Aclosed-loop ecosystem is being designed for long-duration space missions. within that system, a biofilter will utilize bacteria to convert nitrogen from fish waste (nh3) into a form usable by plants ( the biofilter consists of a cylinder filled with spherical particles (like a jar full of marbles) upon which the bacteria attach, and water then flows through the cylinder past the bacteria. the water flow rate through the system is 25 g h20 / s, and the inlet concentration of nh3in the water is 9x10-6g nh3/ g h20. if the bacteria in the filter are removing nh3at a rate of 41x10-6(g nh3)/s, what is the concentration of nh3in the outlet water, in g nh3/ g h20?

For ai it's atomic number is 13 and it's mass number is 27 how many neutrons does it have

Many reactions take place in aqueous solution. when potential reactants are mixed, a reaction will occur if there is some driving force that favors the formation of products. it is often convenient to categorize reactions in terms of these driving forces: precipitate formation, in which an insoluble solid is formed, weak electrolyte formation, as in a neutralization reaction involving water, or transfer of electrons, as in a redox reaction. these reactions can be represented by full molecular equations, which contain all species in the reaction mixture, or by net ionic equations, which show only the species that actually undergo a change. the latter does not contain the spectator ions, which do not undergo a net change or do not take part in the reaction. part a when the following two solutions are mixed: k2co3(aq)+fe(no3)3(aq) the mixture contains the ions listed below. sort these species into spectator ions and ions that react. drag the appropriate items to their respective bins. view available hint(s) spectator ions ions that react part b what is the correct net ionic equation, including all coefficients, charges, and phases, for the following set of reactants? assume that the contribution of protons from h2so4 is near 100 %.ba(oh)2(aq)+h2so4(aq)→ express your answer as a chemical equation. view available hint(s) nothing provide feedback
