please answer all parts to this please, please, please
Liquid octane (C8H18) enters a steady-flow combustion chamber at 298 K and 800 kPa at a rate of 0.8 kg/min. It burned with 200 excess air that is compressed and preheated to 500 K and 800 kPa before entering the chamber. After combustion, the products enter an adiabatic turbine at 1300 K and 800 kPa and leave the turbine at 950 K and 200 kPa. Assume complete combustion and product gases to be ideal gas. The surrounding of the entire process is at 298 K. Draw a simple schematic diagram in the space below Determine (b) The heat transfer rate (in kJ/min) from the combustion chamber (c) The power output (in kW) from the adiabatic turbine (d) Exergy destroyed from the entire process (combustion turbine) The maximum possible work from the entire process Absolute entropy S (T, latin) [kUkmol Molar Enthalpy o Enthalpy (h)[kJ/kmon formation 1300 K CaH48 go4 114 -208,450 10.002 467.06 CaHa O 114 249,950 3357 360.79 I- CO2 44 -393,520 9364 17678 40,070 59.552 213.685 234.814 444 283.847 206.413 230.499 H20 (g 18 -241,820 9904 16,828 33,841 48,807 188.720 243.877 H20 0 18 285.830 1887 I- 69.95 32 8682 14,770 26.652 42,033 T 205.033 220.589 241.689 252.776 28 8669 14,581 28,501 40,170 191.502 206.630 226.389 236.831 (f) If the turbine exhaust gas were cooled down to 298 K at 100 kPa, determine how much of water vapor condensates to liquid water in kg/minExplanation / Answer
1. This statement is not true.
Kr-92 is a nobel gas(member of the zero group of the periodic table), hence its reactivity is very poor. So it is difficult to make it react with another reactant (in the reactor chimney) at room temperature. It is possible to separate Kr (incuding Kr-92 isotope) by cryogonic cooling at lower temperature where in the Kr is physiosorbed (phenomenon of adsorbtion) on the surface. The most commonly used adsorbate is activated charcoal.
2. There is no preferential concentration of I-131 over I-127 by thyroid gland. These are isotopes which differ only in the number of neutrons present in the nuclei. Chemically both these isotopes are similar (they have same number of electrons in the outer most shell) and the complexing ability with thyroxine (harmone present in thyroid gland) is similar.
