Answer 1

1: \(Na_2O+H_2O->2NaOH\)

2: \(2Na+2H_2O->2NaOH+H_2\uparrow\)

3: \(2Al\left(OH\right)_3\underrightarrow{t^o}Al_2O_3+3H_2O\)

4: \(Al_2O_3+6HCl->2AlCl_3+3H_2O\)

5: \(FeO+2HCl->FeCl_2+H_2O\)

6: \(4P+5O_2\underrightarrow{t^o}2P_2O_5\)

7: \(N_2O_5+H_2O->2HNO_3\)

8: \(Zn+2HCl->ZnCl_2+H_2\)

9: \(2Al+3CuCl_2->2AlCl_3+3Cu\downarrow\)

10: \(2Al+3H_2SO_4->Al_2\left(SO_4\right)_3+3H_2\uparrow\)

1. \(Na_2O+H_2O\rightarrow2NaOH\)

2. \(2Na+2H_2O\rightarrow2NaOH+H_2\)

3. \(2Al\left(OH\right)_3\underrightarrow{t^o}Al_2O_3+3H_2O\)

4. \(Al_2O_3+6HCl\rightarrow2AlCl_3+3H_2O\)

5. \(FeO+2HCl\rightarrow FeCl_2+H_2O\)

6. \(4P+5O_2\underrightarrow{t^o}2P_2O_5\)

7. \(N_2O_5+H_2O\rightarrow2HNO_3\)

8. \(Zn+2HCl\rightarrow ZnCl_2+H_2\)

9. \(2Al+3CuCl_2\rightarrow2AlCl_3+3Cu\)

10. \(2Al+3H_2SO_4\rightarrow Al_2\left(SO_4\right)_3+3H_2\uparrow\)
