Question

2H2 + O2 → 2H2O

Given 1.0 moles of O2, how many grams of H2O can be produced ?

Answer 1

Answer:

2H2O2 --> O2 + 2H2O

It is decomposition of hydrogen peroxide into oxygen.

It can also be described a reaction showing how H2O2 acts as a reducing agent

H2O2(aq) ---------> O2(g)  + 2H^+ (aq)  + 2e  E = + 1.77 V

2h2 O2 2h2o
