Question

$H_{2}S$ is a gas while $H_{2}O$ is liquid. Explain.

Answer 1

Intermolecular forces. Silicon dioxide is really strange with its shape. You'd assume it to be linear like carbon dioxide but it holds a more tetrahedral orientation. This polarizes the molecule and helps them form complex chains of silicon dioxide. It's hard to find black and white information on this as many articles will contradict each other. But we do use silica as a polar surface for TLC and glass does have a slight attraction to water.

So I guess that's the answer. Silicon dioxide is polar. Carbon dioxide is not.

Answer 2

$H_{2}S$ Please make it as brainliest
