# fes2 compound name

================ Follow up ================. What does mbs adj on a bank statement mean? Hydropyrite. If you wanted to be pedantic, it's nickel(II) disulfide, but there isn't any other kind, so most of the time chemists just leave out the (II), because it's not actually ambiguous. FeS. Wait. Cupric: Term. Should I use constitute or constitutes here? But it's *not* an ionic complex of nickel(IV) and [S]2– anions, and it's *not* named nickel (IV) sulfide. Auriferous pyrite is a valuable ore of gold. All Rights Reserved. I have a 1993 penny it appears to be half copper half zink is this possible?

In your case, the logic is: S usually forms a monoatomic ion [S]2–, so two of them is four minuses, so you need Ni(IV). an anion. Join Yahoo Answers and get 100 points today. This is supported by measurements and calculations of the electron density, which show significant electron density between the atoms. Pyrite is the most common of the sulfide minerals.

Does someone know which of those is 'true', or better, if there is another, more detailed explanation? Level. • FeS2 + 2Cl2 … Fe Provide the symbol and charge of the polyatomic sulfur ion present in FeS2?

Iron (II) sulfide, sticks, >=95% FeS basis. Sie können Ihre Einstellungen jederzeit ändern. Join Yahoo Answers and get 100 points today. Now, grab a periodic table and look for sulfur. Why didn't the Imperial fleet detect the Millennium Falcon on the back of the star destroyer? You can sign in to vote the answer. Why are bonds ionic when the electronegativity difference between bonded atoms is greater than 1.7? The resulting atom charges then represent the oxidation state for each atom. The oxidation number of any atom in its elemental form is 0. The idea is that you should be able to assume the charge on the anion: F– Cl– [O]2– and so forth, and if you know that, you can infer the charge on the metal. 18. A type of compartment that rises out of a desk. Why don't libraries smell like bookstores?

Just like pyrite is FeS2 but it's not Fe(IV) either.

If you wanted to be pedantic, it's nickel(II) disulfide, but there isn't any other kind, so most of the time chemists just leave out the (II), because it's not actually ambiguous. Asking for help, clarification, or responding to other answers. Fe3S4 could be thought of as a mixture of FeS and Fe2S3, since there is no iron in the +4 oxidation state. Thanks for contributing an answer to Chemistry Stack Exchange! I have searched all over the web and found a lot of diverse explanations, but none of them are concluding exactly whether $\ce{FeS2}$ (solid - pyrite) is a covalent or an ionic compound.

This name is likely due to the sparks that result when pyrite is struck against steel or flint. In the Carlin, Nevada gold deposit, arsenian pyrite contains up to 0.37 wt% gold. But it's *not* an ionic complex of nickel(IV) and [S]2– anions, and it's *not* named nickel (IV) sulfide. Create your own flash cards! Clearly, they can't all be "iron sulfide", so there must be some way to distinguish between them in the name. From electronegativity, it should be covalent as the $\Delta\chi=0.7$ which is less than $1.5$ and thus said to make covalent bonds and therefore be a covalent compound. The mineral pyrite, or iron pyrite, is an iron sulfide with the formula FeS2. Description. Why does the enthalpy of the reaction depend on the moles of the limiting reagent. Example Reactions: • 2H2S + FeO = FeS2 + H2O + H2.
