What is the complete ionic equation for the double displacement reaction:

CuNO3(aq) + K2S(aq)=
what is the chemical name and formula of this chemical reaction? plsss. need help

Post your thoughts and I'll be glad to check them.

To determine the complete ionic equation for a double displacement reaction, we first need to identify the ions present in the reactants and products.

The reactants in this reaction are CuNO3(aq) and K2S(aq).

CuNO3 is copper(II) nitrate, which dissociates in water into Cu2+ and NO3- ions.

CuNO3(aq) → Cu2+(aq) + 2NO3-(aq)

K2S is potassium sulfide, which also dissociates in water into K+ and S2- ions.

K2S(aq) → 2K+(aq) + S2-(aq)

The products of the reaction are determined by the swapping of ions. The positive ions from one reactant combine with the negative ions from the other reactant.

Cu2+(aq) + S2-(aq) → CuS(s)

The complete ionic equation for this reaction can be written as follows:

Cu2+(aq) + 2NO3-(aq) + 2K+(aq) + S2-(aq) → CuS(s) + 2K+(aq) + 2NO3-(aq)

In the complete ionic equation, all ions that are aqueous (denoted by (aq)) are written as separate ions, while any solid products are written as their molecular formula.

The chemical name for the reaction is copper(II) nitrate plus potassium sulfide yields copper(II) sulfide plus potassium nitrate.

The chemical formula of the reaction is Cu(NO3)2 + K2S → CuS + 2KNO3.
