Group of answer choices

tin

sodium

Answer 1

Sodium.

Reason: In a single‑replacement reaction the more reactive metal will displace the less reactive metal from its compound. Sodium (an alkali metal) is much more reactive than tin, so Na will replace Sn. Example:
2 Na(s) + SnCl2(aq) → Sn(s) + 2 NaCl(aq).
