The spelling of the word "calcii henzoas" has origins in Latin, where "calcii" refers to calcium and "henzoas" refers to hydrazines. In IPA phonetic transcription, "calcii" is pronounced as /ˈkælsiː/ with emphasis on the first syllable and the "ii" representing the Latin plural marker. "Henzoas" is pronounced as /hɛnˈzoʊəs/, with emphasis on the second syllable and the "oa" representing a diphthong. The combination of these two words describes a category of chemicals that contain both calcium and hydrazines.
