Question

Hoàn thành các phương trình sau

1. Fe(OH)₃ ^_____> ? + H2O​

2. Al(OH)3 ^_____> ? + H2O

4. HgO ^______> ? + ?

5. C2H2 + O2 ^_____> ? + H2O

6. CO2 + H2O ^{______> ?}

Answer 1

2Fe(OH)₃ -> Fe₂O₃ + 3H₂O

2Al(OH)₃ -> Al₂O₃ + 3H₂O

HgO -> Hg + \(\frac{1}{2}\)O₂

C₂H₂ + \(\frac{5}{2}\)O₂ -> 2CO₂ + H₂O

CO₂ + H₂O -> H₂CO₃

Answer 2

Hoàn thành các phương trình sau

1. 2Fe(OH)3 --t^o--> Fe2O3 + 3H2O​

2. 2Al(OH)3 --t^o --> Al2O3 + 3H2O

4. 2HgO __450-500^oC__> 2Hg +O2

5. C2H2 + \(\frac{5}{2}\)O2 __t^o___> 2CO2+ H2O

6. CO2 + H2O <==> H2CO3

Answer 3

2Fe(OH)3--->Fe2O3+H2O

2Al(OH)3--->Al2O3+3H2O

2HgO--->2Hg+O2

2C2H2+5O2---->4CO2+2H2O

CO2+H2O--->H2CO3
