Bạn ghi ko rõ ràng( dấu cộng ko có, mũ thì không rõ là ở đâu, ít nhất bạn ghi mũ 3 như ^3)
Nói chung là bạn gửi lại cho mình để mình làm cho, nhớ ghi rõ ra nhé
\(\left(1\right)4Al+3O_2\rightarrow2Al_2O_3\)
\(\left(2\right)Al_2O_3+6HCl\rightarrow2AlCl_3+3H_2O\)

bạn tự cân bằng nhé chứ ko lâu lắm
a) \(S+O_2-to>SO_2\)
\(SO_2+O_2-\frac{to}{xt}>SO_3\)
\(SO_3+H_2O->H_2SO_4\)
\(NaOH+H_2SO_4->Na_2SO_4+H_2O\)
\(BaCl_2+Na_2SO_4->BaSO_4+NaCl\)
4Al + 3O2 → 2Al2O3
Al2O3 + 6HNO3 → 2Al(NO3)3 + 3H2O
Al(NO3)3 + 3NaOH → Al(OH)3 + 3NaNO3
2Al(OH)3 | → | Al2O3 | + | 3H2O |
Al2O3 + 6HCl → 2AlCl3 + 3H2O
2AlCl3 | → | 2Al | + | 3Cl2 |

Chúc bạn học tốt! Thân ái!
a)
+ 4Al + 3O2 =(nhiệt)=> 2Al2O3
+ Al2O3 + 6HNO3 ===> 2Al(NO3)3 + 3H2O
+ Al(NO3)3 + 3NaOH ===> 3NaNO3 + Al(OH)3
+ 2Al(OH)3 =(nhiệt)=> Al2O3 + 3H2O
