A certain ideal gas has molar heat capacity at constant volume Cv. A sample of this gas initially occupies a volume Vo at pressure Po and absolute temperate To. The gas expands isobarically to a volume 2Vo then expands further adiabaticallly to a final volume of 4Vo
(a) Compute the total work done by the gas for this sequence ofprocesses.
(b) Find the final temperatur of the gas.
(c) Find theabsolute value |Q| of the total heat flow into or out or the gasfor this sequence of processes, and state the direction of heatflow.
Rank the following compounds in order of their decreasing solubility in water (the one having the greatest solubility would be first)
Iron (III) oxide(s) is heated in excess carbon monoxide(g) to form iron(s) and carbon dioxide(g). If the percent yield of iron was 83.0% and the actual yield was 9.87 g, how much iron (iii) oxide was used?
A weak base B has a dissociation constant Kb = 1.0 X 10-7. For a 0.30 M solution of B in water,
At equilibrium the total pressure and density of the gaseous mixture were 1.80atm and 1.60g L-1, respectively. Calculate Kc and Kp.
Calculate ?E, q, and w if 8.00 moles of CO2 (g) reacts with excess nitrogen gas according to the following reaction at 25°C and 1.00 atm: 4CO2(g) + N2(g)?4CO(g) + 2NO2(g)
Benzene is a organic solvent with the formula, The volume occupied by 1 micromole of liquid benzene and the volume occupied by 1 megamole of benzene as a vapor at STP (assume an ideal gas)
For the copper zinc cell the potential at 25 degrees C is 1.10 volts. The reaction is: Cu++ (aq) + Zn(s) = Zn ++ (aq) + Cu(s) Calculate the equilibrium constant for this reaction (a wire is connected and electrons flow between the electrodes)
Calculate the work in kilojoules done during a synthesis of ammonia in which the volume contracts from 7.6 L to 4.6 Lat a constant external pressure of 41atm.
When steam condenses to liquid water, 2.26 kJ of heat is released per gram. The heat from 168 g of steam is used to heat a room containing 6.44*104 g of air (20ft*12ft*8ft). The specific heat of the at normal pressure is 1.015 J/(g°C).
Camphor is mixed with methanol, then sodium borohydride is added. Then boil, add mixture to ice and stir.
For molecules containing a single stereocenter located at the carbon bearing the leaving group, SN2 reactions proceed with the inversion of configuration and Sn1 reactions proceed with retention of configuration
It has a diameter of 13.46 cm. On the other hand, spent uranium (from processing which removes the commercially important rare isotope) has a specific gravity of 19.05. How many pounds would a uranium cannonball of the same dimensions as the iron ..
