Chemistry and system of equations

  1. Oct 19, 2005 #1
    Hi,
    I want to kow if it is possible to convert a chemical equation ( unbalanced)
    into a matrix and solve this matrix to find the coeficient of the equations to balance the equations.
    For example:
    H2SO4+MnS+As2(Cr2O7)5---->HMnO4+AsH3+Cr2(SO4)3+H2O
    How to convert it into a matrix of unknowns to find the balanced coefficients?
    Thank you
    B

    Can you present your thoughts on the matter first?

    Thanks.

    I think That I need to produce an system of equation with the coefficient as the coefficient of the molecules ( for each element)
    for H : 2, 0, 0, -1, -3, 0, -2
    for S : 1, 1, 0, 0, 0, -3, 0
    for O :4, 0, 35, -4, 0, -12, -1
    for Mn : 0, 1, 0, -1, 0, 0 , 0
    for As : 0, 0, 2, 0, -1, 0, 0
    for Cr : 0, 0, 10, 0, 0, -2, 0
    I don't know if I am right , but when I solve this system , I get some negative coefficients which makes no sense.
    Please can you help me to understand what is going on here?
    Thank you
    B.
