化学式 AL+h2so4=== MG+H2SO4=== K+H2SO4=== NA+H2SO4=== ZN+HCI=== FE+HCL=== AL+HCL==== MG+HCI====
答
2Al+3H2SO4=Al2(SO4)3+3H2
Mg+H2SO4= MgSO4+H2
2K+H2SO4= K2SO4+H2
2Na+H2SO4= Na2SO4+H2
Zn+2HCI= ZnCl2+ H2
Fe+2HCL= FeCl2+ H2
2Al+6HCL== 2AlCl3+ 3H2
Mg+2HCI== MgCl2+ H2
答
2Al + 3H2SO4 == Al2(SO4)3 + 3H2↑Mg + H2SO4 == MgSO4 + H2↑2K + H2SO4 == K2SO4 + H2↑2Na + H2SO4 == Na2SO4 + H2↑Zn + 2HCl == ZnCl2 + H2↑Fe + 2HCl == FeCl2 + H2↑2Al + 6HCl == 2AlCl3 + 3H2↑Mg + 2HCl...
