Consider the following reactions (unbalanced)
$Z n + H o t c o n c . H_{2} S O_{4} \to G + R + X$
$Z n + c o n c . N a O H \to T + Q$
$G + H_{2} S + {N H}_{4} O H \to Z (a p r e c i p i t a t e) + X + Y$
Choose the correct option(s).

Options:(select one or more)

Answer:

B, C, D

Solution:

$Zn + \underset{(Hot&Conc.)}{H_{2} {SO}_{4}} \to \underset{(N)}{{ZnSO}_{4}} + \underset{®}{{SO}_{2}} + \underset{(X)}{H_{2} O}$
$Zn + \underset{(Conc.)}{2NaOH} \to \underset{(T)}{{NaZnO}_{2}} + \underset{(Q)}{H_{2}}$
${ZnSO}_{4} + H_{2} S + {NH}_{4} OH \to \underset{(S)}{ZnS} + \underset{(X)}{H_{2} O} + \underset{(Y)}{{({NH}_{4})}_{2} {SO}_{4}}$
