Answer 1

Answer:

zinc produces hydrogen gas upon reaction with hydrochloric acid , the reaction should be,

zn+ 2hcl gives zncl2 +h2

Answer 2

Answer:

zinc only

Explanation:

Alright.... let's take the first one Ammonia ( NH3 )

NH3 +HCl → NH4+  +  Cl-  →  NH4Cl

so no H2 gas

Next Zn,

Zn +2 HCl →  ZnCl2 + H2

so H2 gas is produced

And the last...

NaHCO3 + HCl → NaCl + H2O +CO2

Again no H2 gas.

So the answer for your question will be only ZINC.
