主攻化學的人或大ㄧ普化的人請進

這次普化期中考全班考得很慘

老師要我們回去找出答案然後訂正but我真的都不懂

更別說訂正

所以想請大大幫我解以下題目注意: 除了第一大題外

其他答案請用中文

我個人提供 ㄧVocabulary1.熱化學 2.石油(不是oil) 3.輻射 4.週期性 5.鹼金屬二 Please explain the following problems in detail1.What is the 1st of thermodynamics?2.What are four kinds of quantum?3.What is X-ray diffraction?4.What is electron affinity and ionization energy?三 Calculation1. From energy level n=4 to n=1

find energy released?(by Bohr model )四 Electron configuration 95X
ㄧVocabulary1.熱化學 :thermochemistry2.石油(不是oil) :petroleum3.輻射 :radiation4.週期性 :periodicity5.鹼金屬:alkali二 Please explain the following problems in detail1.What is the 1st of thermodynamics?什麼是熱力學第一定律dQ=dU dw 或dQ=dU-dw 看你功怎麼定義正負

兩者皆可熱力學第一定律就是能量不滅定律2.What are four kinds of quantum?請說明4種量子數一.the principal quantum quantum number 主量子數 n二.subsidiary quantum number 量子數 l三.magnetic quantum number 磁量子數 m四.magnetic spin quantum number 自旋量子數 s3.What is X-ray diffraction?什麼是x光繞射Bragg
