How many pounds of oxygen is transferred per day to a water volume (12334.8 m3) assuming one 9" air station and:
standard oxygen transfer efficiency (sote) = .10 %
standard cubic feet per minute (scfm) air flow = 1 scfm
approx density of air = 0.075 (lb/ft3)
the weight percent of oxygen in air = 0.232 %
minutes per day = 1440 min

An atom of lithium (li) and an atom of chlorine (cl) engage in a chemical reaction. which correctly describes the structure of the resulting chemical compound? hint: consider the class of each element. the chemical compound will have a network structure. the chemical compound will have triple bonds. the chemical compound will have a ball-and-stick structure. the chemical compound will have double bonds.

Which of these conditions most likely produces an unstable isotope?
