Asked by Wilson - Fri Nov 2 15:38:04 2007 - - 2 Answers - 0 Comments

A. The ion acetate is CH3COO- Ni(CH3COO)2 The ion carbonate is CO32- Cu2CO3 NOTE : CH3CH2O- is an alkoxide so Ni(OCH2CH3)2 is Ni(II) alkoxide

Asked by Nikita P - Thu Dec 6 17:57:12 2007 - - 2 Answers - 0 Comments

A. I have a feeling that you are just asking us to do your homework for you, but here are some hints. First, each compound listed is ionic, so the first step is to determine the charge of each ion. For the monoatomic ions in the s block (i.e. Sr and K) you look at the column the atom appears in on the periodic table. For instance, potassium, which is in the first row, has a charge of 1 positive. Strontium has a charge of 2+. For the transition metals Co, Ag, Fe, and Cu you determine the charge by looking at the roman numerals which come after the written element. For instance, in copper(II) sulfate, the Cu ion has a 2+ charge. Some transition metals only have one charge, so the roman numerals are omitted (silver only ever has a… [cont.]

A. How can you pass summer school if you can't even spell "school"? This looks remarkably like a boatload of homework, and we aren't in the business of doing your homework for you. I rather like helping students understand some sticky point of chemistry, but I'm not about to do all of your work for you. Even the questions are bogus. Look at the first one... "1. Although phosphorus (Z = 15) can be found in compounds with various charges..." Phosphorous isn't found with ANY charges in a compound. Phosphorous forms covalent bonds, even with the alkali metals, therefore, it never has an ionic charge in a compound. Phosphorous DOES exhibit an oxidation number of -3 in many compounds, which is what I suspect that the question is fishing for.… [cont.]

Asked by 123 - Tue Jan 6 23:47:02 2009 - - 1 Answers - 0 Comments

A. 2. (and 4) Balancing an equation means having the equal amounts of each element on each side. You can't create or destroy elements in a simple chemical reaction. All these equations have to be balanced because one of the reactants is a dimer gas molecule. To be balanced, the coefficients in front of each reactant and product has to be integral. In #1, as written, there is too much "O' on the left. If we double the amount of SO3 on the right, We have twice as much S on the right, so we can double the amount on the left. Now we have both S and O in balance. Thus, 2 SO2 + O2 -> 2 SO3. In #2, we need to double the Fe on the right, as each unit of Fe2O3 provides 2 Fe. However, the O is still unbalanced. So we triple the H2O to… [cont.]
