Question

How many electrons does a single hydrogen gain or lose in the following reaction?

H2 + O2 - H20

Answer 1

One electron per single hydrogen atom.

Step-by-step explanation:

Hello!

In this case, given the reaction:

`H_2+O_2\rightarrow H_2O`

Whereas we can identify the following half-reaction for hydrogen:

`H_2^0\rightarrow H_2^+`

Whereas we see that each single hydrogen atom gains one electron in order to go from 0 to +1, which is also related to an oxidation half-reaction.

Best regards!
