be 3 O₂ in order to make 2Al₂O₃

hope this helped at all

The study of chemicals is called chemistry.

The correct answer to the question is 4:3

What is the mole?

  • The mole is the base unit of the amount of substance in the International System of Units. It is defined as exactly [tex]6.02214076*10^{23[/tex] elementary entities,

The reaction used in the question is as follows:-

[tex]2Al_2O_3--->4Al + 3O_2[/tex]

The ratio in which the aluminum and oxygen react is 4:3 . so that every 4 Al, there must be 3 O₂ in order to make [tex]2Al_2O_3[/tex] .

hence, the correct answer is 4:3
