Double replacement question

Question

2 AgNO₃ (g) + Ca(OH)2 (g) -› Ca(NO3)2 (g) + 2 AgOH (g)

is this double replacement?

Answer 1

A double replacement reaction will have two compounds as reactants and two compounds as products. Two of the elements will be switching places (metals switch with metals and non-metals switch with non-metals).

Does this reaction have two compounds as reactants and two compounds as products? Yes.

So yes, this is a double replacement reaction.
