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:
An ionic compound whose aqueous solution conducts an electric current is called a(n) electrolyte
Explanation:
Electrolytes are substances that contain anions and cations and is therefore able to conduct the electric current.
For example: NaCl
NaCl → Na⁺ + Cl⁻
Answer:
107,200J or 25.62 kcal
Explanation:
The latent heat of water is 4.2J/g °C so the energy needed to increase the tempearture from 80 °C to 100°C will be:
40g * 4.2J/g °C * (100-80°C )= 3,360J
The heat of vaporization of water is 2260J/g so the energy need to change water from liquid to gas is:
40g * 2260J/g = 90,400J
The heat needed to increase steam temperature should be same as latent heat of water, 4.2J/g °C . So, the energy needed to increase temeprature from 100 to 180 will be:
40g * 4.2J/g °C * (180-100°C )= 13,440J
The total energy needed will be: 3,360J + 90,400J +13,440J= 107,200J
Answer : The mass of 
produced will be, 49.32 Kg
Explanation : Given,
Mass of 
= 26.1 Kg = 26100 g
Molar mass of = 26.98 g/mole
Molar mass of = 32 g/mole
First we have to calculate the moles of .
Now we have to calculate the moles of .
The balanced chemical reaction is,
From the balanced reaction we conclude that
As, 2 moles of react to give 1 mole of
So, 967.38 moles of react to give 
moles of
Now we have to calculate the mass of .
Therefore, the mass of produced will be, 49.32 Kg
