How much heat has to be removed from 3kg of boiling water (with mass fractions: 30% of liquid h2o and 70% of gaseous h2o) at constant pressure P=25 bar to make it a "compressed liquid" at temperature 140C. Assume that the specific heat of the substance at P=25 bar is temperature independent and equal to c_p=4.20 kJ/kg*K. Sketch the P-v and T-s diagrams of the cycle.
A water treatment plant has a flowrate of 40,000 m3/d. If the overflow rate is 25 m3/d/m2, determine the following:

A chemistry student needs 80.0mL of acetone for an experiment. By consulting the CRC Handbook of Chemistry and Physics, the student discovers that the density of acetone is 0.790g cm^-3.
Draw structural formulas for the following compounds, and mark any chiral centers (asymmetric carbons) with an asterisk: l-bromobutane, 2- bromobutane
Consider an insulated system containing 150 g of liquid water and 150 g of ice at equilibrium under atmospheric pressure. A total of 22 g of steam at 120±C is admitted to the system.
which is commonly known as table sugar, reacts in dilute acid solutions to form two simpler sugars, glucose and fructose, both of which have the formula C6H12O6 At 23C
Pyridine is a heterocyclic aromatic compound similar in structure to benzene. It is widely used as an organic base because it reacts with acids, but is inert to most reagents.Write an equation with structural formulas to show how pyridine reacts w..
Calculate the pH and the concentrations of all species present H3O+, F-, HF, Cl-, OH- in a solution that contains 0.10 M HF Ka = 3.5*10^-4 and 0.10 M HCl.
Find out the concentration of this solution 1) in m (molality), 2) XHX (mole fraction of HX), 3)% w/w (percent by mass) if solvent in this solution is H 2 O. ?
The pKa values of a compound with two ionizable groups are pKa1 = 4.10 and pKa2 between 7 and 10. A biochemist has 10 mL of a 1.0 M solution of this compoud at a pH of 8.00. She adds 10.0 mL of 1.00 M HCl,
identify the two compounds that are likely to undergo homolytic bond cleavage, and show the mechanism for hemolytic bond cleavage.
