Chemical Equation Balance using Linear Algebra 13 Years Ago by michaelzip Hi. Can you help me how to balance a chemical equation using linear algebra. I know how to do it … don't have a problem anymore on extracting the values, chemical symbols, and coefficients. My professor gave me until May 10… Re: How to write a program in C++ which balances chemical equations? 14 Years Ago by Clinton Portis …string symbol; string temp; term package; chemical compound; //Extract any leading coefficient while…leading_co += bunch_of_terms[i]; i++; } do{ //Extract Chemical Symbology while(isalpha(bunch_of_terms[i])) { symbol += bunch_of_terms[i… Balancing chemical equations 14 Years Ago by dejandenib … solution for this? the program should output how can the chemical equation be balanced (which are the coefficients) 28th ACM International… Collegiate Programming Contest, 2003-2004 Asia Region, Tehran Site Balanced Chemical Equations Sample Input 3 HCl+CaO2H2=CaCl2+H2O HCl+H2SO4… Generalized matrix inverse method for balancing chemical equation and their stability 14 Years Ago by rahul.nutron … have to develop a c program which can balance a chemical equation by the method of 'Generalized matrix inverse method for… balancing chemical equation and their stability'.

However, I don't need help on parsing a… working on. I also know that I can balance a chemical equation mathematically using matrices and a set of simultaneous equaations… Programming Chemical Equations 3 Years Ago by Rudrakshi Rajalaxmi I have checked various sites about, "**How to balance chemical equations thru programming by usiong python or c++ ?**." They all have simple easy equations, but how do we programme Chemical Equations which consist **Ions/ Hydrates**. If some one knows how to do that please respond. A slight idea can help me too. Re: How to write a program in C++ which balances chemical equations? 14 Years Ago by Clinton Portis I am intruiged with this assignment.. although it's been years since I balanced a chemical equation.. I would find this to be a fun challenge. You teach me how to balance chemical equations.. I'll give you some code. Start me off with something simple.. and I'll code you an answer (as much as I can in accordance with daniweb policy.) How to write a program in C++ which balances chemical equations? 14 Years Ago by coldkiller I am working on a equation balancer for my 12th class computer science project.But somehow i am not able to balance the chemical equation.Please if anyone can provide me the source code it will be a great help.Urgently needed!

Then we can probably help you reflect that algorithm as pseudo code that you can fairly easily implement in a number of programming languages. Re: Chemical Equation Balance using Linear Algebra 13 Years Ago by michaelzip I will use the example above, Fe + Cl2 = FeCl3 Fe on left hand side has 1 atom, same with the right hand side so they are equal. Cl on left hand side has 2 atoms, and 3 atoms on the right hand side. To make Cl equal, I am adding 3 more Cl on left hand, and 2 on the right hand so that makes [B]Fe + [U]3[/U]Cl2 = [U]2[/U]FeCl3.[/B] They aren't … Re: Balancing chemical equations 14 Years Ago by TeejMonster A bit of a tall order. An application like this (written from scratch) would take a lot of work. First, it would have to be able to recognize individual elements symbolically, then it would have to iterate through solutions and reduce. Why not take a whack at it yourself and then post if you get stuck? Re: Balancing chemical equations 14 Years Ago by aidvllasaliu I agree with TeejMonster! Re: Generalized matrix inverse method for balancing chemical equation and their stability 14 Years Ago by rahul8590 a similar problem has already been asked in this forum [URL="http://www.daniweb.com/forums/thread238596.html"]http://www.daniweb.com/forums/thread238596.html[/URL] i guess u will find ur answer there Re: Balancing a Chemical Equation in Java 11 Years Ago by bguild Start by counting the number of substances involved, including both reactants and products. That will be the number of columns of your matrix. Since your equation is already parsed, I expect that number is easily obtained. Next you create a list of the elements involved. For example if H2O is a product then that would mean H and O would need to be… Re: Programming Chemical Equations 3 Years Ago by rproffitt I don't see how to condense all you would need to know in this space. Looking at https://pythoninchemistry.org it appears you spend quite a few months working at this. Re: How to write a program in C++ which balances chemical equations? 14 Years Ago by coldkiller Balancing a equation is quite easy. Like take this equation for an example Al + O2 = Al2O3 Oxygen gas is diatomic, which means that the oxygen atoms, like policemen, go around in pairs. A molecule of aluminium oxide consists of two aluminium atoms combined with three oxygen atoms. Actually, technically the word "molecule" is … Re: How to write a program in C++ which balances chemical equations? 14 Years Ago by coldkiller There are also redox reactions which include balancing through electrons and oxidation state,but that is not needed because it will make the program very complex and lengthy. Re: How to write a program in C++ which balances chemical equations? 14 Years Ago by Clinton Portis [quote] 1. We'll have to prompt for an equation that we can understand. We can identify individual reactants easily. We can assume than any compound that begins with a number is a coefficient, any subsequent numbers in the compound will be subscripts. With this protocol established, we can make life a little simpler for the user in that they can … Re: How to write a program in C++ which balances chemical equations? 14 Years Ago by Clinton Portis This: [CODE] #define LEFT TRUE; #define RIGHT FALSE; [/CODE] should be this: [CODE] #define LEFT TRUE #define RIGHT FALSE [/CODE] Re: How to write a program in C++ which balances chemical equations? 14 Years Ago by coldkiller thanks clinton portis the code was really a big help and at last i created 1st of my list of projects and ya thanks again for complementing my copy/paste skills.I use turbo C++ and many of the functions that you defined were not available in it but it was not a big problem.Cheers Re: How to write a program in C++ which balances chemical equations? 10 Years Ago by naveen.nagabhushan How to modify this for C ? There is no scope resolution operator in C. Please help Re: How to write a program in C++ which balances chemical equations? 10 Years Ago by Lerner To clarify terminology, I think of the scope resolution operator in C++ as the double colon, ::. I don't see that in Clinton's code, but I may have missed it. That being said: 1) Don't resurrect dead code. If you want to base your code off of this post, then start your own post sections of code you don't understand. 2) Porting code from one … Re: How to write a program in C++ which balances chemical equations? 7 Years Ago by Maria Noel Can you please please help me on how to make a program that can balance equation?
