Chemistry Unit 7 Lesson 5 Practice: Solubility and Dbl Rep. Rcts

Front

What is the reactivity series?

Back

The reactivity series is a list of metals arranged in order of decreasing reactivity. It helps predict how metals will react with other substances, particularly in displacement reactions.

Front

What is a double replacement reaction?

Back

A double replacement reaction is a type of chemical reaction where two compounds exchange ions or bonds to form two new compounds. It typically occurs in aqueous solutions.

Front

What are the products of the reaction between CuCl2(aq) and H2S(aq)?

Back

The products are CuS(s) and HCl(aq).

Front

What ions are produced when Ca3(PO4)2 dissociates in water?

Back

The ions produced are 3Ca^2+ and 2PO4^3-.

Front

What is a combustion reaction?

Back

A combustion reaction is a chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light and heat. It typically produces carbon dioxide and water.

Front

What is the general form of a double replacement reaction?

Back

The general form is AB + CD → AD + CB, where A and C are cations and B and D are anions.

Front

What is the significance of solubility in chemical reactions?

Back

Solubility determines whether a reaction will occur in solution. If a product is insoluble, it may precipitate out of the solution, driving the reaction forward.

Front

What is the role of a precipitate in a double replacement reaction?

Back

A precipitate is a solid that forms from a solution during a chemical reaction. Its formation indicates that a reaction has occurred.

Front

How do you predict the products of a double replacement reaction?

Back

To predict the products, swap the cations and anions of the reactants and check for solubility to determine if a precipitate forms.

Front

What is the formula for lead(II) chloride?

Back

The formula for lead(II) chloride is PbCl2.
