Question

Fe2S+ HCl----> FeCl2+ H2S
por favor alguien que me ayude a balancear esta ecuacion y A SABER SUS PESOS ATOMICOS.

Answer 1

FeS + 2 HCl → FeCl2 + H2S

Mm FeS
Fe: 1 x 55.8 = 55.8 g/mol
 S:  1 x 32 = 32 g/mol
````````````````````````````````
           Mm = 87.8 g/mol

HCl

  H: 1 x 1 =1 g/moo
Cl:1 x 35.4 = 35.5 g/mol
````````````````````````````````````
           Mm = 36.5 g/mol


FeCl2

Fe: 1 x 55.8 = 55.8 g/mol
Cl: 2 x 35.4 = 70.8 g/mol
````````````````````````````````````
          Mm = 126.6 g/mol

H2S

H: 2 x 1 = 2 g/mol
S:1 x 32 = 32 g/mol
````````````````````````````
       Mm = 34 g/mol
