midsize D Posted April 9, 2008 Share Posted April 9, 2008 I dont understand how to do this so i need yalls help, Write the Correct Name of The Following Formulas: 1. Calcium Chlorine 2. Copper Sulfate 3. Nickel Oxide Im not goina ask for u guyz to do my home work but i would like some examples please Link to comment Share on other sites More sharing options...
swansont Posted April 9, 2008 Share Posted April 9, 2008 If I'm understanding the question properly, if it were "DiHydrogen Monoxide" the answer would be "water." So I guess each of those are assumed to have a more common name. I'm assuming if they wanted the formula, they'd ask for the formula (e.g. H2O) rather than the name Link to comment Share on other sites More sharing options...
midsize D Posted April 9, 2008 Author Share Posted April 9, 2008 It has to be something like CH3Co-2 or something like that, its so freaking confusing i wish i could be smart science whizzes like you guyz Link to comment Share on other sites More sharing options...
insane_alien Posted April 9, 2008 Share Posted April 9, 2008 so, do you want the correct name (ie Sodium Cholride) or the formula (ie NaCl)? Link to comment Share on other sites More sharing options...
midsize D Posted April 9, 2008 Author Share Posted April 9, 2008 The formula for the names listed above its more like chemistry because he wants the Ion Formulas for the names Link to comment Share on other sites More sharing options...
insane_alien Posted April 9, 2008 Share Posted April 9, 2008 well, it is chemistry seeing as they are chemicals. do you know about valences at all? and there are two possible answers for the last one, were there any roman numerals along side the nickel part?

midsize D Posted April 9, 2008 Author Share Posted April 9, 2008 yea, i remeber he said something about valences. But there where no roman numerals it was just Nickel Oxide I think that is Type I Link to comment Share on other sites More sharing options...
swansont Posted April 9, 2008 Share Posted April 9, 2008 If it's the chemical formula, then you have to decide how the pairs will combine. Sodium and Chlorine form an ionic bond, with each having one electron given/taken, so the formula is NaCl. You have to figure that out for the other atoms or molecules.

thedarkshade Posted April 9, 2008 Share Posted April 9, 2008 You just need to know the oxidation numbers, of the elements and based on that you can then put the indexes to equalize those oxidation numbers and this gets you to the correct formula.
