Balance chemical equation CuS(s)+HCl(aq)=CuCl2(aq)+ H2S(g)

CuS(s) + 2HCl(aq) —> CuCl2(aq) + H2S(g)

Explanation:

CuS(s) + HCl(aq) —> CuCl2(aq) + H2S(g)

The above equation can be balance by by doing the following:

CuS(s) + HCl(aq) —> CuCl2(aq) + H2S(g)

There are 2 atoms of H on the right side and 1 atom on the left side. It can be balance by putting 2 in front of HCl as shown below:

CuS(s) + 2HCl(aq) —> CuCl2(aq) + H2S(g)

Now the equation is balanced since the number of atoms present in the elements are the same on both side of the equation i.e

Reactant:

Cu = 1

S = 1

H = 2

Cl = 2

Product:

Cu = 1

S = 1

H = 2

Cl = 2

Therefore, the balanced equation is:

CuS(s) + 2HCl(aq) —> CuCl2(aq) + H2S(g)
