5. an aquaculture tank is used to grow fish and generates a significant amount of debris and particulate matter during operation. the wastewater from this system can be used as plant fertilizer, but the particles must be removed via settling prior to use in the hydroponic growing system (a system of long, rectangular troughs that are used for cultivating plants). given the parameters here, answer the following questions:

- the flow rate into the hydroponic system is 15 l/min.

- the temperature of the water is 15 °c.

- the particles are uniform and spherical, 15 µm in diameter.

- the average particle density is 1.8 g/cm3.

a. if plants are grown on hydroponic troughs that are 1.25 m wide, and no sedimentation tank is built, how far along the troughs (horizontal distance) will the particles travel before settling?

What is the maximum number of electrons that an atomic orbital can contain?

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

Describe what happens to the molecules as water goes from ice to liquid to vapor. be sure to explain what happens to the temperature during the phase changes.
