我想問AL term有咩分![]()
![]()
e.g NaOH is hygroscopic
Dse marking就跟CE答absorb moisture in air
其實bio 我都有疑問
e.g thickened cell wall答lignified cell wall
順便係到問下 因為出面無bio post![]()

NaOH要寫deliquescent
如果唔識分hygroscopic同deliquescent就直接寫absorb moisture in air都ok
bio等高手答你啦![]()
我自己無教開bio AL果d又唔記得曬

Lignify好似唔係講cell wall?係講植物嘅structure?
(非AL都想知)

deliquescent係吸水吸到變solution
勁過hygroscopic
好似係
點解NAOH 會吸water & co2?
有冇其他野類似係咁㗎

有冇其他野類似係咁㗎
同水有強affinity既物質都會hygroscopic/deliquescent
例如CaCl2 CaO H2SO4 NaOH KOH
吸CO2通常係strong alkali
例如NaOH同KOH
因為CO2係acidic gas會比佢地中和
CO2 + 2OH- -> CO32- + H2O
同水有強affinity既物質都會hygroscopic/deliquescent
點樣可以知佢係咪?中學雞
究竟graphite係giant covalent structure定simple molecular structure
2012講係giant covalent
2013出張圖又畫到一層層好似simple molecular咁

graphite梗係giant covalent
你要理解”ginat”意指particles之間無止境地互相連結 形成一個3 dimensional network既結構
graphite係layer structure
layer之間的確係vdw force
但佢layer入面無數個C atom form bond with each other 同埋個packing highly regular
已經算係giant structure
O Chem入面Organometal算唔算最難既topic
