The solubility of Cl2 in 100 g of water at STP is 310 cm3. Assume that this quantity of Cl2 is dissolved and equilibrated as follows:
(a) If the equilibrium constant for this reaction is 4.7 X 10-4, calculate the equilibrium concentration of HClO formed.
(b) What is the pH of the final solution?
A CFL bulb that puts out as much light as a 60-W incandescent bulb might costs $10, compared to about $1 for the incandescent bulb. But CFL bulbs are expected to last (on average) 15,00 hours, compared to about 1000 hours for an incandescent bulb.
A well pump test was made in a surface layer of sand 10m thick overlying impervious clay. Before the test the water table was at 1.5m depth. After steady state had been reached in the tests
A piston-cylinder device contains 0.2kg of water initially at 800 kPa and 0.06m^3. Now 200 kJ of heat is transferred to the water while its pressure is held constant. Determine the final temperature of the water.

A suspended solid particle of density 2200 kg/m3 is moving at 0.25 m/s of horizontal and 0.15 m/s of vertical velocity respectively in a sedimentation tank. If the depth of the tank is 2.0 m what should be the length of tank to trap the particle i..
A constant-head test was conducted on a sample of soil 15cm long and 60 cm^2 in cross-sectional area. The quantiities of water collected was 50 cm^3 in 20 seconds undera a head difference of 24 cm.
One mole of an ideal monoatomic gas initially at 300 K is expanded from an initial pressure of 10 atm to a final pressure of 1 atm. The molar heat capacity for constant volume for the gas is Cv = 3/2 R .
HZ Wireless must rebuild a cell tower recently destroyed by a tornado. A tower made of normal steel (NS) will cost $30,000 to construct and should last 15 years. Maintenance will cost $1000 per year.
Knowing that the coefficient of kinetic friction between a sled and the run is 0.10 and that the speed of the sled is 25 ft/s at B, determine the tangential component of the acceleration of the sled a) just before it reaches B, b) just after it pa..
