Aqueous solutions of sodium sulfide and copper(II) chloride are mixed together. Which statement is correct? a. Both NaCl and CuS will precipitate from solution b. No precipitate will form c. Only CuS will precipitate from solution d. Only NaCl will precipitate from solution

C.Only CuS will precipitate from solution

Aqueous solutions of sodium sulfide and copper(II) chloride are mixed together.

Na₂S(aq) + CuCl₂(aq) → Products

Na₂S(aq) + CuCl₂(aq) →  CuS(s) ↓ +  2NaCl(aq)

When the sulfide bond to the cation Cu²⁺ it makes a precipitate (s)

Thus,the correct answer is C.

The correct state for the answer is c.

Only CuS will precipitate from solution

Explanation:

We analyse the compounds for the reaction and we write the equation:

Na₂S(aq) + CuCl₂(aq) → Products

For this case, the products are NaCl and CuS. The complete balanced reaction is:

Na₂S(aq) + CuCl₂(aq) →  CuS(s) ↓ +  2NaCl(aq)

When the sulfide bond to the cation Cu²⁺ it makes a precipitate (s)

Salts from chlorides are soluble except for the Ag⁺, Pb⁺ or Cu⁺

Salts from S⁻² which are soluble, are found in the group 2 of the Periodic Table (Ca²⁺, Ba²⁺, Mg²⁺)

The correct state for the answer is c.

it is called acid bonding

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
