1. Nuclear Reactions (i) In class we went through the U-235 fission reaction. There is another nuclear fission reaction that can be used in a reactor and that is the plutonium-239 reaction. Write down what that reaction is for the fission of a plutonium if the daughter products are 134Xe, 143Zr and 3 neutrons. 23Pu= 239.0521u u= 1.6605x10-27 kg e=...

9. In this laboratory experiment, you use excess carboxylic acid (2.4 equivalents). Therefore, when the reaction is complete, you will have some carboxylic acid along with your ester as the product. Answer the following questions: (a) How was this excess carboxylic acid removed from your ester product? To answer this question, answer the two parts below. (i) Draw the reaction...

4 What is the molar mass of a nonelectrolyte if a solution containing 45.0 g of the nonelectrolyte in 75.0 g of benzene boils at 90.2°C? For a system at equilibrium, which of the following are true? 5- a. The rate of the reaction is zero. b. Th c. The value for th e concentrations of reactants and products are...

When o-bromoanisole is treated with NaNH2 in NH3 (I), a reaction proceeding via a benzyne intermediate, what two isomeric products are possible? (Check two products). o-methoxyaniline m-methoxyaniline p-methoxyaniline In practice, only one isomer is formed. Which one is it? o-methoxyaniline m-methoxyaniline p-methoxyaniline Why is this product favored? (Select the major factor). The methoxy group is too bulky and causes a...

Page - 3 - of 9 ЗА) To get an anti - 1, 2 diol configuration, you have to go through an epoxide ring-opening reaction. In class, we showed this reaction happening in acidic or in basic conditions with a different mechanism. Below, DRAW a good arrow-pushing mechanism, showing all steps, for the epoxide ring- opening under both conditions, separately....
