The coefficient of reactants $\rm CuCl_2$ and $\rm H_2S$ has been 1, while the coefficient of product CuS has been 1, and HCl has been 2.

The balanced equation has been given as the reaction in which the atoms of each elements in the product and the reactant side has been equal.

The reaction has been given as:

$\rm CuCl_2\;+\;H_2S\;\rightarrow\;CuS\;+\;HCl$

In the reaction, the number of atoms of elements have been:

Cu = reactant = 1

Product = 1

Cl = reactant = 2

Product = 1

H = reactant = 2

Product = 1

Sulfur = reactant = 1

Product = 1

The atoms of H and Cl has been 2 at the reactant side, and 1 at the product side. The reaction has been balanced by adding coefficient 2 to HCl.

Thus, the balanced reaction has been:

$\rm CuCl_2\;+\;H_2S\;\rightarrow\;CuS\;+\;2\;HCl$

The coefficient of reactants $\rm CuCl_2$ and $\rm H_2S$ has been 1, while the coefficient of product CuS has been 1, and HCl has been 2.

The answer to your question is 1, 1 , 1 , 2

Explanation:

Reaction

CuCl₂ + H₂S ⇒ CuS + HCl

Reactants Elements Reactants

1 Copper 1

2 Chlorine 1

2 Hydrogen 1

1 Sulfur 1

This reaction is unbalanced

CuCl₂ + H₂S ⇒ CuS + 2HCl

Reactants Elements Reactants

1 Copper 1

2 Chlorine 2

2 Hydrogen 2

1 Sulfur 1

Just add 2 to hydrochloric acid, now the reaction is balanced.
