Question

hãy cân bằng các phương trình hóa học sau :

1. Al(OH)₃ --------> Al₂O₃+ H₂O

2. Al₂O₃ + HCl ---------> AlCl₃ + H₂O

3. Al + HCl --------> AlCl₃ + H₂⬆️

4. FeO + HCl --------> FeCl₂ + H₂O

Answer 1

1. 2Al(OH)₃ ------> Al₂O₃+ 3H₂O

2. Al₂O₃ + 6HCl ---------> 2AlCl₃ + 3H₂O

3. 2Al + 6HCl --------> 2AlCl₃ + 3H₂

4. FeO + 2HCl --------> FeCl₂ +H₂O

Answer 2

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

2) Al₂O₃ + 6HCl → 2AlCl₃ + 3H₂O

3) 2Al + 6HCl → 2AlCl₃ + 3H₂

4) FeO + 2HCl → FeCl₂ + H₂O

Answer 3

1)2Al(OH)₃-->Al₂O₃+3H₂O

2)Al₂O₃+6HCl-->2AlCl₃+3H₂

3)2Al+6HCl-->2AlCl₃+3H₂

4)FeO+2HCl-->FeCl₂+H₂O
