同我阿SIR一九樣,我地班唔係訓果D,就吹水,佢繼續自己講俾自己聽,佢條友照讀PP上面D字,真係俾佢吹九漲,我唔識睇咩,你真係教番少少有幫助架啦,出卷又求其,份MOCK集合晒各年PP最淺既題目,等我唔溫都有5X分,而家出 ...
我阿sir份mock仲醒, 用0304組成,連number都唔改, 連section一樣...
不過都係得一個合格..:icon110:

個個合格既仲要係因為份essay20分先合格...
但係in fact佢無嘜points...阿sir話送分...
得1句既都有分...5分...:icon112::icon114:

大家同病相憐啦
唉..
要垃圾, 要求其都有限度丫..
簡直係置學生生死於不顧...
paper II都算淺... esp. organic... no.5有機full mark (個enthalpy change... 係咪一個-48.XX, 一個-46.XX?)
但paper I真係.................
篇essay死得好慘
5分都唔知有冇 (因為我冇寫最重要既野-----fuel cell)
又寫左好多air pollution既野 -______-
我諗得50%左右... 好差
btw, 到底有冇人知Paper II 4(b)點做?

enthalpy change 起碼過千...
無可能咁少.
----------
4b
i)
Path I: Al + dil H2SO4 ---> product + NaOH
Path II: Al + NaOH + H2O --> product --> NaOH.....(唔知arm唔arm, 無讀inorg)
ii)
計數only
iii)
Path I, 用少d料

for enthalpy change:
what I mean is part (ii)... the enthalpy change of combustion of gasoline with/without enthanol
for no. 4(b)
path I:
2 Al + 3 H2SO4 ---> Al2(SO4)3 + 3 H2
Al2(SO4)3 + 6 NaOH ---> 2 Al(OH)3 + 3 H2O
path II:
Al + 3 H+ ---> Al3+
Al3+ + 3NaOH ---> 3 Na+ + Al(OH)3
Al(OH)3 + NaOH ---> Na (due the excess NaOH)
Na + H+ ---> Al(OH)3 + H2O + Na+
path II is better as it ensures that all Al(s) is converted to Al(OH)3
不過應該唔岩... 太天馬行空喇
同埋... 有咩辦法可以盡快拎到paper I既題目?
想predict自己拎幾多... 安心D

我都好似係,你驚唔驚:icon101:

佢per g喎,唔係per mol喎:confused:

no la
paper II都還好 (應該過七成)
但paper I死得好慘
C應該冇問題
但B就唔得喇 (阿sir一定大跌眼鏡)
睇黎我都諗定year 2點transfer (如果我有幸入U)
