The complete ionic equation for the reaction that occurs when aqueous solutions of lithium sulfide and copper (II) nitrate are mixed is:

2 Li⁺(aq) + S²⁻(aq) + Cu²⁺(aq) + 2 NO₃⁻(aq) ⇒ CuS(s) + 2 Li⁺(aq) + 2 NO₃⁻(aq)

Let's consider the molecular equation for the reaction that takes place when aqueous solutions of lithium sulfide and copper (II) nitrate are mixed. This is a double displacement reaction.

Li₂S(aq) + Cu(NO₃)₂(aq) ⇒ CuS(s) + 2 LiNO₃(aq)

In the complete ionic equation, the aqueous species appear as ions while the solids appear undissociated.

2 Li⁺(aq) + S²⁻(aq) + Cu²⁺(aq) + 2 NO₃⁻(aq) ⇒ CuS(s) + 2 Li⁺(aq) + 2 NO₃⁻(aq)

The complete ionic equation for the reaction that occurs when aqueous solutions of lithium sulfide and copper (II) nitrate are mixed is:

2 Li⁺(aq) + S²⁻(aq) + Cu²⁺(aq) + 2 NO₃⁻(aq) ⇒ CuS(s) + 2 Li⁺(aq) + 2 NO₃⁻(aq)

Answer from: mariamsakayanthebest

2Li⁺(aq) + S²⁻(aq) + Cu²⁺(aq) + 2NO₃⁻(aq) ⟶ 2Li⁺(aq) + 2NO₃⁻(aq) + CuS(s)

Explanation:

An ionic equation uses the symbols (aq) [aqueous] to indicate ions that are soluble in water and (s) [solid] to indicate insoluble solids.

In this equation, aqueous lithium sulfide might react with aqueous copper(II) nitrate to form lithium nitrate and copper(II) sulfide.

1. Possible molecular equation

Li₂S(aq) + Cu(NO₃)₂(aq) ⟶ 2LiNO₃ + CuS

2. Ionic equation

Nitrates and the salts of Group 1 metals are soluble, so LiNO₃ is soluble.

Sulfides are usually insoluble, so CuS is a precipitate.

We write the formulas of soluble salts as ions, and those of insoluble salts in the "molecular" form.

The complete ionic equation is

2Li⁺(aq) + S²⁻(aq) + Cu²⁺(aq) + 2NO₃⁻(aq) ⟶ 2Li⁺(aq) + 2NO₃⁻(aq) + CuS(s)

Determine the wavelength of light emitted when an electron in an li2+ ion makes a transition from an orbital with n = 6 to an orbital with n = 5.

Answer from: Quest

Since there is the same amount of agn03 in both silver chloride and silver nitrate they produce the same amount of moles. therefore silver chloride produces the same amount of silver nitrate, so your answer is 15.0 moles of silver nitrate. i hope this !
