$\text{b) FeO + $H_{2}$$\xrightarrow{t^o}$Fe + $H_{2}O$}$

$\text{c) Zn + $H_{2}SO_{4}$→$ZnSO_{4}$ + $H_{2}$}$

$\text{d) $SO_{3}$ + $H_{2}O$→$H_{2}SO_{4}$}$

$\text{e) $P_{2}O_{5}$ + $3H_{2}O$→$2H_{3}PO_{4}$}$

$\text{f) 2Na + $2H_{2}O$→2NaOH + $H_{2}$}$

$\text{g) CaO + $H_{2}O$→$Ca(OH)_{2}$}$

$\text{h) Ba + $2H_{2}O$→$Ba(OH)_{2}$ + $H_{2}$}$

$\text{i) $Fe_{3}O_{4}$ + $4H_{2}$$\xrightarrow{t^o}$3Fe + $4H_{2}O$}$

$\text{j) $N_{2}O_{5}$ + $H_{2}O$→$2HNO_{3}$}$

$\text{k) 2Cl + $H_{2}SO_{4}$→ 2HCl + $SO_{4}$}$

$\text{l) Ca + $2H_{2}O$→$Ca(OH)_{2}$ + $H_{2}$}$

2Al + 6HCl -> 2AlCl3 + 3H2

FeO + H2 -> Fe + H2O

Zn + H2SO4 -> ZnSO4 + H2

SO3 + H2O -> H2SO4

P2O5 + 3H2O -> 2H3PO4

 2H2O + 2Na -> 2NaOH + H2

CaO + H2O -> Ca(OH)2

2H2O + Ba -> Ba(OH)2 + H2

4H2 + Fe3O4 -> 3Fe + 4H2O

H2O + N2O5 -> 2HNO3

H2SO4 + Cl -> HCl + SO4

Ca + 2H2O -> Ca(OH)2 + H2
