H2 molecule is the least polar.
Between H2O and H2S, the most polar will be H2O as oxygen is more electronegative than sulphur.
HS2 is nonexistent. H2S is polar.
It is not using H2S gas. It is using H2O liquid.
h2so4 being good oxidising agent oxidises the h2s to h2o and free sulphur.so conc h2so4 cant be used in preparation of h2s gas
H2o,co2,so2,h2,co,h2s,hcl,hf
Oxygen (O) is more electronegative than sulfur (S). This means that H2O more polar than H2S. This means that the forces of attraction between H2O molecules is grater than that in H2S molecules, making it harder to separate them from one another to turn it into a gas.
H2O is more polar as oxygen is more electronegative than sulfur and will therefore attract the electrons more than sulfur
Oxygen is more electronegative than sulfur, resulting in more polar bonds with hydrogen.
NH3 is more polar than AsH3, this is the same as comparing H2O and H2S.
intermolecular hydrogen bonding that is prsnt in H2O while absnt in H2S....:)
H2S is a polar compound.It is not ionic.
H2 [Hydrogen] is not polar.
Polar
HS2 is nonexistent. H2S is polar.
Strongest---------------> Weakest HI, HCl, H2S, H2O According to MasteringChemistry.com
H2S and NO2H2sNO2-
The bond angle for H2S is 92.1­°.
It is not using H2S gas. It is using H2O liquid.
