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: (D)

$H_2$ gas is evolved. When Zn reacts with $N{H}_{4}Cl$ in dry cell battery. $Zn+2N{H}_{4}Cl\to Zn{(N{H}_3)}_{2}C{l}_2+\underset{\begin{array}{c}colourless\\ gas\end{array}}{H_2\uparrow }$
