–Internal Energy <p>The internal energy of a gas is given by the equation U (J/mol) = 150 T + 0.1T^2 (T in C). The initial (or entering) conditions are 9 bar, 0 C, and a volume of 1 cubic meter. What is Q (kJ) for a final state at 294 C and a volume of […]
In trans-1,2-dibenzoylethylene In trans-1,2-dibenzoylethylene, even though the conjugated C=O group frequency coincides directly with the expected C=C stretching frequency, we would not have expected to observe the latter stretching mode in the infrared spectrum. Why?
Suppose 1.00 g of water vaporizes isobarically at atmospheric pressure (1.013 x 10 5 Pa). Its… Suppose 1.00 g of water vaporizes isobarically at atmospheric pressure (1.013 x 105 Pa). Its volume in the liquid state is Vi = Vliquid = 1.00 cm3, and its volume in the vapor state is Vf = Vvapor = […]
