Question

balance the following equation:
_fes + _hcl→_fecl₂+ _h₂s
when the equation is properly balanced, the correct coefficients are, respectively

Explanation:

Step1: Balance Fe and S

Fe and S are already balanced as there is 1 Fe and 1 S on both sides.

Step2: Balance Cl and H

On the right - hand side, there are 2 Cl in \(FeCl_{2}\) and 2 H in \(H_{2}S\). So, we need 2 HCl on the left - hand side.

Answer:

1, 2, 1, 1
