The phosphorus (P) balance for the pond is of interest. The concentration of P in the incoming water is 0.2 g/m3 and the P is degraded through various processes in the pond according to a first-order decay model (decay coefficient k s-1). Fish in the pond produce P at a rate of Pprod = 0.00012 g/kg fish/s. a.

A sample of cobalt (II) chloride has 94.0% purity. If the total sample weighs 15604 g, what is the mass of pure cobalt (II) chloride? A. 16600g B. 15600g
Because nuisance thresholds of periphyton growth (150 mg chlorophyll a per m2) were shown to occur at very low concentrations of soluble reactive phosphorus (SRP) (1 -4 ji/g/L), an equation was derived to provide a method for estimating the stream length for which biomass potentially could exceed the threshold.
