aim *除咗溫錯題同MS仲有乜可以做?
2022-04-28 17:59:38
基本上就係咁多啦我覺得
2022-04-28 18:07:00
仲可以睇下啲定義啦 嗰一兩分有時真係幾重要
硬性知識 D 實驗set up圖
最後幾日真係都係溫呢啲
最多最多再計時做一次一年嘅卷
希望幫到你

當年將書局所有dse Chem 買曬
考試嗰時45分鐘做曬paper1
而家都覺得癲
2022-04-28 18:38:21
同問，同埋想知做街外mock有冇用
2022-04-28 18:51:42
最後咩grade

其實唔太有用
我覺得CHEM DSE/CE已經好夠做
中四中五可以操下CE by topic
中六就操DSE 已經好足夠

師兄呢個少癲
45分鐘有啲人MC都未必做完

有冇咩冷門definition推薦要背，因為上年第一年出markovnikov rule，驚今年又咁樣考
2022-04-28 20:23:43
ok 感謝您
2022-04-28 20:24:03
好的感謝您

搭單問 allotropes def 使唔使背
同埋hydrogen bond def 寫
weak electrostatic force of attractions between a hydrogen atom of a highly polarized bond of an molecule and a lone pair electrons of a highly electronegative atom of another atom 得唔得

而家考dse 變咗賽跑鬥快

其實我建議有時間真係loop一次textbook睇下有咩定義 其實好多背唔曬 但你唔一定要exact wording寫出黎 講到大概完整意思就得
不過當然呢個真係你有時間先做 始終定義考你多數係一分 你依家花時間去loop textbook其實性價比唔高 呢啲應該一早睇 佢隨時乜嘢定義都可以問你
不過當然有啲常考嘅例如Hess’s law/standard enthalpy change of ____ 個啲就當然係記定入場

Hydrogen bond: electrostatic attraction between the partial positively charged H that bonded with highly electronegative atom (N/O/F) with lone pair electrons on the highly electronegative atom (N/O/F) of another molecule.
2022-04-28 23:52:52
呢個如果同學仔覺得難記
我建議畫個圖 例如兩個H-F之間個hydrogen bond
之後自己用英文描述所有你見到嘅嘢

我Carbon compound 嗰課好廢(synthetic route 同 important organic substance)，可以點操練/温？
2022-04-30 18:54:17
背marking la
synthetic route你要溫咗chemical reaction of organic compound先 背曬自然記得
呢兩年其實已經好少考
organic substance方面, detergent嚟嚟去去都係嗰啲, aspirin背功效副作用structure都差不多
