Ok I need some verification on this so i don't go nuts. These are all in aqueous solutions
Combine... bum bum bummmm
Magnesium nitrate and sodium hydroxide
Formula equation: Mg(NO3)2 + 2NaOH ---> 2NaNO3 + Mg(OH)2
Total Ionic eq: Mg + 2NO3 + 2Na + 2OH ---> 2Na + 2NO3 + Mg(OH)2...
I need to write the NIE for these:
1. "0.1M lead nitrate, Pb\left(NO_3\right)_2 and 1.0M sodium chloride, NaCl."
2. "6M sodium hydroxide, NaOH, is added to 0.5M ammonium chloride, NH_4Cl."
For the first one, I set up the following equation (not balanced)...
Hi All,
Here is my first question: (according to the picture)
A vat is filled with water and ions. The vat contains two compartments separated with a thin layer (green) (50 nanometer).
On a side there is p1 (positive ions) and n1 negative ones,
the other side contains p2 and n2 ions...
Hello,
I am am working on my grade 12 chemistry course ALMOST DONE YEAHH!
I am stuck ona few questions, and I am hoping to get some help even if you just tell me where to begin on solving these.
1) If the Ka=1.8 * 10^{5} for acetic acid ( ie. CH_{3}COOH), what is the H^{+} ion concentration...
So I've read about these Lifters that lots of crazies attribute to antigravity or whatever. Obviously we know that it's caused by the ionic wind.
But how does that work, exactly?
http://www.blazelabs.com/l-vacuum.asp I read says that the high voltage of the top conductor ionizes air (by...
Just need some idea of where to start on this one...am in my first Chemistry class and it is an intensive so we're not spending a lot of time on things. This one just has me stumped from the beginning so just some guidance on where to begin would be a huge help...
Problem: Gold metal will...
Now obviously, ionic bonds are "weaker" than covalent bonds, but my question is that according to the attached image, you can't necessarily have crystals being formed in a covelant bond as you would in an ionic bond, right? And also, when an ionic bond occurs, what makes it possible for a...
hi, I'm studying for the chemistry SAT and have a question that I'm not sure that I've done right...can someone please check my answer...thanks in advance!
Write a net ionic equation for the following:
a) Chromium dipped into silver nitrate
b) Aluminmum dropped into a bath of sulphuric...
hi can somebody show me how to do this ionic equation thanks.
first of all the equation is
Na2Co3 + H2s04 -> Na2S04 + H20 + C02
i think the main parts are H20(l) and CO2(g) how do i do an ionic equation would i do
Co32- + 2H+ -> H20(l) + Co2(g)
please tell me if this is right thanks
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...
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_) ->...
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...
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...
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-?
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) +...
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)
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:
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?
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
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 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!
well here is the question:
Manganese Dioxide, MnO2, was fused with Sodium Hydroxide, NaOH, and an oxidising agent potassium chlorate(v), KCLO3. The result was a green solid containing K2MnO4, and potassium chloride, KCL. This mixture was powdered and boiled with water through which carbon...
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?)?
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?
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...
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...
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?
