Double & Single Replacement Test

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.

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 are reactants in a chemical equation?

Back

Reactants are the starting substances in a chemical reaction, found on the left side of the equation.

Front

What are products in a chemical equation?

Back

Products are the substances formed as a result of a chemical reaction, found on the right side of the equation.

Front

What is the activity series of metals?

Back

The activity series of metals is a list that ranks metals by their reactivity, with the most reactive metals at the top.

Front

What is the role of halogens in replacement reactions?

Back

Halogens can participate in replacement reactions, often displacing less reactive halogens from their compounds.

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 general form of a single replacement reaction?

Back

The general form is: A + BC → AC + B, where A replaces B in the compound.

Front

What is a precipitate in a chemical reaction?

Back

A precipitate is a solid that forms and settles out of a liquid mixture during a chemical reaction.

Front

What does it mean if a reaction has no reaction?

Back

It means that no products are formed, often because the reactants do not react under the given conditions.
