Nylon undergoes depolymerization when heated in aqueous acid. Propose a reaction mechanism that accounts for this fact, using curved arrows to symbolize the flow of electrons.
Note: The nylon 6,6 was made out adipoyl chloride and hexamethylenediamine (Also 10 drops of sodium hydroxide was used to initiate reaction)
In a beaker, I mix 50 ml of 3 M HCl with 100 ml distilled water. Both fluids are at 25 C initially. (Cp mix =. 0.985 cal/g-C) a. what is the final T.
A flask contains 0.110 mol of liquid bromine, Br2. Determine the number of bromine molecules present in the flask.
A 122 piece of metal is heated to 285 and dropped into 84.0 of water at 26. If the final temperature of the water and metal is 58.3, what is the specific heat of the metal.
if you have 430.00 ml of water at 25.00 degrees celcius.and add 100 ml of water at 95.00 degrees celcius, what is the final temperature of the mixture?
Consider the combustion of ammonia: 4 NH3(g) + 3 O2(g) 2 N2(g) + 6 H2O(g). If N2 is produced at the rate of 0.63 mol/s, what is the rate of consumption of NH3?
A 0.5485 g solid mixture have only ferrous chloride hexahydrate and ferrous ammonium sulfate hexahydrate. dissolved in 1M sulphuric acid get oxidized to Fe3+ with hydrogen peroxide, and get precipitated with cupferron.
The solubility of the K3[Fe(C2O4)3].3H2O product at 00C is 4.7 g per 100 g water. Given this, calculate the maximum percent yield of product for your own reactant quantities.
What is the pH of a solution made by dissolving 46g of acetic acid in enough water to make 700 ml of solution
A sample of oxygen occupies 10.0 L at 4.00 atm pressure. At what temperature will the pressure equal 3.00 atm if the final volume is 8.00 L.
A gaseous system undergoes a change in temperature and volume. What is the entropy change for a particle in this system if the final number of microstates is 0.407 times
Explain how chymotrypsin combine different modes of catalysis( acid/base and covalent chemistry; proximity effects and transition state binding/stabalization) to acheive the rate enhancement observed for enzyme catalyzed reactions.
