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?
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.
What are 2 carbon-containing gases that are significant as greenhouse gases?
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.
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.
Give mechanism for the reduction of NO2 to NH2.?
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.
What is the balance equation for hydrogen gas and iodine gas?
The balanced equation for the reaction between hydrogen gas (H2) and iodine gas (I2) to form hydrogen iodide gas (HI) is: H2 + I2 → 2HI
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 would happen to the rate of a reaction with rate law ratek NO2 H2 if the concentration of H2 were halved?
In the rate law given as rate = k[NO2][H2], the reaction rate is directly proportional to the concentration of both NO2 and H2. If the concentration of H2 is halved, the reaction rate would also be halved, assuming the concentration of NO2 remains constant. This is because the rate depends linearly on the concentration of H2, so any decrease in H2 concentration results in a proportional decrease in the overall reaction rate.
What will form when NO2 react with HCl?
nacl2+h2
What would happen to the rate of a reaction with rate law rate kNO2 H2 if the concentration of no were halved?
In the given rate law, the rate of the reaction is proportional to the concentration of NO2 raised to the power of 1 and the concentration of H2 raised to the power of 1, represented as rate = k[NO2][H2]. If the concentration of NO2 is halved, the rate of the reaction would also be halved, assuming the concentration of H2 remains constant. This is because the rate directly depends on the concentration of NO2, leading to a linear decrease in the reaction rate with a decrease in its concentration.
What would happen to the rate of a reaction with rate law rate k NO2 H2 if the concentration of NO were halved?
In the given rate law, the rate of the reaction is dependent on the concentrations of NO2 and H2. If the concentration of NO were halved, it would not directly affect the reaction rate since NO is not included in the rate law. Therefore, the rate of the reaction would remain unchanged, as it only depends on the concentrations of NO2 and H2.
What is the equation for the incomplete combustion of hydrogen?
The equation for the incomplete combustion of hydrogen is 2H₂ + O₂ -> 2H₂O + energy (incomplete combustion).
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.
Water is composed of what two gases?
Hydrogen(H2) and Oxygen(O2)
