Kiêm Hùng · Accepted Answer

$H_2SO_4+Fe\rightarrow H_2\uparrow+FeSO_4$

$2H_2PO_4+Zn\rightarrow Zn\left(H_2PO_4\right)_2$

$2K+2H_2O\rightarrow2KOH+H_2\uparrow$Câu trả lời: $H_2SO_4+Fe\rightarrow H_2\uparrow+FeSO_4$

$2H_2PO_4+Zn\rightarrow Zn\left(H_2PO_4\right)_2$

$2K+2H_2O\rightarrow2KOH+H_2\uparrow$
