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](https://img.qammunity.org/2022/formulas/chemistry/high-school/b0v7i16fofrz0cnuu0mugsdrujea9ayvkz.png)
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
