Zn+H2SO4=ZnSO4 2Zn+O2=2ZnO Ba(OH)2+ZnSO4=BaSO4+Zn(OH)2 ZnO+H2O=Zn(OH)2 Zn(OH)2=ZnO+H2O
ZnSO4(aq)→ Zn2+(aq) + SO42-(aq) Cu2+(aq) + SO42-(aq) + Zn(OH)2(s) = Cu(OH)2(s) + Zn2+(aq) + SO42-(aq) Spectator Ions Spectator ions are ions that do not take part in the reaction. They are removed from the complete ionic equation to get the net ionic equation...

求救,ZnSO4+N..二模题,老师说有问题,我配不平。加个氨水好像就可以……但是题里就说碳酸氢铵与硫酸锌复分解反应生成碱式碳酸锌和另一种物质。答案是硫酸铵……
可写2 NaOH+ ZnSO4= Zn(OH)2↓ +Na2SO4或2 NaOH+ FeSO4= Fe(OH)2↓ +Na2SO4 (2)操作a将反应后的物质分成了固体和液体,所以该操作为过滤。过滤需要漏斗。玻璃棒的作用主要是引流,以防液体溅出造成不必要的事故。 (3)因第一步加氢氧化钠至PH=9.6,Zn(OH)2和Fe(OH)2二者全部沉淀,生成...
