How many grams of sulfur can be prepared from 1.40 kg of H2S?
1.40 kg is equal to 1.40 / 0.03418= 40.96 mole H2S, thus 40.96 mole of S (sulfur) which is 40.96 * 0.03207= 1.31 mole S(0.03418 and 0.03207 are molar masses of H2S and S respectively in kg/mol)
How does the experimental mole ratio compare with the theoretical mole ratio?
the experimental mole ratio has a bigger penis
Why is silver jewelry tarnishing a chemical change?
Because it is a reaction on the silver surface between silver and hydrogen sulphide (H2S); the result is the silver sulphide (Ag2S), a black compound.
What is a balance chemical equation for Silver (Ag) tarnishes when it reacts with hydrogen sulfide (H2S) molecules in the air?
Ag2O----Actually, silver oxides exists as silver peroxide (AgO) or silver oxide (Ag2O)
The atomic ratio is almost equal to the mole ratio of zinc to iron?
Yes.
How would you balance the following equation Ag H2S Ag2S H2?
The balanced equation is as follows: 2Ag + H2S --> Ag2S + H2
What does AgNo3 plus H2S equal?
Ag2S + 2HNO3

How many moles of hydrogen sulfide are contained in a 64.6-g sample of this gas?
H2S 63.1 g H2S * 1 mol H2S / 34.076 g H2S = 1.85 mol H2S
In the reation 8H2 S8 ----- 8H2S what is the ratio H2 to H2S?
1
What is the volume of oxygen required for complete combustion of 0.5 liter of H2S at stp?
For gases it is valid that the Volume ratio of reactants and products is the same as the mole ratio (in the balanced equation) when pressure and Temperature are kept coonstant. This is according to the general gas law (Boyle-Gay-Lussac): p.V = m.R.T2H2S + 3O2 --> 2H2O + 2SO2so 0.5 L H2S needs 0.5 * [3/2] = 0.75 L O2
How many moles of oxygen are needed to react completely with 2.3 moles of H2S 2H2S plus 3O2 2SO2 plus 2H2O?
H2S (g) + 2 O2 (g) --> H2SO4 (l) 1 mole + 2 mole --> 1 mole You will need 2 moles of O2
How do you distinguish between the gases H2 and No2?
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 is the mole ratio of salt to water in NA2SO4.10H2O?
An anhydrous sals hasn't water.
