Nylons are strong sythetic fibers commonly used to make clothing and other goods. One of the most common nylons, Nylon 66, is ma
de by the condensation reaction between adipic acid and hexamethylenediamine (hexane-1,6-diamine). Modify the monomers below to create one repeat unit of the polymer.What other, small molecule is produced in this reaction? Give the formula of the compound (not the name).
1 answer:
Answer:
The small molecule produced in this condensation reaction is water.
Formula of the compound is given by
Explanation:
Nylon is a poly amide which is formed by the condensation reaction between adipic acid and hexamethylenediamine.
A reaction is called a condensation reaction when it involves removal of small molecules like water to form product.
In this condensation reaction a molecule of water is removed between the monomers to form a repeating unit of polymer. This process is clearly explained by the figure below.
We can see that the -OH group from the acid and -H atom from amine is removed to form a -CONH- group known as amide group.In effect a water molecule is removed in the formation of Nylon-6,6.
Since the monomers are connected by an amide group the polymer thus formed is a poly amide .We can see from the attachment that the formula of the polymer formed is .

Answer: 32.94 g
Explanation: It's stoichiometry problem so balanced equation is required. The balanced equation is given below:
From the balanced equation, krypton and chlorine react in 1:2 mol ratio. We will calculate the moles of each reactant gas using ideal gas law equation(PV = nRT) and then using mol ratio the limiting reactant is figured out that helps to calculate the amount of the product formed.
for Krypton, P = 0.500 atm and for chlorine, P = 1.50 atm
V = 15.0 L
T = 350.8 + 273 = 623.8 K
For krypton,
n = 0.146 moles
for chlorine,
n = 0.439
From the mole ratio, 1 mol of krypton reacts with 2 moles of chlorine. So 0.146 moles of krypton will react with 2 x 0.146 = 0.292 moles of chlorine.
Since 0.439 moles of chlorine are available, it is present in excess and hence the limiting reactant is krypton.
So, the amount of product formed is calculated from moles of krypton.
Molar mass of krypton tetrachloride is 225.61 gram per mol.
There is 1:1 mol ratio between krypton and krypton tetrachloride.
= 32.94 g of
So, 32.94 g of the product will form.
