Depict the products of the subsequent reaction the acid-catalyzed dehydration of 3,4-dimethyl-3-hexanol to 3,4-dimethyl-3-hexene.
A nonelectrolyte solution adsorbs on an electrically neutral solid through a liquid. Two surfaces of this type are brought close to one another in the liquid such that they interact.
Present your strategy and detailed mechanism how you prepare2-chloro-3-nitrotolune starting with benzene. Demonstrate the sequequence of steps and appropriate reagents providing detailed mechanism of each process
Some wastewater has a BOD5 of 150 mg/L at 20 degrees Centigrade. The reaction rate k at that temperature has been determined to be 0.23/day.
A catalyst increases the overall rate of reaction by lowering the activation energy, Ea, for A) both the forward reaction and the reverse reaction. B) neither the forward reaction nor the reverse reaction.
A 25.0 mL sample of unknown hydrochloric acid solution is titrated with 0.100 M NaOH. The equivalence point was reached after the addition of 23.5 mL NaOH. Find the concentration of the unknown HCl(aq).
Explain how the formation of a soap ‘micelle' helps remove dirt and oil in an aqueous environment.
Assuming that a neutron star has the same density as a neutron, calculate the mass (in kg) of a small piece of a neutron star the size of a spherical pebble with a radius of 0.20 mm.
Describe and explain the possible effect on your results of the following experimental errors or variations. In each case specify the component(s) whose percentage(s) would be too high or too low.
Given that delta r H = 40.67 kj/mol for vaporization of H20 at 100 degrees celcius, what is delta S tot for vaporization of 1 mol of water at 1 bar pressure at 125 degrees celcius? Is this process spontaneous?
