Consider 1:1 stoichiometric polymerization of 1,4-diaminobutane with sebacoyl chloride. (a) Write down a balanced chemical equation for the polymerization. (b) Name the polymer formed by this polymerization. (c) Using the Carothers equation, calculate the extent of reaction required to produce this polymer with a number-average molar mass M – n = 25.0 kg mol−1. You should neglect the effects of end groups on molar mass. (d) Explain briefly the consequences of including 1,1,4,4-tetraminobutane in the polymerization with an exact stoichiometric ratio of 2:1:4 of 1,4-diaminobutane to 1,1,4,4-tetraminobutane to sebacoyl chloride. 3.8 A polycondensation reaction takes place between 1.

Liquid ammonia is produced at high temperatures and under great pressure in a tank by passing a mixture of nitrogen gas and hydrogen gas over an iron catalyst. the reaction is represented by the following equation. n2(g) + 3h2(g) → 2nh3(g) changing all but one experimental condition will affect the amount of ammonia produced. that condition is a) increasing the concentration of both reactants b) changing the temperature within the tank c) decreasing the pressure within the tank. d) increasing only the amount of nitrogen present.
