Calculate the work in Joules when 2.5 mols of water vaporizes at 1 atmosphere pressure and 25 degrees C. The work is done in pushing back the atmosphere. Assume that the change in volume of the liquid water is negligible compared to that of the vapor.
a. 1.33 kiloJoules
b. 17.03 kiloJoules
c. 5.57 kiloJoules
d. 7.24 kiloJoules
e. 6.19 kiloJoules
Give Structures- Indentify unknown organic liquids, An unknown organic liquid, A, was found to burn with yellow, sooty flame and give a positive Lucas test (about 5 min). Upon treatment with sodium dichromate-sulfuric acid solution it produced Comp..
The energy levels of hydrogenlike one-electron ions of atomic number Z differ from those of hydrogen by a factor of Z^2. Predict the wavelength of the transition
Calculate the mole fraction of ethylene glycol in the solution.
The reaction previously done was just having trans-cinnamic acid reacted with Br2 forming all the isomers with the double bond being broken and Br put into place.
temperature of 15.4°C is placed flat on a sheet of iron weighing 21.3 g and at a temperature of 46.6°C. What is the final temperature of the combined metals?
A solution of hydrochloric acid has a concentration of 12.8 mol/L. However, a chemistry professor needs HCl(aq) with a concentration of 0.100 mol/L for an experiment with his students.
Method for Trapping a Gas, The decomposition of 3-sulfolene to form 1,3-butadiene generates 1 mole of sulfur dioxide gas per mole of 1,3-butadiene. Substantial quantities of SO2 would be generated if this decomposition were carried out on a large ..
A gas sample has an original volume of 800 ml when collected at 710 mm and 30°C. What will be the volume of the gas sample if the pressure increases to 780 mm and the temperature increases to 35°C?
3.10 percent of the Br2 undergoes dissociation. Calculate the equilibrium constant Kc for the reaction.
The attractive force between neighboring dipoles. the force that arises because of the large differences in electronegativities in the N-H bonds
Please consider the reaction of 0.22M 2-iodopropane with tetramethylammonium fluoride (TMAF) in DMSO to give propylene. The reaction rate in the presence of 0.1M TMAF is 0.002 M/s, but it is 0.0058 M/s in the presence of 1.2M TMAF.
Calculate the pressure of 4 g of nitrogen gas in a 1 L container at 20.0 ?C.
