Explanation:
In English coordinating conjunctions include the words so, yet, for, and, or, but, so that are used to link elements of the same importance including words, phrases and complete clauses or sentences different to subordinating conjunctions in which the elements link do not have the same importance. This implies, in the case of the sentence "Nalani and I are leaving as soon as we can" the coordinating conjunction is "and" because this links two elements of the same level and importance "Nalani /I" and also this is one of the coordinating conjunctions used in English.
