Single and Double Replacement Reactions Test Review

Front

What is a single replacement reaction?

Back

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

What are the products of the reaction between iron III bromide and lead metal?

Back

Lead(II) bromide and iron.

Front

What is a coefficient in a chemical equation?

Back

A coefficient is a number placed in front of a formula in a chemical equation to indicate how many molecules or moles of that substance are involved in the reaction.

Front

Back

Single replacement.

Front

What are the products when aqueous barium nitrate reacts with aqueous sodium sulfate?

Back

Barium sulfate and sodium nitrate.

Front

What is the general form of a single replacement reaction?

Back

A + BC → AC + B, where A is an element and BC is a compound.

Front

What is the general form of a double replacement reaction?

Back

AB + CD → AD + CB, where AB and CD are compounds.

Front

What happens to the oxidation states in a single replacement reaction?

Back

The oxidation state of the element that is replaced changes, while the replacing element's oxidation state changes to match that of the replaced element.

Front

What is the significance of balancing chemical equations?

Back

Balancing chemical equations ensures that the law of conservation of mass is followed, meaning the number of atoms of each element is the same on both sides of the equation.
