what are the values of a,b,c and d in the balanced chemical equation
aFe^2+(aq)+bAl(s)=cFe(s)+dAl^3+(aq)
where a,b,c and d are the lowest possible whole numbers?
a=
b=
c=
d=

  • chemistry help plz -

    Each Fe+2 ion gets two electrons
    Each Al loses three electrons. So, for each three Fe+2 ions, one must have two Al atoms.

    a=3
    b=2
    c=3
    d=2

    3Fe+2 +2Al(s)=3Fe(s)+2Al+3(aq)
