Open in App

Solution

$N a O C l Δ \to N a C l O_{3} + N a C l$
There are 3 oxygen atoms in $N a C l O_{3}$ so, there should be 3 oxygen atoms present in the reactant $N a O C l$ .
So, the reaction would be $3 N a C l O \to N a C l O_{3} + 2 N a C l$ .
Hence, 3 moles of given compound is decomposed.
