Question

Fe(OH)3+HCl=FeCl3+H2O Fe(OH)3+H2SO4=Fe2(SO4)3+H2O Mg(OH)2+HCl=MgCl2+H2O Mg(OH)2+H2SO4=Mg(SO4)+H2O Co(OH)2+HCl=CoCl2+H2O Co(OH)2+H2SO4=Co(SO4)+H2O

Answer 1

2Fe(OH)3+6HCl=2FeCl3+6H2O2Fe(OH)3+3H2SO4=Fe2(SO4)3+6H2O
Mg(OH)2+2HCl=MgCl2+2H2O
Mg(OH)2+H2SO4=Mg(SO4)+2H2O
Co(OH)2+2HCl=CoCl2+2H2O
Co(OH)2+H2SO4=Co(SO4)+2H2O

Answer 2

The chemical equations you've provided are not balanced correctly. Here are the correctly balanced versions:

1. Fe(OH)3 + 3HCl → FeCl3 + 3H2O
2. Fe(OH)3 + 3H2SO4 → Fe2(SO4)3 + 6H2O
3. Mg(OH)2 + 2HCl → MgCl2 + 2H2O
4. Mg(OH)2 + H2SO4 → MgSO4 + 2H2O
5. Co(OH)2 + 2HCl → CoCl2 + 2H2O
6. Co(OH)2 + H2SO4 → CoSO4 + 2H2O

These equations represent the balanced chemical reactions for the reactions you provided.
