Question

Which colourless gas evolves when $N{H}_{4}Cl$ reacts with zinc in a dry cell battery ?

• A. $N{H}_3$
• B. $N_2$
• C. $H_2$
• D. $C{l}_2$

Answer 1

Answer: (C)

$H_2$ gas is evolved, when $Zn$ reacts with
$N{H}_{4}Cl$ in dry cell battery
$Zn+2N{H}_{4}Cl\to Zn(N{H}_3{)}_{2}C{l}_2+\underset{\text{colourless gas}}{H_2}\uparrow$
