Question

Al + HCl \(\rightarrow\) Al2O3 + H2

Al2O3 +HCl ​\(\rightarrow\)​ AlCl3 + H2O

AlCl3 + NaOH ​\(\rightarrow\)​Al(OH)3 + NaCl

Answer 1

2Al + 6HCl ===> 2AlCl₃ + 3H₂ (PT này bạn viết sai sản phẩm nhé !)

Al₂O₃ + 6HCl ==> 2AlCl₃ + 3H₂O

AlCl₃ + 3NaOH ==> Al(OH)₃ + 3NaCl

Answer 2

2Al + 6HCl 2AlCl3 + 3H2

Al2O3 +6HCl ​​ 2AlCl3 + 3H2O

AlCl3 + 3NaOH ​Al(OH)3 + 3NaCl

Answer 3

2Al + 6HCl $\to$ 2Al2Cl3 + 3H2 ( sai phương trình nên t sửa luôn )

Al2O3 +6HCl ​$\to$​ 2AlCl3 + 3H2O

AlCl3 + 3NaOH ​$\to$​Al(OH)3 + 3NaCl

Answer 4

\(Al_2O_3+6HCl->2AlCl_3+3H_2O\)
\(AlCl_3+3NaOH->Al\left(OH\right)_3+3NaCl\)
