Question

a reaction involves the following elementary steps:

\\\text{h}_2(g) + \text{o}_2(g) \longrightarrow \text{h}_2\text{o}_2(g)\\
\\\text{h}_2(g) + \text{h}_2\text{o}_2(g) \longrightarrow 2\text{h}_2\text{o}(g)\\

part 1 (1 point)
what is the sum of the two reactions, retaining all chemical species? remember to include states of matter.

part 2 (1 point)
what is the net reaction when reactive intermediates are cancelled? please include states of matter.

Answer:

Question 1

\(2\mathrm{H}_2(g) + \mathrm{O}_2(g) + \mathrm{H}_2\mathrm{O}_2(g)
ightarrow \mathrm{H}_2\mathrm{O}_2(g) + 2\mathrm{H}_2\mathrm{O}(g)\)

Question 2

\(2\mathrm{H}_2(g) + \mathrm{O}_2(g)
ightarrow 2\mathrm{H}_2\mathrm{O}(g)\)
