Answer:

The ratio of atoms of potassium to atoms of oxygen is 2:1

Step-by-step explanation:

As the equation given is :


4K + O_2 -----> 2K_2O

The product formed is 2 moles of potassium oxide .

Amount of potassium atom in the potassium oxide is 2 atoms of potassium and amount of oxygen atom present here is 1 atom of oxygen .

But we have 2 moles of potassium oxide . So, the potassium and oxygen atoms will be multiplied by 2 .

Hence , we get 4 atoms of potassium and 2 atoms of oxygen .

Ratio of potassium to oxygen atoms is - 4:2

Therefore , 2:1
