Fe+HCl = Ca+H²O= PbO²+H²= Al²O³+H²=

Question

Fe+HCl =

Ca+H²O=

PbO²+H²=

Al²O³+H²=

Answer 1

2Fe + 6HCl = 3H₂ + 2FeCl₃

 

Ca + 2H₂O = Ca(OH)₂ + H₂

 

PbO₂ + H₂ = PbO + H₂O

 

Al₂O₃ + 3H₂ = 2Al + 3H₂O

Answer 2

1)  2Fe + 6HCl = 3H₂ + 2FeCl₃

 2)Ca + 2H₂O = Ca(OH)₂ + H₂

 3)PbO₂ + H₂ = PbO + H₂O

 4)Al₂O₃ + 3H₂ = 2Al + 3H₂O
