Standard enthalpy of formation equation
标准生成焓计算式
Explanation (EN)
ΔrH° = Σν·ΔfH°(products) − Σν·ΔfH°(reactants), using stoichiometric coefficients ν.
Explanation (ZH)
ΔrH° = Σν·ΔfH°(生成物) − Σν·ΔfH°(反应物),其中 ν 为化学计量系数。
About the IPA
The International Phonetic Alphabet is a standardized system of symbols used to represent the sounds of spoken language.
It helps linguists, language learners, and educators accurately describe pronunciation across languages.
Example: the word "hello" in British English is transcribed as /həˈləʊ/ in IPA.
