We are taught in school that H2+O2 always give us 2H2O  {2 molecules of water} but why not it forms H2O2 (hydrogen peroxide)? Please explain.

Thanks for asking us a question in Ask the Expert section of TopperLearning.com.

2H2 and O2 always give 2H2O (2 molecules of water) as this is the most feasible reaction.
In stringent conditions only, H2 and O2 can produce H2O2 (hydrogen peroxide).
