If a breakdown of the thermal insulation around the turbine allows a heat loss of 60 kJ per kg of stream, and the exiting steam is at 150oC and 0.3 MPa, what will be the power developed by the turbine if the inlet steam conditions and flow rate ar..
How much 1.0 M NaOH must be added to a 100 ml of 10 mM H3PO4 to raise the pH of the solution to 7.0? B) If 2 volumes of 2.0 M Na2HPO4 are added to 1 volume of 0.1 M H3PO4, what is the pH of the resulting phosphate buffer?
Calculate the pH of the solution made by adding 0.50 mol of HOBr and 0.30 mol of KOBr to 1.00 L of water.
The tricky part of this multi step synthesis is the isolation of the neutral p-aminobenzoic acid in the second step. Why is isolation so difficult
efficiency for conversion of potential to electrical energy, and 8% loss of the resulting power in transmission, what is the mass flowrate of water required to power a 200-watt light bulb?
nitrobenzenesulfonic acid starting from benzene and using any needed organic/inorganic reagents.
For such systems, it is often observed that the ratio of the vapor pressures of the pure species is nearly constant over a considerable temperature range. Let this ratio be r, and determine the range of values of A, expressed as a function of r, f..
The sample is placed in a drying dish (weight = 0.5000 g before the sample is added), and then placed in an oven at 104°C until all the moisture is evaporated
