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?
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.
Yes, your answer is correct. By balancing the equation, you have ensured that the number of atoms of each element is equal on both sides of the equation.
To check if your answer is correct, we need to make sure that both sides of the chemical equation have an equal number of atoms for each element. Let's break down the equation and count the atoms:
Fe2(So4)3 + 12 KSCN = 2 K3Fe(SCN)6 + 3 K2So4
On the left side:
- Fe: 2
- S: 3
- O: 12
- K: 12
- N: 12
On the right side:
- Fe: 2
- S: 3
- O: 12
- K: 6
- N: 12
Based on this count, we can see that there is an imbalance in the number of potassium (K) atoms on both sides of the equation.
To balance it, we need to adjust the coefficient in front of K2SO4 on the right side. In this case, the coefficient should be 6, not 3.
So, the balanced equation is:
Fe2(So4)3 + 12 KSCN = 2 K3Fe(SCN)6 + 6 K2So4
