Answer: Option B

Explanation:

The molecules that is described in the model is water H_{2}O and other molecule is O_{2} molecule.

Due to difference in electronegativity of hydrogen atom and oxygen atom there is partial positive charge on each hydrogen atom and partial negative charge on oxygen atom of O_{2} molecule.

Hence, water is a polar molecule.

Whereas in O_{2}, there is covalent bonding due to sharing of electrons. Hence, this molecule is covalend and hence, it is neutral in nature.

Therefore,  O_{2} is a non-polar molecule.

So, both the molecules are put together in the container then there will be no attraction in between them because water molecules contains charge but oxygen molecules does not contain any charge as they are neutral.

Thus, we can conclude that one molecule is polar and other is non polar so they do not attract each other.

hi i am on the student board committee at my school and I'm having to ask people their thoughts on the LGBT+ community i have to
-BARSIC- [3]
Supporting the LGBTQ+ community is important because queer people can't choose their circumstances. It's not their fault that they're the way they are (not that it's bad). It also helps to decrease suicide rates, due to the fact that they seem more accepted. Aside from the fact that I am bisexual, I think that it's important to judge a person for who they are, not gender dysmorphia or sexuality.
