Respuesta :
Answer:
2:1
Explanation:
The given equation is :
[tex]4K+O_2\rightarrow 2K_2O[/tex]
K is potassium
O is oxygen
This equation shows a combustion reaction that shows that when potassium reacts with oxygen it form potassium oxide. When 4 moles of potassium reacts with two moles of oxygen it form two moles of potassium oxide.
Number of atoms of potassium is 4
Number of moles of oxygen is 2
Ratio is 4:2 or 2:1
The equation below is for potassium oxide.
4K + O2 2K2O
What is the ratio of atoms of potassium to atoms of oxygen?
1:2
2:1
4:1
1:4
Answer:B
