Q. In the reaction, $H_{2} O_{2} + N a_{2} C O_{3} \to N a_{2} O_{2} + C O_{2} + H_{2} O$ the substance undergoing oxidation is

$H_{2} O_{2}$

none

$N a_{2} C O_{3}$

$N a_{2} O_{2}$

$H_{2} +1 O_{2} -1 + N a_{2} C +4 O_{3} -2 \to N a_{2} O_{2} -1 + C +4 O_{2} + H_{2} +1 O -2$
None of the element changes its O.N. and hence option (b) is correct.
