Answer 1

Answer:

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.

Answer 2

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.
