    Ok I need some verification on this so i don't go nuts. These are all in aqueous solutions

    Combine............ bum bum bummmm

    Magnesium nitrate and sodium hydroxide

    Formula equation: Mg(NO3)2 + 2NaOH ---> 2NaNO3 + Mg(OH)2

    Total Ionic eq: Mg + 2NO3 + 2Na + 2OH ---> 2Na + 2NO3 + Mg(OH)2

    Net Ionic eq: Mg + 2OH ---> Mg(OH)2

    Sorry, I didn't put the charges (or whatever they are called lol) but i don't know how to do superscripts.

    Also, what I assume this means is that when you combine the two aqueous solutions, you will get a precipitate Mg(OH)2.

    Your ionic equatiosn are fine, your last sentence doesn't make sense.

    If you combine the two, wont the precipitate be Mg(OH)2

    As far as I remember the hydroxide molecule is soluble in water.

    Doesn't look like it according to my manual

    Your manual knows better than me then.
    If theres a precipitate, its the magnesium hydroxide.
