Boyle's law for the expansion of gas PV=C.At a certain instant,the pressure is 2000 lb./ft², the volume is 8 ft³, and the volume increasing at the rate of 6 ft³/mm. Find the rate of change of the pressure at this time

There is a total of 100 g of Propane (C₃H₈) left in a tank. How much Carbon and Hydrogen in g and % is in 100 g of Propane?

A city when its operation is normal uses a supply of drinking water

containing 15 mg /L of chloride (Cl-), but during periods of high water demand,

mixes with groundwater containing 65 mg/L Cl-. The two waters mix

completely in a 1400 m3 tank and then sent to the distribution system. the

demand for many days has been ~500 m3/d, and all the water has come from

the main supply. So, the demand increases to 700 m3 /d, and the additional

200 m3/d is extracted from the groundwater supply. How long can

continue with this operating strategy before the water entering the

distribution system contains ≥ 20 mg/L Cl-? (Note: chloride is not reactive).
