Question

(4) You notice a thin film of insoluble solid floating on the surface of the pool's water. What type of reaction do you think caused this? According to this type of reaction, what would floating film be called? *

Answer 1

A)Double Replacement reaction

B) Precipitate

Step-by-step explanation:

The situation given in question statement refers to double replacement reaction in chemistry.

As the name indicates, it is basically a precipitation reaction in which a precipitate is formed when the cations from one of the reactants react with the anions from the other reactant to produce an ionic product that is not soluble in the solution and it appears on the surface like a thin film of solids

Answer 2

A double-replacement precipitation reaction.

The floating film is called a precipitate.

Step-by-step explanation:

precipitation reaction is a type of double-replacement reaction that occurs when two ionic compounds are dissolved in water and form a new ionic compound that does not dissolve; this new compound falls out of solution as a solid precipitate.
