Question

How do I show the + and - ends for H2S, a polar molecule?

Answer 1

How did you figure this out though?

Answer 2

You can use the oxidation numbers to help determine the charges of these ions

Answer 3

Can you demonstrate for this specific example?

Answer 4

H2F?

Answer 5

Ok. H has the oxidation number of +1, so it is positive. S has the oxidation number of -2, so it is negative. Therefore, the molecule is positive on the H ends and negative on the S end.

Answer 6

If you know about electronegativity, you can also use it to explain why H2S is polar

Answer 7

I will look into this later. Thanks dude, here's your medal.

Answer 8

You are welcome. And thanks.
