A steam power plant operates on an ideal Rankine cycle with two stages of reheat and has a net power output of 120 MW. Steam enters all three stages of the turbine at 500°C. The maximum pressure in the cycle is 15 MPa, and the minimum pressure is 5 kPa. Steam is reheated at 5 MPa the first time and at 1 MPa the second time.
Show the cycle on a T-s diagram with respect to saturation lines, and determine (a) the thermal efficiency of the cycle and (b) the mass flow rate of the steam.
Molecular iodine, I2(g), dissociates into iodine atoms at 625 K with a first-order rate constant of 0.271 s^-1. If you start with 7.0×10?2 M I2 at this temperature
In an acidic solution (with an excess of iodate), the titration of a 25 mL sample of potassium iodide required 26.51 mL of 0.0949M sodium thiosulfate titrant.
Concentrated ammonia is added to an aqueous solution of copper(II) sulfate. Initially, a white precipitate forms. As more ammonia is added, the precipitate dissolves and the solution becomes a deep bluish-purple
