A gas mixture contains 4.6 g ofN2, 8.8g of H2 and 16.6g of CH4. What is the mole fraction of H2 in the mixture?
A 20.00mL sample of H3Y was titrated with 0.1000 M NaOH. The first equivalence point was reached after the addition of 14.98mL of base. The second equivalence point was reached after the addition of 30.03mL.
While shutdown, the core accidentally went critical and the reactor pressure vessel rose in temperature and was hot for two hours, but all instrumentation has failed and no one is sure what the temperature was.
At 298, 1 atm, the heat produced by the reaction of 4.00mol of NO with molecular oxygen heats 1.07L liquid water from 298k to 348k. Calculate enthalpy for the reaction 2NO + O2 -> NO2, at 298k. Assume constant pressure and no heat lost.
