How does the number of reactants in a double displacement reaction compare with the number of products

Answer;

Two reactants and two products.

Explanation;A double-replacement reaction occurs when parts of two ionic compounds are exchanged, making two new compounds. A characteristic of a double-replacement equation is that there are two compounds as reactants and two different compounds as products.A precipitate forms in a double-replacement reaction when the cations from one of the reactants combine with the anions from the other reactant to form an insoluble ionic compound.An example of a double displacement reaction is;

CuCl2(aq) + 2 AgNO3(aq) → Cu(NO3)2(aq) + 2 AgCl(s)

A precipitate is formed, that is why the other name of double replacement reaction is precipitation reaction.
