Question

cân bằng PTHH sau

1) Al (OH)₃ -> Al₂O₃ + HO₂

2) Al₂ O₃ + HCl - > AlCl₃+ HO₂

Answer 1

1) 4Al(OH)3 \(\rightarrow\) 2Al2O3 + 6H2O

2) Al2O3 + 6HCl \(\rightarrow\) 2AlCl3+ 3H2O

Answer 2

1) 2Al(OH)3 Al2O3 +3H2O

2) Al2O3 + 6HCl 2AlCl3+ 3H2O

Answer 3

1. \(2Al\left(OH\right)_3\rightarrow Al_2O_3+3H_2O\)
2. \(Al_2O_3+6HCl\rightarrow2AlCl_3\downarrow+3H_2O\)

Answer 4

1) 2Al(OH)₃ -->Al_​2O₃+3H₂O

2)Al₂O₃+6HCl -> 2AlCl₃ +3H₂O

Answer 5

1) 2Al(OH)₃ \(\underrightarrow{to}\) Al₂O₃ + 3H₂O

2) Al₂O₃ + 6HCl → 2AlCl₃ + 3H₂O
