Answer:
Hydrogen gas can be produced through various chemical reactions, such as the electrolysis of water, the steam reforming of natural gas or other hydrocarbons, and the reaction of certain metals with acids. However, without knowing the specific reactions mentioned in your question, I cannot definitively say whether any of them could have produced the hydrogen gas used in the Hindenburg.
It should be noted that the use of hydrogen gas as a lifting gas for airships was common at the time, despite its flammability. The Hindenburg disaster led to a significant shift in the use of alternative lifting gases, such as helium, which is non-flammable.
