    Đáp án:

    1.$CO_{2}$ + $Ca(OH)_{2}$ $–>$ $CaCO_{3}$ $+$  $H_{2}O$ 
    2.$SO_{3}$ $+$  $2NaOH$ $–>$ $Na_{2} SO_{4}$ +  $H_{2}O$  
    3.$K_{2}O$+ $SO_{3}$ –>  $K_{2}SO_{4}$ 
    4.$CaO$ + $CO_{2}$ –>  $CaCO_{3}$
    5.$CuO+2HCl$ $–>$ $CuCl_{2}$+ $H_{2}O$ 
    6.$ZnO+2HCl$ –> $ZnCl_{2}$+ $H_{2}O$ 
    7.$Al_{2}O_{3}$+  $3H_{2}SO_{4}$ –> $Al_{2}(SO_{4})_{3}$ + $3H_{2}O$ 
    8.$CaO+$$H_{2}O$  –> $Ca$$(OH)_{2}$

    $ CO2+Ca(OH)2  → H2O + CaCO3↓$ 

    $ SO3+2NaOH → H2O + Na2SO4 $

    $K2O + SO3 → K2SO4$

    $CaO + CO2 → CaCO3↓$

    $CuO + 2HCl ⟶ H2O + CuCl2$ 

    $ZnO + 2HCl ⟶ H2O + ZnCl2$ 

    $Al2O3 + 3H2SO4 → Al2(SO4)3 + 3H2O $

    $CaO + H2O → Ca(OH)2$
