C.
Arrhenius
Arrhenius is a Swedish surname most famously associated with Svante Arrhenius, a pioneering chemist and one of the founders of physical chemistry.
-
D.
ionic dissociation theory
Ionic dissociation theory is a scientific concept that explains how certain substances split into charged ions when dissolved in water, accounting for their electrical conductivity and behavior in solution.

Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
