Question

Question 3: There are several technological applications for the transuranium elements (Z > 92). An important one is in smoke detectors, which can use the decay of a tiny amount of americium-241 to neptunium-237. What subatomic particle is emitted from that decay process? Please explain your answer.

Question 4:   Nylon 88 is made from the monomers H2N(CH2)8NH2 and HOOC(CH2)6COOH. So, would you characterize nylon 88 as rather an addition or a condensation polymer?   Please explain your answer.

Explanation / Answer

3 - From Americium-241 to Neptunium-237, we have a mass difference of 4 units. That means the particle emitted has a mass of 4.

Alpha-particle matches with this and so an alpha partile is lost in the decay procees of americium-241 to neptunium-237.

4 - Nylon 88 is made from diamine H2N(CH2)8NH2 and a dicarboxylic acid HOOC(CH2)6COOH via a condesation polymerisation reaction strategy wherein, a water moelcules is lost from each end by the condensation reaction of the two monomers. An amide lnkage -CO-NH- bond is formed by the condensation reaction after the loss of a H2O molecule.
