Respuesta :
For every O ion, two Na ions are needed to balance charges. Which ratio represents the relationship between Na and O?
2 Na:1 O
Answer:
Ratio represents the relationship between Na and O is 2:1.
Explanation:
Given that for every oxygen ion two sodium ions are needed to balance charge.
1 oxygen ion requires 2 sodium atoms
[tex]O^{2-}+2Na^+\rightarrow Na_2O[/tex]
The ratio of oxygen ion to sodium ions is:[tex]\frac{1}{2}[/tex]
So, on reversing the ratio we will get the ratio of sodium ions to oxygen ions:
[tex]\frac{Na^+}{O^{2-}}=\frac{2}{1}[/tex]
