A United Nations toxicologist studying the properties of mustard gas, S(CH2CH2Cl)2, a blistering agent used in warfare, prepares a mixture of 0.675 M SCl2 and 0.973 M C2H4 and allows it to react at room temperature (20.0°C ). SCl2(g) + 2 C2H4(g) S(CH2CH2Cl)2(g) At equilibrium, [S(CH2CH2Cl)2] = 0.350 M. Calculate Kp.
Deuterium oxide (D2O, where D is deuterium, the hydrogen-2 isotope) has an ion-product constant, Kw, of 8.9 x 10^-16 at 20 *C (degrees Celsius). Calculate [D+] and [OD-] for pure (neutral) D2O at this temperature.
