    Does Polyprotic Strong Acid Completely Dissociate in a Net Ionic Equation?

    I have to write net ionic equations for reactions. I have a big question to ask about polyprotic strong acids. Do we assume that the acid completely dissociates in a net ionic equation, such as H3PO4 and H2SO4? aluminum chloride + sulfuric acid -> aluminum sulfate + hydrogen chloride I...

    Verifying Reasoning for AQ Solutions and Water's Presence in Net Ionic Equations

    i would like to see if my reasoning is correct (for aq. solutions): 2HBr_(aq_) + 2NH_3_(aq_) -> 2NH_4_(aq_) + Br_2_(aq_) HBR is an acid so it gives H to NH3, which leaves Br all alone. But Br can't exist by itself, so it becoems Br2? ionic: 2H^+_(aq_) + 2Br^-_(aq_) + 2NH^-_3_(aq_) ->...

    Ionic Charge and the Periodic Table

    Hi we're beggining to label the orbitals with s p d structures...grade 11 chemistry The question is "Explain why the 2+ ion is the one that tends typically to form" Ive answered the question above this one which says "Ca element 20 forms a 2+ ion. Write the electron configuration of neutral...

    Writing balanced net ionic equations

    can anyone write the balanced net ionic equations for the following reactions in acid solution?? thanks.. i can't figure it out 1. solid phosphorus (P4) reacts with hypochlorous acid (HClO) to form phosphoric acid H3PO4, and chloride ion 2. Tellurium, Te, is oxidized by nitrate ion to form...

    Writing Net Ionic Equations for Acid-Base Reactions

    can some tell me how to write net ionic equations of acid base recations in the cases of a weak base reacts with a strong acid, a strong base reacting with a weak acid, and weak base reacting with weak acid? How do you cancel things out? Also, does NH3+HCl--->NH4Cl or NH3+HCl--->NH4+Cl-?

    How Do You Write Net Ionic Equations for These Reactions?

    The directions say to give the net ionic equation for the principal reaction. I did the first couple right (I think) but don't know how to proceed: (the part by the number is the question and my answer is 2 spaces below) 1. NH4Ac(aq) + HCl(aq) -> ? H+ + AC- -> HAc 2. NH4F(s) +...

    How to combine elements of differing ionic charge

    It's easy when say zinc is +2 and chloride is -1, so it is ZCL2 However, say I wanted to combine say, oxygen and gold. Gold has +1 and +3 and oxygen is -2, which of the gold do I use? (+1 or +3, for example)

    Understanding Naming Ionic Formulas: Parentheses and Roman Numerals Explained

    Okay, I am so confused about how to determine whether or not you have to use the parenthesis with the Roman numeral. It is confusing me because some of the compounds that I have to write the name for, are ternary compounds, and I'm not sure which order they go in. :confused:

    Net ionic equations with no ions

    Just a short question: Now the molecular equation between LiOH (aq) with HBr (aq) is (I presume): LiOH (aq) + HBr (aq) ----> LiBr (aq) + H(2)O (l) Now I'm confused about the net ionic, since there are no ions. Would it just be: OH(-) + H(+) ---> H(2)O?

    Net Ionic Eqn for NaOCl & Na2S2O3 Reaction: Calculate Enthalpy Change

    What is the net ionic equation for the reaction of 0.5M solution of sodium hypochlorite and 0.5M solution of sodium thiosulfate? Calculate the enthalpy change. I have a very terrible chemistry teacher. I haven't learned how to write ionic equations yet, but he wants this assignment for marks...

    VSEPR Theory: Investigating Ionic Molecules

    Vsepr Theory Hey Guys! How are u guys doing today? I was wondering how do we know dat BeF2 is polar?..i drew it out by using the VSEPR theory..but what confuses me is dat BeF2 ionic..can we still use VSEPR theory to draw it out? Tanya Thank you in advance! :smile:

    Is Bed Length in Ionic Chromatography the Height of the Column or the Matrix?

    is bed length the heigh of the column or is that the heigh of the matrix/gel? i don't know where to put this question, but since it is about proteins then i guess here is the place :approve: thanks!

    Oxidation number vs. ionic charges

    what is the difference between oxidation number and ionic charges? I realize they are written differently, +1 vs. 1+, but how can I reasonably explain the differnces to 17 year olds (and myself?)?

    What is the method for determining the oxidation number of transition elements?

    oxidation number of transition elements. I know the oxidation number of non-metallic elements. But :confused: How do I know the oxidation number of transition elements. Such as Fe and Cr Cr = 4s1 3d5 when Cr change to Cr2+ Cr3+ Is it stable?

    A simple question about Covalent Bond and Ionic Bond

    I started reading a book about the basic foundations of chemistry, and I came up across a simple question. To answer this question you should understand that there are variable valencies, which is what this question consists of. If you look at the cuprous chloride compound CuCl, copper has...

    Why is there a difference in atomic and ionic radii for Ca and Zn?

    hey guys! I was just wondering if anyone could help me out a bit on this. I have the following radii (in angstroms...not that it really matters) Ca: 1.74 Ca 2+: .99 Zn: 1.31 Zn 2+: .74 Does anyone have any idea why the difference between the atomic radii of the two elements is...

    Understanding Ionic Charges for Na, Cl, and Other Particles

    I'm having a terribly difficult time figuring this out and I'm (ashamedly) sure it is quiet simple. How do I know or figure out the ionic charge of a particle. Such as Na or Cl. How do I know if they are a minus 1 or positve 2 or what they are?
