Chemistry Question on hydrogen peroxide

The reaction, 2H2O2→2H2O+O2;2H_{2}O_{2} \to 2H_{2}O +O_{2} ; shows that H2O2H_{2}O_{2}

A

is decomposed

B

acts as oxidising agent

C

acts as reducing agent

D

none of the above

Answer

is decomposed

Explanation

Solution

H2O2H_2O_2 decomposes on standing or heating (auto oxidation reduction). 2H2O2−1−>2H2 {2H_2\overset{-1}{O_2} -> 2H2} O−2+O2 {\overset{-2}{O} +O_2}
