Answer 1

Answer:

I believe the answer is B. Sodium carbonate

Answer 2

Answer : The correct option is, (B) Sodium carbonate

Explanation :

$Na_2CO_3$ It is an ionic compound because sodium element is a metal and carbonate ion is polyatomic ion. When the metal element combine with the polyatomic ion they form ionic compound.

$CO_3^{2-}$ = carbonate ion
