Single and Double Replacement Reactions

Front

What is a single replacement reaction?

Back

A single replacement reaction is a chemical reaction where one element replaces another element in a compound.

Front

What is a double replacement reaction?

Back

A double replacement reaction is a chemical reaction where the anions and cations of two different compounds exchange places, forming two new compounds.

Front

What is the activity series?

Back

The activity series is a list of metals arranged in order of decreasing reactivity. It helps predict whether a reaction will occur.

Front

What are the products of the reaction H2SO4 + BaCl2?

Back

BaSO4(s) + HCl(aq) - Barium sulfate precipitate and hydrochloric acid are formed.

Front

What does it mean if no reaction occurs in a single replacement reaction?

Back

It means that the element attempting to replace another is less reactive than the element in the compound.

Front

What are the products of the reaction CuCl2 + H2S?

Back

CuS(s) + HCl(aq) - Copper sulfide precipitate and hydrochloric acid are formed.

Front

What is the significance of the solubility rules in double replacement reactions?

Back

Solubility rules help predict whether a precipitate will form in a double replacement reaction.

Front

What happens when Br2(l) reacts with KI(aq)?

Back

KBr + I2 - Potassium bromide and iodine are formed.

Front

What is a precipitate?

Back

A precipitate is an insoluble solid that forms when two solutions are mixed.

Front

What is the role of water in chemical reactions?

Back

Water can act as a solvent, reactant, or product in chemical reactions.
