Fertilizers have nutrients that plants grow. sometimes, when it rains, fertilizers are washed away from farmland into ponds and lakes. this promotes the growth of algae, a type of plant, present in the water. it is observed that algae grow very fast and cover the surface of the pond completely. they use up all the dissolved oxygen in the pond. how does this affect the other organisms in the pond?
a) they start eating algae.
b) they do not get enough oxygen, and die.
c) they get entangled in the algae, and die.
d) they leave the pond and go to live elsewhere.

Find the mass in grams of 1.37x1020 particles of h3po4

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
