Final answer:
The question from the student concerns chemistry topics, more specifically, it involves the ionic properties (size and charge) of sodium and potassium ions, and the principle of chemical equilibrium in acid-base reactions.
Step-by-step explanation:
The student's questions relate to the comparison of ionic radii, charges, and chemical equilibrium, which are all central topics in chemistry. Specifically, these questions address the relative sizes of sodium (Na+) and potassium (K+) ions, the comparison of charges between different ions and atoms, and the concept of equilibrium constants (K) as they pertain to acids and bases.
'[Na+] is greater_______ than _______ .' This statement could be completed with '[Na+] is greater in extracellular fluid than intracellular fluid.' - referring to the biological distribution of ions. In terms of charge, '[K+] is greater_______ than _______.' would likely refer to the comparison of ionic charges or concentrations in different contexts. For example, '[K+] is greater in intracellular fluid than extracellular fluid.'
In discussing equilibrium, such as 'K = 888... greater concentration of products than reactants', we are engaging with the concept that a high K value indicates a reaction that favors product formation over reactant formation, which is a principle in acid-base chemistry.
