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

What does Calcium metal added to nitrous acid form?
Ca + 2HNO2 ------> Ca(NO2)2 + H2
What are 2 carbon-containing gases that are significant as greenhouse gases?
Carbon dioxide (O=C=O) and methane (H2-C-H2) or [CH4].
Give mechanism for the reduction of NO2 to NH2.?
Reduction by use of H2, Pd/C, or Zn, HCL. Either or.
What gases did Oparin think were in the earth's early atmosphere?
( h2; ch4; nh3)
What are two molecules of hydrogen represented by?
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.
How can one distinguish between the gases H2 and NO2?
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.
What is the mole fraction of NO2 in a mixture of gases made up of 5.0 g of NO2 10g of SO2 and 1.5 g of H2?
0.108
Which are the gases in the periodic table?
H2.He,Kr,Ne,Ar,Xe,Rd,O2,N2,NO,NO2,N2O,CO2,SO2,H2S,SO3
What is the equation for the incomplete combustion of hydrogen?
exc. H2 + nO2 ---> 2nH2O + exc. H2.
What will form when NO2 react with HCl?
nacl2+h2
What does Calcium metal added to nitrous acid form?
Ca + 2HNO2 ------> Ca(NO2)2 + H2

Is gas atom or an molecule?
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.
What gases is on the earth?
H2,CI,O3,CO2,O,and NO
What gases are not greenhouse gas?
Greenhouse gases must have three atoms, so gases like hydrogen (H2) and Oxygen (O2) are not greenhouse gases.
What gas do acids form when they react with metals?
Usually hydrogen (H2). Nitric acid usually gives NO or NO2, depending on concentration.
