ANSWER:Step 1 of 3
The decomposition of hydrogen peroxide \({{\rm{H}}_{\rm{2}}}{{\rm{O}}_{\rm{2}}}\) to give hydrogen \({{\rm{H}}_{\rm{2}}}\) and oxygen \({{\rm{O}}_{\rm{2}}}\). is represented by the following balanced chemical equation.
\({{\rm{H}}_{\rm{2}}}{{\rm{O}}_{\rm{2}}} \to {{\rm{H}}_{\rm{2}}} + {{\rm{O}}_{\rm{2}}} \)
One mole of \({{\rm{H}}_{\rm{2}}}{{\rm{O}}_{\rm{2}}}\) decomposes to give one mole of \({{\rm{H}}_{\rm{2}}}\) and one mole of \({{\rm{O}}_{\rm{2}}}\).
