標題: F4 CHEM+校報問題


校報最近有個關於收藏家嘅題目
我搵左好奈都搵唔到
所以想問下大家知唔知有一D有特殊收藏(姐係冇咁大路)嘅收藏家
希望各位有嘅可以提供一下
求救!
THX

另外
CHEM一問
題目係咁:
write an ionic equation for each of the following equation

C) IRON+COPPER(II) SULPHATE SOLUTION
D)COPPER+ SILVER NITRATE SOLUTION

C) Fe(s) + CuSO4(aq) > FeSO4(aq) + Cu(s)
Fe and Cu are insoluble in Water, Sulphates are generally soluble in water, they completely dissociate and form ions
Fe + Cu2+ + SO4 2- > Fe2+ + SO4 2- + Cu
Fe(s) + Cu2+(aq) > Cu(s) + Fe2+(aq)
* Sulphate ions are spectator ions.

D) Cu(s) + 2AgNO3(aq) > 2Ag(s) + Cu(NO3)2(aq)
Ag and Cu are insoluble in Water, Nitrates are soluble in water, they completely dissociate and form ions
Cu + 2Ag+ + 2NO3 - > Cu2+ + 2NO3 - + 2Ag
Cu(s) + 2Ag+(aq) > Cu2+(aq) + 2Ag(s)
* Nitrates ions are spectator ions.
chem的我識答(還望求證)，但是收藏就幫不了zzz

感謝指教
上面條式我CHECK過冇錯
其實我發現老師都好似未教IONIC equation
所以想再請教下
下面嘅2條式咁我應該寫邊條?

我想該是下面那兩道吧。

其實...應該係following reaction而唔係following equation吧...
