    Hey all you Chemistry people out there, I call upon you to assist me, please.

    Mg(NO3)2;N2;NH3;BH3

    I need to write an essay on the intra-molecular bonding in each and how this in turn influences the inter-molecular forces within the molecules mentioned above.

    Then I have to talk about the solubility of each within a polar/non-polar medium. compare and contrast how the shape affect this solubility.

    I know the basics of teh first part except for NH3. Does it use Hydrogen bonding or instantaneous dipole van der Waal (London) forces? Secondly: How does intra molecular bonding influence inter-molecualr bonding in general?

    Finally: In general how does shape affect solubility? Does it have to do with valency?

    Also: what does Mg(NO3)2 look like (the molecular structure)
    :D Hope you guys can help:apple:

    Have you tried wikipedia?

    If that doesn't help, sorry I sucked at chemistry. I do like blowing stuff up though :D

    WIkipedia explains things at third year university level :( I'm in grade 11 and need someone to help in basicer terms than those of the wiki!

    try chemfinder.com

    Mg (NO3)2 is Magnesium Nitrate.

    Thats completely incorrect. Wikipedia should not even be consulted at University level. It is useful for general knowledge of a subject only.

    Janet Stemwedel is posting about molecule polarity on her blog right now. She's a chem Ph.D. and a great writer, so I'd trust what she says.

    And this weekend, she says she's going to write about intermolecular forces, so there you go!
