各位中六同學，星期四到我科CHEM啦! 老實說，實力已有LV5或以上的同學都應該明白，平時自己花左幾多時間和苦功去讀，所以你地應該知道讀多一兩日其實唔會有太大改變。不過好多同學問我呢兩日應該點讀，我都可以比少少意見大家。 同學請將我平時在堂上教大家的練習(包括Regular和All-round Intensive)都做一次(記住只係做上堂教個d)。原因很簡單，我平時一星期只見大家一次，時間不多，所以我設計課堂練習都係以做最少題目cover到最多concept和技巧為原則。記住，因為時間不足，做短答題時可以心中做一次，即對答案。如果係計數題，同學就必須自己拎張白紙計一次，再對答案。 另外有幾樣野係必讀的(仲要超熟): Solubility table, Kelvin’s table (part 1 + part 2), Section 3, 4, 7的所有反應和平衡技巧(呢d係基本功，唔識就必定要做返好先，再去讀其他)。 背定義: Isotope(同位素), relative atomic mass(相對原子質量), dative covalent bond(配位共價鍵), rusting(生銹), base(鹽基), acid(酸), alkali(鹼), basicity(鹽基度), fossil fuel(化石燃料), VSEPR theory(價層電子對相斥學說), redox reaction(氧化還原反應), disproportionation(歧化作用), standard states(標準態), standard enthalpy change (formation, combustion, neutralization)(標準生成焓變、燃燒焓變、中和焓變), Hess’s law(赫斯定律), activation energy(活化能)… 同學請記住，要對我有信心，我平時教大家的已經超級多和深入，同學唔洗再額外出去找其他野讀，只要熟讀我平時教的，已經好夠。加油!!!
