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.
