Write the equilibrium-constant expression for the reactionA(s)+3B(l)↽−−⇀2C(aq)+D(aq)A (s)+3B(l)↽−−⇀2C(aq)+D(aq)in terms of [A], [B], [C], and [D] as needed. Note that KcKc, which is sometimes symbolized as KeqKeq, denotes that the equilibrium constant is expressed using molar concentrations. For this question, KcKc means the same thing as KeqKeq. Kc=.

Which element in the third period would you expect to have the larger atomic radius, sodium (na) or sulfur (s)? a. sodium, because it has a higher effective nuclear charge attracting electrons in fewer energy levels. b. sodium, because it has fewer protons attracting electrons in the same energy levels. c. sulfur, because it has more protons attracting electrons in more energy levels. d. sulfur, because it has a higher effective nuclear charge attracting electrons in the same energy levels.
