I can't answer this question because the problem is incomplete; no choices were given. Luckily, I found a similar problem from another website which I've attached as a picture down below. An ion-dipole bond results when one dipole molecule is present with an ion in the solution. Water is a dipole molecule. Now, CH₃OH, an alcohol, is a nonelectrolyte. It doesn't dissociate into ions when solvated. On the otherhand, Ca(NO₃)₂ dissociates into Ca²⁺ and 2 NO₃⁻ ions.
<em>Therefore, the answer is Ca(NO₃)₂.</em>
When:
Fe(OH)3 ↔
Fe3+ + 3OH-so, each 1 mol Fe3+ → 3 mol OH-
and when [OH]
= 1.2 x 10^-5∴ [Fe3+] = (1.2 x 10^-5) / 3
= 4 x 10^-6when
Keq = [Fe3+][OH]^3 = (4 x 10^-6) (1.2 x 10^-5)^3
∴Keq = 6.9 x 10^-21
A I don’t know how to explain it but I just know that it’s A
The first image has a higher frequency because the wavelengths are shorter. This means that the disarmament between two crests (tops of waves) are closer together than the other waves. Hope this helps and mark brainliest if you can! Thanks!
Calcium sulfate, carbon dioxide, and water are produced when sulfuric acid and calcium carbonate interact.
<h3>What results from the reaction of calcium carbonate and sulfuric acid?</h3>
The insoluble in water free lime (CaCO3) interacts with sulfuric acid. It takes only a few minutes for sulfuric acid and lime to react and produce gypsum. H2SO4 + Lime CaCO3 = CaSO4 (gypsum).
<h3>What occurs when calcium and sulfuric acid are combined?</h3>
Each of these metals forms a layer of insoluble sulfate when exposed to sulfuric acid, which slows or stops the reaction altogether. A white precipitate of calcium sulfate and a small amount of hydrogen are formed in the calcium case.
