Final answer:

To balance the chemical equation Fe2(SO4)3 + 3 K(SCN)2 → 3 K3Fe(SCN)6 + 2 K2SO4, you need to make sure that the number of atoms of each element is the same on both sides of the equation.

Step-by-step explanation:

To balance the chemical equation Fe2(SO4)3 + 3 K(SCN)2 → 3 K3Fe(SCN)6 + 2 K2SO4, you need to make sure that the number of atoms of each element is the same on both sides of the equation. Here is the step-by-step process:

  1. Count the number of atoms of each element on the left and right sides of the equation: Fe: 2 on the left, 6 on the right; S: 12 on the left, 6 on the right; O: 12 on the left, 8 on the right; K: 6 on the left, 6 on the right; SCN: 6 on the left, 18 on the right.
  2. Start by balancing the elements that appear in the fewest compounds. We can balance the K by placing a coefficient of 3 in front of K(SCN)2 to get 3 K(SCN)2.
  3. Next, balance the Fe by placing a coefficient of 3 in front of Fe2(SO4)3 to get 3 Fe2(SO4)3.
  4. Now, check if the atoms of each element are balanced. Fe: 6 on both sides; S: 12 on both sides; O: 12 on both sides; K: 18 on both sides; SCN: 18 on both sides.

Therefore, the balanced chemical equation is: 3 Fe2(SO4)3 + 3 K(SCN)2 → 3 K3Fe(SCN)6 + 2 K2SO4
