Hi
One of the possible approach is to find the simultaneous equations of coefficients of the chemical equationa nd solve those equations using solve function. For example, for your case:
x1(C2H6)+x2(O2)=x3(CO2)+x4(H2O)
Then the equations will be:
2*x1=x3; %Equating C coefficients
6*x1=2*x4; %Equating H coefficients
2*x2=2*x3+x4; %Equating O coefficients
Since these are 3 equations and 4 variable. The solution require the ratio of unknowns, so you can put x4=1 and then solve these equations and divide the solution with smaller value of unknown to get the ratio. Moreover, it becomes Ax=b system, you can also solve it using inv function, i.e
x=inv(A)*b;
Hope it will help!
