A255ml round-bottom flask is weighed and found to have a mass of 114.85g. a few ml of an easily vaporized liquid are added to the flask and the flask is immersed in a boiling water bath. all of the liquid vaporizes at the boiling temperature of water, filling the flask with vapor. when all of the liquid has vaporized, the flask is removed from the bath, cooled, dried and reweighed. the new mass of the flask and the condensed vapor is 115.23g. which of the following compounds could the liquid be? (assume the ambient pressure is 1.0atm)a. c2h5ohb. c4h10c. c2h6d. c4h9ohe. c3h7oh

One of the hopes for solving the world's energy problem is to make use of the fusion reaction 21h +31h --> 42he + 10n + energy how much energy is released when 1 mol of deuterium is fused with 1 mol of tritium according to the above reaction? the masses of the atoms and the neutrons are as follows: 21h = 2.0140 amu 31h = 3.01605 amu 42he = 4.002603 amu 10n = 1.008665 amu. the speed of light is 2.9979 x 108 m/s.
