Entre los seres vivos de un ecosistema, la energía fluye en un solo sentido, desde los organismos autótrofos, o productores, es transferida hacia los consumidores mediante las relaciones alimentarias. En cada transferencia, se producen grandes pérdidas de energía en forma de calor, el cual es emitido al ambiente. Cuanto de energía se pierde en cada eslabón de la cadena trófica

What is the mass of 8 moles of sodium atoms

Fill in the coefficients that will balance the following reaction: a0cr2(so4)3 + a1agno3

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
