$2Zn+O_2-^{t^o}\rightarrow2ZnO$

$ZnO+2HCl\rightarrow ZnCl_2+H_2\uparrow$

$ZnCl_2+2KOH_{\left(vừa-đủ\right)}\rightarrow Zn\left(OH\right)_2+2KCl$

$Zn\left(OH\right)_2+H_2SO_4\rightarrow ZnSO_4+2H_2O$Câu trả lời: $2Zn+O_2-^{t^o}\rightarrow2ZnO$

$ZnO+2HCl\rightarrow ZnCl_2+H_2\uparrow$

$ZnCl_2+2KOH_{\left(vừa-đủ\right)}\rightarrow Zn\left(OH\right)_2+2KCl$

$Zn\left(OH\right)_2+H_2SO_4\rightarrow ZnSO_4+2H_2O$
