Answer

when bases react with non-metal oxides, then salt and Water are Formed.
Example: Calcium hydroxide reactswith corbon dioxxide to from culcium carbonate and water.
$\underset{\substack{\text { Calcium hydroxide } \\ \text { (Base) }}}{ Ca ( OH )_{2(a q)}}+\underset{\substack{\text { Carbon hydroxide } \\ \text { (Non-matl oxide) }}}{ CO _2(g)} \longrightarrow \underset{\substack{\text { Calcium hydroxide } \\ \text { (Salt) }}}{ CaCO _{3(g)}}+\underset{\text { water }}{ H _2 O (l)}$
