Question

balance the following chemical equation
Fe2(So4)3 + KSCN = K3Fe(SCN)6 + K2So4

my answer:
Fe2(So4)3 + 12 KSCN = 2 K3Fe(SCN)6 + 3 K2So4

is my answer correct?

Answer 1

You should NEVER need to ask if an equation is balanced. You check it.
1. Atoms must balance.
2. Electrons, if a redox equation must balance.
3. The charge on both sides should balance.
Fe2II(So4)3 + 12 KSCN = 2 K3Fe(SCN)6 + 3 K2So4
I see 2 Fe on each side
I see 3 SO4^2- on both sides.
I see 12 on left and right.
I see 12 SCN^- on both sides.
I see zero charge on left and right.
This is not a redox equation.
Everything looks OK to me. Good job. The nice thing about balancing equations is that you ALWAYS know if you are right or not.
