Find vapor pressure and density of liquid water at room temperature; state your source. Calculate the new vapor pressure of water at the same temperature when 740 torr of dry air is added to the container in which the liquid water is held. What is the percent change?
Please draw a detailed arrow-pushing mechanism for the addition of HBr to trans-2-butene. Also draw a potential energy diagram for this reaction.
How can we explain the ability of an electron to cross through a node, such as the nucleus, to occupy the region within an entire orbital?
Gibbs Free Energy and Equilibrium The reaction SO2(g)+2H2S(g)?3S(s)+2H2O(g) is the basis of a suggested method for removal of SO2 from power-plant stack gases
Find out the required pressure to compress 180 liters of N at 1.0 atm into a tank whose volume is 34 liters.
The metal hydride LiH has a density of 0.77 g/cm3 . The edge of the unit cell is 4.086 . If it is assumed that the H ions define the lattice points, does the compound have a face-centered cubic or a simple cubic unit cell?
A gaseous reaction occurs at a constant pressure of 45.0 and releases 61.0 of heat. Before the reaction, the volume of the system was 9.00 . After the reaction, the volume of the system was 3.00 .
Calculate the average speed of a gas that has a molar mass of 2.08 × 10-2 kg /?mol at a temperature of 22°C. The value for the gas constant, R, is 8.314 J /?mol K.
a solution is prepared by dissolving 4.21 g of a nonelectrolyte in 50.0 g of water. If the boiling point increases by 0.203 C what is the molar mass of the solute? The boiling point elevation constant for water is 0.512 C/.
