Consider the chemical reaction of methane combustion:
wCH_(4)+xO_(2)->yCO_(2)+zH_(2)O.(a) Write a system of 3 equations in the 4 variables
w,x,y,zthat represents the reaction. Each equation represents an element whose quantity is conserved. (b) Find a solution to the system different from the trivial solution
w=
x=y=z=0.
