what is difference between h2o and h2s.
the only thing i can say about this is that water is a polar bond becaue the bonds cant cancel out.
H2S also is a polar covalent bond. It's tough to know what you want when you say difference. H2S has a rotten egg smell and pure water does not. H2S is a gas at room temperature, H2O is a liquid. Here is a site to read more about H2S. I assume you know most of the properties of water.

The difference between H2O and H2S lies in their chemical composition and properties. H2O refers to water, while H2S refers to hydrogen sulfide. Here's a brief explanation of their differences:
1. Chemical Formula: H2O has two hydrogen atoms bonded to one oxygen atom, while H2S has two hydrogen atoms bonded to one sulfur atom.
2. Molecular Shape: H2O has a bent or V-shaped molecular structure due to the presence of two lone pairs of electrons on the oxygen atom. This leads to a polar molecule, as the electronegativity difference between hydrogen and oxygen causes an uneven distribution of charge. H2S has an angular molecular structure, similar to H2O, due to the presence of two lone pairs of electrons on the sulfur atom. However, the electronegativity difference between hydrogen and sulfur is smaller, making H2S less polar than H2O.
3. Physical Properties: Due to the polar nature of the H2O molecule, it exhibits many unique properties such as high boiling and melting points, surface tension, and solvent capabilities. Water also has a higher heat capacity and density than hydrogen sulfide. On the other hand, H2S is a toxic gas with a characteristic foul odor, similar to the smell of rotten eggs.
In summary, the key difference between H2O and H2S is their respective chemical compositions and properties, with water being a polar molecule and an important compound for life, while hydrogen sulfide is a toxic gas.
