Nice!

Anyway,did the test tube broke own its own or it is broken by someone?

@kuro96inlaila

It broke on its own. The test tubes broke in about one of two experiments. The product is FeS and it melts during the reaction. Melting point of FeS is ~1200 °C. So, its quite exothermic.

That's awesome!!

It's even better than the barking dog demonstration.

Thank you very much for sharing.

Just one question, is the product of the reaction FeS or Fe3S4?

I'd like to work out the stoichiometry.

@yellowmetalcyborg

Fe + S --> FeS

The product can be used to produce H2S gas.

@DoktorKlawonn Ok, thank you.
