    Understanding lewis structure answer

    The following picture is a posted solution to an earlier exam, The question was to draw Ca (s) + Br2 (g) = CaBr2 as a lewis structure, the suggested answer was like this: I understand that this forms an ionic bond given that Ca (metal) donated electrons to Br (non metal) and becomes...

    Ionic Solids Conductivity

    I have no idea what might be an answer to letter a. Also, I think letter b has something to do with the fact that , in general, cations are smaller than anions, but it feels like something is missing. Thanks for taking the time to read this and I hope you help me in this question.

    distinguishing ionic vs covalent

    Despite my username, I am a Chemistry Dummy, so here's my simple question. I'm trying to develop the ability to easily and reliably determine if a compound is ionic or covalent based on either the name or the formula. Here's what I've noticed seem to be true as general rules: Ionic will...

    How to find the net ionic equation

    Molecular Equation: Pb(OH)2(s) + 2HCl(aq) -> PbCl2(s) + 2H2O(liquid) Total Ionic Equation: Pb(OH)2(s) + 2H(aq) + 2Cl(aq) -> PbCl2(s) + 2H2O(liquid) Net Ionic Equation: ??? Would the net ionic equation be the same as the total ionic equation in this case, since there appear to be no spectator...

    conductivity offline determination via ionic strength

    Hi, I am looking for a way to adjust the conductivity in a bioreactor system by adding WFI. The problem is that a online measurement is not possible in this system, i.e. a certain amount of WFI has to be added to the system, then mixing occurs and then a sample is taken and the conductivity is...

    Why aren't Ionic Compounds Molecules?

    Okay I understand why ionic compounds are ionic compounds and that is the ionic bonding. What I don't understand is why this isn't a subset of the molecules. They have these properties that some molecules share: Negative and Positive parts High Solubility in water Forms a lattice in the...

    Sodium Chloride - Neutral or Ionic and Why?

    I know that sodium chloride solubilized in water is an electrolyte - meaning it conducts electricity when dissolved in water. I think this means that table salt is an ion, because it carries electrical charge. I get confused because I thought a definition of a salt was an ionic compound that...

    net ionic equation

    write the net ionic equation for the reaction of acetic acid CH3COOH with KOH i thought it would be H+(aq) + OH-(aq) = H2O(l). I thought this because i thought that acetic acid in solution has an acetate species CH3COO- and H+. and that the acetate ion is a spectator ion, that is present...

    Predicting lattice energies of ionic compounds with oxyanions...?

    So I know that lattice energy is closely related to electric potential... the lattice energy of an ionic compound is proportional to the product of the charges on its irons and inversely proportional to the bond length. Now what if the anion from the ionic compound is a polyatomic oxyanion...
