Apolluted lake with a constant volume 10*10^6 m3 is fed by a pollution-free stream with flow rate qs=5 m3/s that has a contaminant concentration cs=10 mg/l. a factory dumps 5 m3/s of a non-conservative waste with concentration cw= 100 mg/l into the lake. the pollutant has a reaction rate coefficient k of 0.2/day and the reaction is first-order decay. assuming the pollutant is well mixed in the lake, find the steady-state concentration of pollutant in the lake.

i believe it is a.) released into

explanation:

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
