Hey everyone! can some one explain to me if my teacher is right? so we're just learning how to add, or valence chemical equations, and the procude, or what comes out of the reaction is less then what we first started with in the checmical reaction, if I can recal, the formula was 2k(HI)2 (that right there is a subscript btw...+2k(IoH)2= 2K,Io 2 (subscript) OH.....what is she talking about.....or , what I am really asking is...Am I right? I said that the electrons were replaced or went somewere else..

whats loH? please use capitals where needed

anonymous · Answer

Ah yes! my bad, Iodine

anonymous · Answer

No need to solve it, it was just an example, all im asking really, or was, WAS,  is what she's teaching us is correct

anonymous · Answer

It was just valencing equations, and I actually quite get it, the example up there is wrong by the way. thank you however, any comments on it though?

aaronq · Answer

balancing chemical equations?

you must end up with the same number of atoms on both sides, law of conservation mass

anonymous · Answer

yes, im a freshman you see? nothing especial really, we we're just learned how to make chemical bonds using a method that resembles the ball and stick model, and now we moved on to this, and yes! but its more like were we try to valance the equations by adding exponenenets BEHIND atoms or bonds, like this 2H, (were 2 is the number that multiplies all the elements..) and the result, or *produces* of the chemical equation are less the number of atoms that we had to start with

anonymous · Answer

and hence to valence the equation we needed to add coefficients multiplying the number of elements in a bond, I would show you an example but I turned the sheet in already.

anonymous · Answer

I was just really confused in all honesty....I believe this is just a step to solving more chemical equations, her teaching methods are quire predictable...

aaronq · Answer

no this is how you balance (it's balance by the way, valence refers to the outermost electrons) you add coefficients to the front of the molecule.. 

try it:

OH^- + H3O^+ <-> H2O

aaronq · Answer

you can't add numbers between the atoms because you would be changing the molecule in itself

anonymous · Answer

yes, I see, therefore to valence the equation you must do have an equal number of atoms in the compound.

anonymous · Answer

ok, and im sorry, what is ^,<> in the equation stand for?

anonymous · Answer

OH-+? we mostly have equtions like OH+???= whats your way of writing these equations?

aaronq · Answer

the ^ means superscript, sorry il re write it

anonymous · Answer

hmm ok, thank you for your time by the way, I feel like knowing everything today I guess...

aaronq · Answer

$$OH ^{-} + H _{3}O ^{+} \rightarrow H _{2}O$$

anonymous · Answer

Is the answer (2)h2o?

aaronq · Answer

yep that reaction is called the self-ionization of water where pH=7 .. i mean you seem like you get it, wanna try a harder one?

anonymous · Answer

I see, we took notes on that today in class to, I appreciate all your help Aaron and I hope you have a nice day!

aaronq · Answer

haha no prob dude, have a good one !
