Balanced reaction is 4 Zn + NaNO 3+7 NaOH arrow 4 Na 2 ZnO 2+ underset[A][ NH 3]+2 H 2 O The sum of stoichiometric coefficients of Zn and [ A ]=4+1=5

Q. In the reaction:
$Z n + N a N O_{3} + N a O H \to N a_{2} Z n O_{2} + A + H_{2} O$
The sum of stoichiometric coefficients of $Z n$ and $A$ in the balanced reaction with simplest integer coefficient is

Balanced reaction is
$4 Z n + N a N O_{3} + 7 N a O H \to 4 N a_{2} Z n O_{2} + [A] [N H_{3}] + 2 H_{2} O$
The sum of stoichiometric coefficients of $Z n$ and $[A] = 4 + 1 = 5$
