6. ¿Qué masa y cantidad de sulfuro de cobre se obtiene al hacer reaccionar 64g de azufre con la cantidad adecuada de cobre? 2Cu+5=
bueno ami me queda así la respuesta solo quiero que me ayuden a ver si esta bien.
2Cu +5↔Cus S.P=64*2
Cus=64*2= 128 S.D=Cu2S
S= → 32
-----------
160grCu2S
160 gr Cu2S → 64grS
X → 32grS
8grCu2S

Cu + S → CuS
Mm Cu = 63.54 g/mol
CuS = 95.61 g/mol
S = 32.06 g/mol
1. calcular gramos de CuS
g Cu2S = 64 g S x 1 mol S x 1 mol CuS x 95.16 g CuS
`````````````` `````````````````` `````````````````````
32.06 g S 1 mol S 1 mol CuS
g CuS = 189.96
2. Calcular moles de CuS
mol CuS = 189.96 g CuS x 1 mol CuS
````````````````````
95.61 g CuS
mol CuS = 1.986
