條calibation curve應該係向上?logr0=logk+alogS2O32-
a=slope=order of reaction=1咁present得唔得
同埋前面in chem個membrane cell solution 寫diluteNaOH OK?

真考生

Q21 D.
Formation of CO: C(graphite) + 1/2O2(g) --> CO(g)
Combustion of graphite: C(graphite) + 1/2O2(g) --> CO(g)
They are the same
Formation of CO: C(graphite) + 1/2O2(g) --> CO(g)
Combustion of graphite: C(graphite) + 1/2O2(g) --> CO(g)
They are the same
有冇卷？
Not C+ O2->co2 meh
應該係a,
Electrolyte :substance that produce free ions when dissolving in water
Electrolyte :substance that produce free ions when dissolving in water
graphite個C變CO未burnt.completely符合定義?
Combustion of graphite 唔係應該出CO2咩？
Oh
hg metal 唔計
上年見到你 你 retake?
上年見到你 你 retake?
Formation of carbon monoxide, not carbon dioxide
漏咗molten state
Combustion of Graphite出到兩種product, 冇可能直接用嚟搵CO嘅∆Hf
可能LQ啱曬呢
同埋Chem嘅cut-off都唔係高得好誇張
同埋Chem嘅cut-off都唔係高得好誇張
係喎我寫錯了
咁應該係A
咁應該係A
Wrong… the definition is complete combustion so ans should be A
