For the reaction between aqueous calcium nitrate and aqueous sodium hydroxide producing the precipitate (solid) calcium hydroxide and aqueous sodium nitrate (a) write a balanced equation for this reaction
(b) classify the reaction

The given reaction is a substitution reaction in which hydroxil group is exchanged between compounds.

Substitution Reaction:

It is a reaction in which functional group of a compound replaced by the another functional group.

For example-

In the reaction hydroxil group is exchanged between compounds.

1 mole of aqueous calcium nitrate react with  2 moles aqueous sodium hydroxide to produce  1 mole of solid precipitate calcium hydroxide and 2 moles aqueous sodium nitrate.

Therefore, the given reaction is a substitution reaction in which hydroxil group is exchanged between compounds.
