How do you name chemicals using the -ous or -ic notation?
Q. I have to name the following chemicals for chemistry: a. Sns b. SnS2 c. CoCl3 d. CoCl3 e. HgBr2 Hg2Br2 How do you name these chemicals using the -ous or -ic notation
Asked by Matthew - Sat Apr 14 11:46:29 2007 - - 4 Answers - 0 Comments
A. The -ous designation goes to the metal with the lower oxidation state, the -ic designation to the higher oxidation state. a. Stannous sulfide b. Stannic sulfide c. (I think you mean CoCl2 here) Cobaltous chloride d. Cobaltic chloride e. Mercuric bromide f. Mercurous bromide

How to convert each quantity into Moles of Sulfur??? HELP!!!?
Q. I must round off correctly and ahow calculation setup. I did a few on my own, but these are a little complicated for me. Any help would be appreciated. 1.) 2 moles of SnS2? 2.) 3.01 times 10 to the 23rd power molecules of H2S? 3.) How many grams of O in 2.10 moles of H3PO4(aq)? 4.) How many moles of H in 1.20 moles of H3PO4(aq)? 5.) How many moles is 49.00 grams of H3PO4(aq)? How many molecules is that? 6.) Okay, for this one, I did the first part of it which is: Convert 5.40 grams of boron to moles? The answer I got was 0.500 mol of B(Boron) right? Now the next part says: How many atoms of boron is that? So, I multiply 6.02 times 0.500 mol B and the answer I got was 3.10 times ten to the 23rd… [cont.]

A. first determine if the compound is ionic or covalent. Ionic is a bond between a metal and non-metal and Covalent is a bond between 2 non-metals. If it is ionic: (SnS2) 1. name the first element : Tin 2. name the second element with a "ide" suffix : sulfur => sulfide 3. assign charges to the metal if it is a Transition mental : since sulfur always has a -2 charge and there is 2 of them Tin must have a +4 charge to balance it or IV (in roman numerals) 4. just put it together : Tin (IV) sulfide If it is covalent: (P2O5) 1. name the first element : phosphorus 2. name the second element with a "ide" suffix : oxygen => oxide 3. assign prefix's based on the number of each element : P2 => Di O5 => pent 4. just put it together : Diphosphorus… [cont.]

A. 1. A strong electrolyte is a material that conducts electricity very well when dissolved in an aqueous solution. Electrolytes are generally ions and usually conduct electricity very well in their molten state (though are usually insulators in their solid state). 2. "Like dissolves Like:" in a nonpolar solvent, a nonpolar solute will dissolve best. Cl4 is the only nonpolar compound on that list. (a) and (b) are both ionic compounds, and water is a polar compound as well due to the non-symmetrical distribution on hydrogens attached to the oxygen 3. The answer is (a), because there are three ions for every molecule of the compound when dissolved in solution. (b), (c), and (d) only have two ions per original molecule.
