Answer :
Answer:
Formula of sodium carbonate is [tex]Na_{2}CO_{3}[/tex].
Explanation:
Sodium carbonate is an ionic compound consists of [tex]Na^{+}[/tex] and [tex]CO_{3}^{2-}[/tex] ions.
In a formula unit of sodium carbonate, there should be two [tex]Na^{+}[/tex] ions and one [tex]CO_{3}^{2-}[/tex] ion to maintain charge neutrality.
In general, formula of an ionic compound consists of [tex]A^{x+}[/tex] and [tex]B^{y-}[/tex] ions is written as : [tex]A_{y}B_{x}[/tex] ([tex]x\neq y[/tex]) and AB ([tex]x= y[/tex])
If x or y is equal to 1 then it is not written explicitly in formula.
So, formula of sodium carbonate = [tex]Na_{2}CO_{3}[/tex]
