Explanation: Amphoteric = reacts with both acids & bases.

Q13. Which gas is released when metals react with acids?

A. Oxygen
B. Hydrogen
C. Nitrogen
D. Carbon dioxide

✅ Correct Answer: B. Hydrogen

Q14. What happens when sodium reacts with water?

A. Hydrogen gas evolves, solution is acidic
B. Hydrogen gas evolves, solution is basic
C. Oxygen gas evolves, solution is neutral
D. No reaction

✅ Correct Answer: B. Hydrogen gas evolves, solution is basic

Explanation: Na + H₂O → NaOH + H₂.

Q15. Which metal does NOT react with water at all?

A. Magnesium
B. Zinc
C. Iron
D. Copper

✅ Correct Answer: D. Copper

Q17. Which metal is stored under kerosene?

A. Zinc
B. Iron
C. Sodium
D. Aluminium

✅ Correct Answer: C. Sodium

Explanation: Sodium reacts vigorously with air & water, hence stored in kerosene.
