2025 DSE CHEM：補底衝星狂追課程 Vol 09 - 8. Chemical Reactions & Energy 化學反應與能量

喺上堂之前幾日我預先挑戰自己計energy calculation，因為我特別鍾意計呢啲數同埋比較容易，但去到難少少嘅題目就無從入手，不過聽TC教啲難嘅題目同埋DSE題目，自己再做多次發現原來唔係想像中咁難，完全掌握, 之後佢教Formation and Combustion嘅Hess's Law發現自己之前冇留意到題目嘅symbol，後來跟住TC嘅教導完全掌握晒再嘗試做DSE嘅past paper同埋學校quiz，明白之前忽略咗嘅資訊。

Ronald Sir係今次第九期同我哋講解Topic 8 Enthalpy Change 標準焓變嘅最後一個部分Hess's Law 赫斯定律。明白到赫斯定律係條條大路通羅馬, 而且Ronald Sir教我哋點樣畫一個Enthalpy Cycle去計返我哋想要嘅答案出嚟。跟住Ronald Sir仲開埋Topic 9 Rate of Reaction 反應速率, 詳盡咁解釋當中嘅概念同埋題目, 謝謝Ronald Sir嘅教導。

呢期主要將返 microscopic world 內容～
過咗咁耐，自然就會唔太記得初中同一啲比較早學嘅嘢。TC 講得清楚易明，又會配合例子講解～上完可以清返啲 concept 同拆解一啲常見題型，另外仲會俾時間自己試做返啲題目，可以好快 pick up 返。唔明亦可以私底下問返 TC！

上完TC堂之後真係令我對chem依科改觀，原本以為chem只係死背，原來其實唔係，上佢堂真係可以即時清concept睇自己明唔明，因為佢會同我地做好多題目，而且做完後亦會有詳盡解釋，俾我知道自己有啲咩係唔識，thx a lot TC!!!

TC真係好好🥰如果你想清concept，喺考試之前多啲嘅操練，就可以補佢啦因為佢嘅堂真係講得好仔細亦都好令你明白到❤️同埋都有好多練習提供❤️我都係補完佢先知原來有好多concept 我係錯咗嘅，力推力推❤️

TC講解得好清晰同詳細 每一堂嘅教學節奏都ok energy係我最唔熟同最弱嘅topic 但係上堂之後d concept eg hess's law, cycle 清晒 同埋有好多practice 所以學完一個topic可以即刻實戰 睇下自己明唔明個topic

2022 DSE CHEM：補底衝星狂追課程：第 9 期 - 2. Microscopic World I究竟是怎麼樣的存在，始終是個謎題。我想，把2022 DSE CHEM：補底衝星狂追課程：第 9 期 - 2. Microscopic World I的意義想清楚，對各位來說並不是一件壞事。

His lessons are good with interesting ways provided for us to learn conplex concepts in a more memorisable manner, improving our chemistry a lot as concepts are the major part of this subject. The teacher is also very interesting and funny, making jokes and small experiments to keep us intrigued in his lecture and less bored of learning chemistry. Thats something you don't usually see, even in schools.

Tc 把我喺呢一課最唔熟嘅Hess's Law 同 畫Cycle 用唔同練習和例子令我好快上番手。之前做錯過嘅題目都可能即時做番啱，加上MC技巧都十分實用，唔明又可以問問題，讚！

rate of equation 因為係停課，所以真係好唔熟就好似真係冇學過咁，但係T C嘅課堂會由淺至深慢慢講起唔會驚跟唔到。仲有每堂除咗有concept位仲會做操練確保我真係傻。
