liho+h2s=
Sodium (Na) has been reduced.
6
2 plus 2 equal 4
71 plus 23 plus 49 is equal to 143.
liho+h2s=
There are 2 sulfur atoms in the chemical reaction H2S plus SO2 plus H2.
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
H2s+c2=
This is H2S + CuSO4 = CuS (s) + H2SO4.
CuNO3 + Ag

Ag+
# CaCO3 - calcium carbonate # FeSO3 - iron (II) sulfite # NaOH - sodium hydroxide # H2S - hydrogen sulfide # AgNO3 - silver nitrate
Al and AgNO3. Al has a 3plus charge plus 3e negative. 3(Ag positive plus le negative equals Ag). Al plus 3Ag plus is equal to Al with a 3 plus charge plus 3Ag.
FeS + 2H+ -> Fe2+ + H2S
I cannot answer this question.
