    Mimicing an Aurora borealis effect

    Hi gurus, I am new to this forum and excited about learning from the vast knowledge here! I have a challenge that I hope is interesting to help solve: I would like to mimic the Aurora Borealis inside a small flat plastic cylinder. I envision this as constantly flowing liquids moving around...

    How does the electromotive force effect the electron for the band gap to change, to i

    How does the electromotive force effect the electron for the band gap to change, to increase, and decrease.? someone told me on a forum, "It takes energy, either in the form of light, heat or electromotive force to move electrons from one energy level to a higher one, while they will typically...

    Question about the common ion effect

    A bit of theory to refresh your mind about the solubility product: Ks = the given solubility constant example: Ks = [Pb2+].[I-]^2 7,1*10^(-3) = [Pb2+].[I-]^2 -> The solubility of this compound is then: S= (Ks/4)^1/3 = 1,2 mol/L Now my question: What is the solubility of Ag2SO4 (Ks...

    Organic Chemistry: Inductive effect vs Mesomeric Effect

    I was asked to build a table featuring EWG and EDG of common functional groups , arranging them by its "power". First a table of decreasing Inductive effect; secondly a table of decreasing mesomeric effect and at last a table comparing them and defining "decreasing" Electron Withdrawal Power...

    Common Ion Effect

    What mass of Mg(OH)2 will dissolve in 1.0 L of 0.050 mol/L solution of MgSo4(aq)? Here is my work I just want to know if my calculations are correct. Mg(OH)2 <--> Mg^2+ + 2(OH-) Ksp= [Mg^2+][OH-]^2 = 5.6X10^-12 ICE Molar Solubility | [Mg^2+] | [OH-]^2 Initial...
