It took 25.06 0.05 mL of a sodium hydroxide solution to titrate a 0.4016-g sample of KHP (see Exercise 65). Calculate the concentration and uncertainty in the concentration of the sodium hydroxide solution. (See Appendix 1.5.) Neglect any uncertainty in the mass. Explain how you arrived at your answer.
Determine the minimum electric potential difference (in volts) that must be applied to accelerate an a-particle so that on interaction with a hydrogen atom, a ground state electron will be excited to n = 6
derive the time constant for transfer of a metabolite from a particular cell to a neighboring cell. Assume that these are two epithelial cells whose geometry can be approximated as a box and that the two adjacent boxes are connected with transfer ..
What is the mass of the volume of combined fuel product? What is the total volume of combined fuel allowed on the truck? What is the volume of E100 allowed on the truck? What is the volume of E85 allowed on the truck?
A small atomic bomb releases energy equivalent to the detonation of 20,000 tons of TNT; a ton of TNT releases 4x10^9 J of energy when exploded. Using 2x10^13 J/mol as the energy released by fission of 235U, approximately what mass of 235U undergoe..
Explain in detail the working of the instrument. Description should include neat diagram, principle of working and the source of literature.
The ship must unload 1000 metric tons within 5 hours to avoid demurrage charges. Estimate the power required by the pump. Take the pump efficiency as 70%. Physical properties of toluene: density 874 kg/m3, viscosity 0.62 mNm-2 s.
The 50-turn coil in the configuration of Figure P12.1.3 is rotated at a constant speed of 300 r/min. The axis of rotation is perpendicular to a uniform magnetic flux density of 0.1 T. The loop has width w = 10 cm and length l = 1 m
Explain why the value of the normalized ratio (R) in a pulse oximeter is independent of the volume of arterial blood entering the tissue during systole.
For parts (a), (c), (d), (f), and (h) of Problem 10.20, determine the approximate percentages of the microconstituents that form. (a) Rapidly cool to 250(C (480(F), hold for 103 s, then quench to room temperature.
What is the required flow rate of cooling water to the exchanger between the wasteheat boiler and the absorber and how much heat must be removed by the two heat exchangers cooling the recycled absorber liquid? Why is there a need to remove this heat?
A turbine is fitted in the pipeline to recover the excess energy that is available, over that required to transfer the liquid from one vessel to the other. Estimate the power that can be taken from the turbine, when the liquid transfer rate is 500..
Machining of composites can be classified as conventional machining and non-traditional machining. Among each category, there are many processes. Describe each of those processes, by giving the brief definition of the process, listing the machine..
