Question

which model correctly represents dissolved nabr?

Explanation:

text{Br}^- \) has white (H) around it? Wait the top-right’s \( \text{Br}^- \) (green) has red (O) and white (H) with H facing \( \text{Br}^- \)? Let me look at the image again.

Looking at the image:

• Top-left: \( \text{Br}^- \) (green) has water molecules with O (red) near \( \text{Br}^- \) (H away) → wrong. \( \text{Na}^+ \) (purple) has water molecules with H (white) near \( \text{Na}^+ \) (O away) → wrong.
• Top-right: \( \text{Br}^- \) (green) has water molecules with H (white) near \( \text{Br}^- \) (O away) → correct. \( \text{Na}^+ \) (purple) has water molecules with O (red) near \( \text{Na}^+ \) (H away) → correct.
• Bottom-left: \( \text{Na}^+ \) has one water with H near (wrong), \( \text{Br}^- \) has one water with O near (wrong).
• Bottom-right: \( \text{Na}^+ \) has water with O near (correct), \( \text{Br}^- \) has water with O near (wrong, should have H near).

Wait, but the bottom-right’s \( \text{Br}^- \) has white (H) around it? Wait no, the bottom-right’s \( \text{Br}^- \) has red (O) and white (H) with H facing \( \text{Br}^- \)? Wait the bottom-right’s \( \text{Br}^- \) is green, and the water around it has white (H) facing \( \
