Answer:
r= 0.9949 (For 15,000)
r=0.995 (For 19,000)
Explanation:
We know that
Molecular weight of hexamethylene diamine = 116.21 g/mol
Molecular weight of adipic acid = 146.14 g/mol
Molecular weight of water = 18.016 g/mol
As we know that when adipic acid and hexamethylene diamine react then nylon 6, 6 comes out as the final product and release 2 molecule of water.
So
So
Mo= 226.32/2 =113.16 g/mol
Given that
Mn= 15,000 g/mol
So
15,000 = Xn x 113.16
Xn = 132.55
Now by using Carothers equation we know that
By calculating we get
r= 0.9949
For 19,000
19,000 = Xn x 113.16
Xn = 167.99
By calculating in same process given above we get
r=0.995
Answer:
No reaction is observed
Explanation:
The benzene ring is aromatic. Being an aromatic ring, the benzene ring is remarkably stable to all reactions that destroy the aromatic ring.
Alkenes are oxidized to alkanols in the presence of KMnO4 but this reaction does not occur with benzene. However, substituted benzenes having hydrogen atoms attached to the substituent carbon atom can be oxidized to the corresponding carboxylic acid.
Answer:
Theoretical yield for Si = 2586.55*28.09= 72.7 Kg
Percentage yield is =2356.71/2586.55=91.11%
Explanation:
So the chemical equation for this reaction would be SiO2 + 2C = Si + CO
so n(SiO2)=m(SiO2)/M(SiO2)=155400/60.08=2586.55 mol
n(C)=m(C)/M(C)=77400/12.01=6444.63 mol
So Carbon is in exes.
n(Si)=m(Si)/M(Si)=66200/28.09= 2356.71 mol
Theoretical yield for Si = 2586.55*28.09= 72.7 Kg
Percentage yield is =2356.71/2586.55=91.11%
