Nylon 6,6 may be formed by means of a condensation polymerization reaction in which hexamethylene diamine [NH2-(CH2)6-NH2] and a

dipic acid react with one another with the formation of water as a byproduct. What masses of (a) hexamethylene diamine and (b) adipic acid are necessary to yield 36 kg of completely linear nylon 6,6? This polymerization reaction occurs according to the following equation:

Answer:

Explanation:

molecular mass of nylon ( C₁₂H₂₂N₂O₂ ) = 226 gm

Molecular mass of adipic acid = 146 gm

Molecular mass of hexamethylenediamine = 116 gm

no of moles of nylon = 36000 / 226

= 159.29

one mole of nylon requires one mole of hexamethylenediamine and one

mole of adipic acid .

159.29 mole of nylon requires 159.29 mole of hexamethylenediamine and 159.29 mole of adipic acid

159.29 mole of hexamethylenediamine

= 159.29 x 116 gm

= 18.48 kg of hexamethylenediamine

159.29 mole of adipic acid = 159.29 x 146 gm

= 23.26 kg .

18.48 kg of hexamethylenediamine and 23.26 kg of adipic acid will be required.

what might cause the goldfish population to drop if the temperature moves out of its normal range? Name three things
Slav-nsk [51]

Answer:

Appearing disoriented, such as swimming upside down.

Leaving food uneaten.

White spots on fins or body.

Discolored gills.

Explanation:

Gold Fish are unable to regulate their body temperature, so they are influenced by the temperature around them. If the water is warm, gold fish metabolism accelerates, feeding and respiration increases, and there is a general increase in movement. If the water is cooler, fish become lethargic and tend to be inactive.

a rectangular piece of aluminum foil measures 13.72 cm x 8.63 cm and has a mass of 3.1 g. Find how thick it is
Leona [35]

The two dimensions of aluminum foil are given 13.72 cm and 8.63 cm respectively with mass  3.1 g.

The density of aluminum is 2.7 g/cm^{3}. It is defined as mass per unit volume thus, volume of aluminum can be calculated as follows:

V=\frac{m}{d}

Putting the values.

V=\frac{3.1 g}{2.7 g/cm^{3}}=1.148 cm^{3}

The volume of cuboid is l\times b\times h, the length and breadth are given, height can be calculated as follows;

h=\frac{V}{l\times b}

Putting the values,

h=\frac{1.148 cm^{3}}{(13.72 cm)(8.63 cm)}=0.009695 cm

Or, approximately 9.7\times 10^{-3}cm

Therefore, thickness of aluminum foil is 9.7\times 10^{-3}cm
