What is the balanced equation for sulfur dioxide and water vapor?
Equation SO2 + H2O ----> H2SO3 (Sulfurous acid) Having water as vapour does not change the formula in anyway so keep it simple
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
Why's the boiling point of hydrogen sulfide slightly higher than hydrogen selenide?
Sulfur is not nearly as electronegative as oxygen so that hydrogen sulfide is not nearly as polar as water. Because of this, comparatively weak intermolecular forces exist for H2S and the melting and boiling points are much lower than they are in water.
What is the first ionization of hydrogen sulfide?
H2S(g) + H20(l) ---> H3O+(aq) + HS-(aq) or H2S(g)+ aq ---> H+(aq) + HS-(aq) or H2S(aq) ---> H+(aq) + HS-(aq) Bitch please,it's so simple. As simple as ABC. Go do some revision.
Is h2o alive?
No, H2o is water, so it is not alive. But it does carry living things, although it is technically not alive.
Why the structure of H2S and H2O so similar?

Difference between dibasic acid and diprotic acid?
They both mean the same thing:acid molecules with 2 protons: e.g. H2O and H2S and ....H2S --> H+ + HS-HS- --> H+ + S2-The two sulfides (HS- and S2-) are both base, so H2S is dibasic (= forming two bases)Two protons are freed, so H2S is diprotic (= forming two protons)
What smells like faeces?
Actually, the gas that sometimes contaminates natural gas and oil well call hydrogen sulfide (H2S). H2S is also a byproduct of mammalian digestion, so anything containing H2S will smell similar.
Is H2S O2 equal to S H2O?
I'm no chemist, but I do know that you need to balance the sides in this and add another oxygen molecule to the products. the result would be S+H2O2 or SO+H2O (I think).
Hydrobromic acid and water?
HBr + H2O ----> H3O+ + Br-According to the Brownsted-Lowry definition, acidsare substances that donate H+ ions and bases are substances that accept H+ ions. The HBr gives away a H+ to the H2O making it Hydronium (H3O+), so that makes the HBr an acid and the H2O a base.
Why are the structures CH4 and SiH4 so similar?
Both have no lone pairs.They have even bonds
What is the formula for the conjugate base of HSO3-?
S-
Why are homologous series of carbon compound so called?
They are said to be homologous because they have similar structures.
Structures that have similar structure and function but different evolutionary origins are called?
It is either homologous structures or homozygous structures. Embryological structures are when different species of animals look similar in the earliest stage of development and Analogous structures are when animals look different but their function is basically the same. So just look up homologous structures and homozygous structures in your Bio book!!
Why H2S is more acidic than H2O?
Its because of electronegativity. Hydrogen is very positive. Oxygen and Sulfur are very negative. Oxygen is more negative, though, than sulfur. Because of this, oxygen holds onto the hydrogen better than sulfur. So H2S is a stronger acid because sulfur can't hang onto that hydrogen as well as oxygen can. Remember, to be a good acid, you need to be able to loose your hydrogen atoms.
In testing rockets why were chimps used instead of other?
Because their bodies are like humans. They have similar structures to us, so if they can survive, so can we.
