Achemical plant produces an ammonia-rich waste gas that cannot

be released as-is into the environment. one method to reduce the

ammonia concentration in the waste gas is to bubble the waste gas

through a liquid solvent. components of the gas that are highly

soluble, like ammonia, will dissolve into the liquid phase. water

is an appropriate liquid solvent for this process. the chemical

plant produces 115.0 m3/hr of waste gas (? = 0.0407 mol/l)

initially having a mole fraction of 0.120 nh3, and wishes to remove

90.0% of the initial amount of nh3. the maximum concentration of

ammonia in water at this temperature is 0.4000 mol nh3/ mol water.

neglect the absorption of other waste gas components into the

water, and the evaporation of water into the waste gas stream.

i would expect light rain in pittsburgh throughout the following 24 to 48 hours. the lower/falling weights in urban areas toward the west demonstrate that a low weight framework is moving from west to east toward pittsburgh. low weight frameworks are ordinarily connected with precipitation. the way that you don't see a major drop in temperature in the more western urban areas demonstrates the low weight framework is moving with a warm front, so just light rain would be normal. substantial downpours or progressively vicious climate is just typically connected with chilly fronts, where the warm air is pushed up and over a cool front quickly. this quickly rising air (convection) is what gives you heavier torrential downpours, and other conceivably serious weather conditions.
