Explanation:

The problem involves identifying elements in Sodium Carbonate ($\ce{Na2CO3}$). Sodium Carbonate has the formula $\ce{Na2CO3}$, so the elements present are Sodium (Na), Carbon (C), and Oxygen (O). We need to match these elements from the left list (Br, Li, S, Si, H, Mg, P, Na, C, O) to the right (dashed boxes). So Na, C, O should be connected as they are in $\ce{Na2CO3}$.

Answer:

For $\ce{Na2CO3}$, the elements are Sodium (Na), Carbon (C), and Oxygen (O). So connect Na, C, O to their respective dashed boxes (the ones they are linked to, as they are the constituent elements of Sodium Carbonate).
