The H2S auto explosive limit between (4.3 - 46)%,this called explosive mixture for hydrogen sulfied.
The pH of a solution containing H2S would be acidic, as H2S is a weak acid. The exact pH value would depend on the concentration of H2S in the solution.
The formula for hydrosulfuric acid is H2S.
To find the number of moles of hydrogen sulfide, divide the given mass by the molar mass of hydrogen sulfide. The molar mass of hydrogen sulfide is approximately 34.08 g/mol. Thus, 64.6 g / 34.08 g/mol = 1.9 moles of hydrogen sulfide in the sample.
Dihydrogen sulfide H2S is a diprotic weak acid.
The balanced equation for the reaction between iron(II) sulfide (FeS), hydrochloric acid (HCl), and hydrogen sulfide (H2S) is: FeS + 2HCl + H2S --> FeCl2 + H2S
Lel Chamel was created in 2010.
Martin Lel was born on 1978-10-29.
Katya Lel's birth name is Yekaterina Nikolayevna Chuprinina.
100% LEL is 5 %. So 10 % of it is 0.5%

The Lower Explosive Limit (LEL) of ethanol is approximately 3.3% volume concentration in air. This means that if the concentration of ethanol in the air is below 3.3%, it is too low to ignite and sustain combustion.
As per Osha, in a confined space, less than 10 percent LEL is considered safe
