Verified answer
Respuesta:
Falso
Explicación:
No existe un compuesto llamado patrimonio y peor aún que tenga de fórmula C3H5
Para n = 3, la fórmula es:
C3H4
Como la fórmula determinada no es igual a la mencionada en el problema, la fórmula C3H5 no responde a la fórmula CnH2n-2. Por tanto, es falso.
Respuesta:
A. C2H5 y 58,1 g
Mm FE
C: 2 x 12 = 24 g/mol
H: 5 x 1 = 5 g/mol
````````````````````````````
Mm = 29 g/mol
n = Mm FM
````````````
Mm FE
n = 58.1 g/mol / 29 g/mol = 2
n = 2
FM: (C2H5)n = (C2H5)₂ = C₄H₁₀ RESPUESTA: C
B: CH2O y 60 g
Mm FE
C: 1 x 12 = 12 g/mol
H: 2 x 1 = 2 g/mol
O: 1 x 16 = 16 g/mol
````````````````````````````
Mm = 30 g/mol
n = Mm FM
````````````
Mm FE
n = 60 g/mol / 30 g/mol = 2
n = 2
FM: (CH₂O)n = (CH2O)₂ = C₂H₄O₂ RESPUESTA: C
C. KClO3 y 122.5 g
Mm FE
K: 1 x 39 = 39 g/mol
Cl: 1 x 35.5 = 35.5 g/mol
O: 3 x 16 = 48 g/mol
````````````````````````````
Mm = 122.5 g/mol
n = Mm FM
````````````
Mm FE
n = 122.5 g/mol / 122.5 g/mol = 1
n = 1
FM: (KClO3)n = (KClO3)₁ = KClO3 RESPUESTA: A
