okay, we can see in the other way, if you have enough chemicals to use for those (H2 and H2S) --method 1: you can use your nose to smell it, the H2S has the smell, like ... rotten eggs, smell it and you will see, lol, but especially that is really harmful, the other one is H2
--method 2: you can use CuO (black) include heat, so with heat, the H2 makes the CuO turn red, because H2+CuO --> Cu+ H2O, because the red color is the color of Cu, the other one is H2S
--method 3: we use the H2S , we put the AgNO3 (aq) we can see the H2S reacts with the AgNO3 and we see the black color, because AgNO3 + H2S --> Ag2S + 2HNO3, the black color is the color of Ag2S after reaction, with H2, it can not react with AgNO3, I'm not sure about this one because, if H2 reacts with AgNO3 , the products are HNO3 and Ag, but HNO3 is the strong acid, so the products will become the reactants, so jsut look the black color in the test tube which belong to the Ag2S
we have many other ways to distinguish these one, but with me these methods is enough for you to be easy to distinguish H2 and H2S
When calcium metal is added to nitrous acid (HNO2), it will form calcium nitrite (Ca(NO2)2), water (H2O), and nitrogen dioxide (NO2) gas as the products. This is a redox reaction where calcium is oxidized, and nitrous acid is reduced.
Carbon dioxide (CO2) and methane (CH4) are two significant carbon-containing greenhouse gases that contribute to global warming and climate change. These gases trap heat in the Earth's atmosphere, leading to the greenhouse effect.
Two molecules of hydrogen arte represented by '2H2'. This means H2 & H2 . 'H2' is ONE molecule of hydrogen . It consists of two(2) atoms of hydrogen . It can be represented by 'H-H'. NB With the exception of the Noble Gases , all other gas molecules contain at least two atoms.
The reduction of NO2 to NH2 involves adding hydrogen gas in the presence of a metal catalyst such as platinum or palladium. The hydrogen gas reacts with the nitro group to form an intermediate compound, which then undergoes further reduction steps to yield the amino group. This process is commonly known as catalytic hydrogenation.
The balanced equation for the reaction between hydrogen gas (H2) and iodine gas (I2) to form hydrogen iodide gas (HI) is: H2 + I2 → 2HI
H2 is odorless, while H2S has a foul odor resembling rotten eggs. H2 rises to the ceiling, while H2S sinks to the floor. H2 is harmless, while H2S is poisonous. H2 is not corrosive, while H2S is. Colder than -70°C, H2 is still gas, while H2S is liquid.

The equation for the incomplete combustion of hydrogen is 2H₂ + O₂ -> 2H₂O + energy (incomplete combustion).
H2,CI,O3,CO2,O,and NO
Neon is an element on the Periodic Table, so it is an atom. It would have to be joined with a different atom to make a molecule.
Greenhouse gases must have three atoms, so gases like hydrogen (H2) and Oxygen (O2) are not greenhouse gases.
Hydrogen(H2) and Oxygen(O2)
Hydrogen H2; nitrogen, N2; oxygen, O2; fluorine, F2; chlorine, Cl2
We use haber process for it. We use H2 and N2 gases.
