1. ### 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...
2. ### Lithium and Fluoride ionic bond

Can someone please help me explain in a simple way what happens to both these elements after a ionic bond. Thanks.
3. ### 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.
4. ### Balance/Net Ionic

Can someone help with these double displacement and neutralization reactions. I need someone to figure out if there is a reaction, if so write out the net ionic equation. Write out the products w states. & balance them. if there is not a reaction, what are the spectator ions. 1) Li2CO3(aq) +...
5. ### Ionic strength in organic solvent?

Can a solution of an organic solvent have ionic strength when there's a salt such as aliquat 336 dissolved in it?
6. ### Complete and Net Ionic Equations

This is for a lab: find the balanced molecular, complete ionic, and net ionic equations: 1. NaHCO3 (aq) + CuSO4 (aq) 2. NaHCO3 (aq) + Pb(NO3)2(aq) 1. Molecular: 2NaHCO3 (aq) + CuSO4 (aq) => Cu(HCO3)2 (s?) + Na2SO4 (aq) Complete Ionic: ? Net Ionic: ? Name the spectator ions, and reaction...
7. ### 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...
8. ### net ionic equations, need help asap

this is due in like 5 hours, need help with these. 1.Consider the reaction when aqueous solutions of magnesium sulfate and calcium iodide are combined. The net ionic equation for this reaction is: 2.Consider the reaction when aqueous solutions of calcium acetate and zinc sulfate are...
9. ### 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...
10. ### 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...

Bones are mostly calcium phosphate. Calcium chloride reacts with potassium phosphate to form calcium phosphate and potassium chloride. Determine the total IONIC equation for the reaction stated above WITH PHYSICAL STATES
12. ### 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...
13. ### HELP needed: Calculation the pKs1 for H2S in various ionic water according to Hearshe

HELP needed: Calculating the pKs1 for H2S in various ionic waters I need the pKs for H2S in a water body containing Na,K,Mg,Ca,Cl,SO4,HCO3 with an ionic strenght of 1.5 and 28 C°. It should be possible to calculate this according to the paper of Hearshey and Millero (1988), The pK1* for...
14. ### 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...
15. ### Chemistry- Reaction of Ions

A student mixes four drops of an aqueous solution of Pb(NO3)2 with 4 drops of an aqueous solution of (NH4)2 CrO4 in a chem plate. A bright yellow solid appears immediately upon mixing. Write complete molecular, complete ionic, and net ionic equations for the reaction. Identify the spectator...
16. ### 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...
17. ### Ionic Compounds?? HELP!!

. Look at the the label of any household item (cereal, shampoo, can of soup, etc.). identify 2 ionic compounds in the item. Identify the item of your study or no credit will be given. Well first I was like hey this will be easy name something that has a ionic compound in it and put the...
18. ### ionic and covalent bonds

which compounds have both ionic and covalent bonds? 1) sodium sulphate 2)carbon monoxide 3) ethanol ethanoate 4) magnesium floride the answer is 1) but why? also how do you derive this type of answers in future like in other questions?
19. ### 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...
