Determining products and their percentages
« on: January 26, 2009, 04:40:28 PM »
I introduced a different form of this question under the High School section, refer me back there if this is not up to par?
30% HCl solution (infer 70% HOH?) 2HOH + 'HCl' + 4Na ==> NaCl + NaOH + NaH + NaO + H2
I apologise, I only had a moment to jot this down in a notebook, and now I see it's unbalanced.
What I am attempting to ask is that when this reaction is complete, are all of these products necessarily produced, and in what %s.
As I wrote in the parallel forum, this is a demonstrative reaction for something else
I am working on.
The general question I should ask is that if a product *could* be produced in a reaction does that necessarily mean it will be?

Yes.  Just getting elements on both sides of the equation is not enough to ensure the reaction goes forward.  There are other rules.  For example, Na metal reacts with water, to from NaOH.  NaOH reacts with HCl to from NaCl.  You can't get sodium hydride, or sodium oxide if there is water or HCl around.
Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.

Can I assert that if the condition of the chemicals being combined and their products are 'manipulated' -Temp, Pressure, and such; That I can increase the chances of having a higher yeild of the product I desire?
I am most confident this is true.  I will post this question in the hope it may help others, althought I know I am in the company of those much more knowlegeable than myself.

You can change some things, sometimes, to get what you want.  If you do a quick wikipedia search or google search, you'll find the recipies for industrial production of sodium oxide, or sodium hydride.

Thank you for your continued help Arkcon.
     I earlier showed a reaction involving HOH, Na, and HCl.
If I want to actually execute this reaction... can I balance it, then multiply reactants by their % composition.  That is if I have a 30% HCl and 70% HOH solution, may I multiply their coefficients by 30 and 70 respectively, and calculate the number of grams of Na to complete the reaction.  This seems logical to me, but I am a newbie.
     It occurs to me that this may make it easier to calculate yield, but extremely work intensive to balance the products.
     I like to have a full grasp on what I am doing, but it seems easier to send samples to a company that advertises on the 'sidelines' here.  Do you have any info on the accuracy of I.M.R.?

Apologies for posting after myself again.
It occurred to me that if I balance reactants/products in the traditional sense, that it is an empirical formula, and I should be able to increase one or more of the reactants just as long as it is done in a identical proportion with the others.  Or is this a major mistake?

I really can't understand what you're trying to do, from your various posts, since your arrival on this board.  You appear not to have basic university, or even advanced high school, chemistry knowledge.  That's no big deal, lots of the new kids, on this board, have come here to get some help with their classes.  Presumably, when they're done with their questions here, and their studies in class, they do know these concepts.  You also appear to be trying to make some sort of invention, based on some concepts, revolving around chemistry.  Lots of people come here to do that too.  I don't want to discourage you, or make you think I'm trying to act elitist -- but really, without the basics, or a well defined plan, you're not going to get anywhere.  You appear to want to not give too many secrets away, but from what you've told us, I don't see how you're going to accomplish anything.  So I really don't have any answers for you, except you can try to keep reading the basic questions asked by others, that we've answered, and try to answer them yourself, and see how they apply to your particular application.  Unless, you want to be complete transparent in what you're trying to accomplish.

     I had some training in Chemistry when I was younger, I did take Chem 1 and 2 in college, and started OChem, but could not seem to master that subject.
     Arkcon, the major problem I have as that this education was around 20 years ago.  I am stumbling around here because it is as if I am learning to walk again, in a relearning chemistry sense.
     I may be asking simple questions, and putting my foot in my mouth a lot, I do have an idea I am working on, that is getting more and more difficult to bring to completion due to my ignorance of the current subject matter I am dealing with: solid/solid separation.  I have found a pertanent web site, but have not had time to utilize it.
     I do not know what else to say at this point, I just hope it will not bother anyone if I try to participate here for as long as possible.  I have a healthy respect for Chemistry, and Chemists, and will do my best to exercise patience, persistence, and a positive mental attitude.

Well, that was a lengthy block of mine, because I felt I had to be clear, and encouraging, and not too impolite.

You could answer the question I asked twice in the text block.  What, exactly, are you trying to do?

What Arkcon is trying to say is that we get people every now and then who have a great idea for an invention.  Problem is, they don't have the chemical knowledge to develop it themselves without help.  So, they come here, BUT they don't want to give away too much info because they don't want their idea scooped.  The whole process is frustrating for us, because we have to try to answer your questions without knowing the whole story.

Arkcon suggested two choices:

1)  Tell us the whole story, and we can then discuss the feasibility of your project

or

2)  Go read the basic questions people are asking, and see if you can learn information yourself, and then come back with questions that make more chemical sense, because like Arkcon said, it's not really making a ton of sense.

     I need to think about what to tell you and how to tell it.  It is based on simple chemical fact and a opening market.  I need some time to deside wheather or not to give up and make it public, or stick it out and try to make money.  Almost a year ago, I promised myself I would spend at least 5 years on my process, I want to be true to myself.  So, after writing all of this I have decided to remain silent.
     I am however interested in a collaborator who would share equally in patent(s) and money.  This venture will need to be documented as in Partnership Agreements and  Confidentiality Agreements.  If this Plan is to work, my Partner would need to hold a Ph.D, due to the fact that ordering and selling bulk chemicals is involved.  That is all I have for now.  I need to make dinner.
