When 1,5-dibromopentane reacts with ammonia, among several products
isolated is a water-soluble compound A that rapidly gives a
precipitate of AgBr with acidic AgNO3 solution. Compound A is
unchanged when treated with dilute base, but treatment of A with
concentrated NaOH and heat gives a new compound B (C10H19N) that
decolorizes Br2 in CCl4. Compound B is identical to the product
obtained from the reaction sequence shown below. Identify A and
B.

When a bullet leaves a rifle it has a lot of kinetic energy, most of which gets lost as heat. Imagine that a 9.8kg lead bullet is fired into a ort upon which the actual target was sitting . The bullets initial speed is 760 m/s, and as it comes to rest half of its kinetic energy goes into heating the bullet. How much does the bullets temperature increase
