Benzene as well as toluene mix to form a liquid solution @20degrees C and solution behaves as ideal solution. Explain the Vapor pressure of pure benzene is 74.7Torr and that for pure toluene is 23.3Torr. Explain the mole fraction of each in the VAPOR phase if there are 3.12moles of benzene as well as 1.25 moles of toluene
A nugget of pure gold of 4.90 grams absorbed heat of 270 Joules. determine the final temperature of the Au if the initial temperature = 22.0°C? specific heat of Au =0.129 J/(g·°C).
Give equations to show how sulfuric acid can convert 4-methyl cyclohexene into a mixture of four isomeric c7H12 compounds(including starting material). Predict the relative amounts of each isomer.
What factors can effect retention time. What factors might I change and how to increase the retention time of a polar compound
degree celsius in a heat exhanger by 54430 kg/h of hot gas flowing counterflow and entering at 427 degree celsius. (Cpm=1.005 kj/kg*K). The overall Uo=69.1 W/m^2*K. Calculate the exit gas temperature and the heat transfer area.
A 0.2527-g sample of a mixture of Mg(OH)2 and Al(OH)3 was treated with 50.00 mL of 0.225 mol L 1 HCl(aq). The resulting solution required 13.73 mL of 0.176 mol L 1 NaOH(aq) to neutralize the excess, unreacted HCl.
A clinic took temperature readings of 250 flu patients over a weekend and discovered the temperature distribution to be Gaussian, with a mean of 101.00°F
You are going to administer 201 / 81 Ti to a patient in preparation for a stress test in a patient with possible coronary artery disease. The half-life of 201 / 81 Ti is 73.0 hours.
Begin from the Maxwell distribution of speeds as well as derive an expression for the most probable speed of a gas of molecules at temperature T.
The gas inside a flexible container (e.g., a balloon) is allowed to expand against a constant external pressure of 1.3 bar until the volume increases from 2.7 L to 10.5 L. Calculate the amount of work done on the system.
Using the following data for the specific volume of mercury, estimate the error in a temperature reading from a mercury-in-glass thermometer when the actual temperature is 600C
