Final Answer : Hydrogen gas will. be released in all cases except NaCl.
Steps and Understanding:
1) Zn reacts with Sulphuric acid, to obtain
Zinc Sulphate and Hydrogen Sulphate.
Zn + H2SO4 ------>>ZnSO4 + H2 gas
2) Zn + HCl ------->>ZnCl2 + H2
Zinc reacts with Hydrogen Chloride forming
Zinc Chloride and Hydrogen Gas.
3) Zn reacts with dilute Nitric Acid to obtain
Zinc Nitrate and Hydrogen gas.
Zn + HNO3. -----> Zn(NO3)2. + H2
4)Zinc reacts with excess of Sodium Hydroxide to obtain
Sodium Zincate.
Zn + NaOH ------->> Na2ZnO2. + H2
5) Since, reactivity of Sodium is higher than Zinc, so Zinc can't displace Sodium.
So, No Reaction.
