Question

A reaction involves the following elementary steps:

Answer 1

Answer:

Explanation:

      H₂$_{g}$ + O₂$_{g}$ → H₂O₂$_{g}$

      H₂$_{g}$ + H₂O₂$_{g}$ → 2H₂O$_{g}$

The sum of the two equations is a combined equation where all the compounds on the reactant sides are written on the Left hand side and the products are all on the right hand side:

•         H₂$_{g}$ + O₂$_{g}$ + H₂$_{g}$ + H₂O₂$_{g}$ → H₂O₂$_{g}$ + 2H₂O$_{g}$

• The net reaction equation involves the cancellation of species that occurs on both sides, these species are H₂O₂:

     We then have:

    H₂$_{g}$ + H₂$_{g}$ + O₂$_{g}$ → 2H₂O$_{g}$

        combining the two repeating hydrogen gas:

                    2H₂$_{g}$ + O₂$_{g}$ → 2H₂O$_{g}$
