Question

Is this equation balanced?

3kBr + FeCl3 -> FeBr + 3KCl

A) No, it’s not balanced. The K atoms are not balanced.

B) Yes, it’s balanced.

C) No, it’s not balanced. The Br atoms are not balanced.

D) No, it’s not balanced. The Fe atoms are not balanced.

Answer 1

The given equation is not balanced.

On the left-hand side, there are 3 atoms of potassium (3K), 3 atoms of bromine (3Br), and 1 atom of iron (Fe).

On the right-hand side, there is 1 atom of bromine (Br), 3 atoms of potassium (3K), and 1 atom of iron (Fe).

The number of atoms of each element should be equal on both sides of the equation. Therefore, to balance the equation, we need to adjust the coefficients of the molecules.

The balanced equation is:

3kBr + FeCl3 -> FeBr3 + 3KCl

The balanced equation has 3 atoms of potassium (3K), 3 atoms of bromine (3Br), 1 atom of iron (Fe), and 3 atoms of chlorine (3Cl) on both sides of the equation.

Answer 2

No, it’s not balanced. The Fe atoms are not balanced.

The balanced equation should be:

3KBr + FeCl3 → FeBr3 + 3KCl

In the balanced equation, both the number of Fe and Br atoms are equal on both sides of the equation.
