H2 + H2O ->??

I suspect that it creates H30+ but I don't know if H can exist on it's own as an H

H2+ H2O=> H3O+ + H

H would be possitive

H2+ H2O=> H3O+ + H+

The reaction you provided is incomplete, as it does not specify the reactants involved. However, I can help explain how to determine the products of a reaction.

To predict the products of a chemical reaction, you need to consider the type of reaction and the reactivity of the elements or compounds involved. In this case, it seems you are trying to determine the products of a reaction between hydrogen gas (H2) and water (H2O).

To determine the products, we need to understand the possible types of reactions that can occur between these substances. One possibility is a displacement reaction, where hydrogen gas displaces another element from water. This would result in the formation of a metal hydroxide and hydrogen gas.

For example, if you have a reactive metal like sodium (Na), the reaction can be represented as follows:

2Na + 2H2O -> 2NaOH + H2

In this reaction, two molecules of sodium react with two molecules of water to produce two molecules of sodium hydroxide (NaOH) and one molecule of hydrogen gas (H2).

Please note that the specific products may vary depending on the reaction conditions (e.g., temperature, pressure, and catalysts). The reaction you provided is not balanced or complete, so it is essential to provide more information or check the reaction conditions to determine the specific products accurately.
