What are the properties of hydrogen sulfide gas?
However, it is a highly corrosive, flammable and poisonous gas. Hydrogen sulphide is most commonly formed due to the microbial breakdown of organic matter in the absence of oxygen….Overview.
|Density||1.363 g dm-3|
|Melting point||−82 °C (−116 °F; 191 K)|
|Boiling point||−60 °C (−76 °F; 213 K)|
What are two physical characteristics of hydrogen sulfide?
Hydrogen sulfide is a colorless, flammable, highly toxic gas. It is shipped as a liquefied, compressed gas. It has a characteristic rotten-egg odor that is detectable at concentrations as low as 0.5 ppb.
Is hydrogen sulfide gas flammable?
Hydrogen sulfide (also known as H2S, sewer gas, swamp gas, stink damp, and sour damp) is a colorless gas known for its pungent “rotten egg” odor at low concentrations. It is extremely flammable and highly toxic. Hydrogen sulfide also occurs naturally in sewers, manure pits, well water, oil and gas wells, and volcanoes.
What is the characteristics Odour of H2S gas?
Hydrogen sulfide (H2S) is a colourless gas with a characteristic odour of rotten eggs which being denser than air may pool in low areas in still conditions.
What are the properties of hydrogen?
Physical properties of Hydrogen: The hydrogen gas is colourless, odourless and tasteless in nature. It is a combustible gas but not a supporter of combustion. It is lighter than air and insoluble in water. It has an atomic mass of 1.008 amu and an ionization enthalpy of 1312 kJ mol-1.
What are hydrogens physical properties?

What is hydrogen sulfide gas used for?
Hydrogen sulfide is used in several industries and is a by-product of many industrial processes including oil refining, mining, tanning, wood pulp processing, food processing, craft paper production, and rayon manufacturing.
How much hydrogen sulfide is in a fart?
0.001 PPM to 1 PPM
Bacteria breaks down organic components inside our stomachs into hydrogen sulphide (H2S), which gives the infamous ‘rotten eggs smell’. For us, this meant that we needed to detect trace amounts of hydrogen sulphide. A fart contains from 0.001 PPM to 1 PPM of H2S (indeed, the human nose is very sensitive).
Is hydrogen sulfide a good conductor of electricity?
At pressures above 90 GPa (gigapascal), hydrogen sulfide becomes a metallic conductor of electricity.
What are three chemical properties hydrogen?
At standard temperature and pressure, hydrogen is a nontoxic, nonmetallic, odorless, tasteless, colorless, and highly combustible diatomic gas with the molecular formula H2. Hydrogen is also prevalent on Earth in the form of chemical compounds such as hydrocarbons and water.
What are 5 physical properties of hydrogen?
Hydrogen is a colourless, odourless, non-metallic, tasteless, extremely flammable diatomic gas with molecular formula H2 at standard temperature and pressure.
What are 2 chemical properties of hydrogen?
Properties: Common hydrogen has a molecular weight of 2,01594 g. As a gas it has a density of 0.071 g/l at 0ºC and 1 atm. Its relative density, compared with that of the air, is 0.0695. Hydrogen is the most flammable of all the known substances.
