Lesson 14 Flashcard

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases energy in the form of heat or light.

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs energy from its surroundings, usually in the form of heat.

Front

Define decomposition reaction.

Back

A decomposition reaction is a type of chemical reaction where a single compound breaks down into two or more simpler substances.

Front

What is a single replacement reaction?

Back

A single replacement reaction is a chemical change in which one element replaces a second element in a compound.

Front

What is a double replacement reaction?

Back

A double replacement reaction is a chemical reaction where two compounds exchange ions or bonds to form two new compounds.

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 heat and light.

Front

What is the general form of a decomposition reaction?

Back

The general form of a decomposition reaction is: AB -> A + B, where AB is a compound that breaks down into its elements.

Front

What is the general form of a single replacement reaction?

Back

The general form of a single replacement reaction is: A + BC -> AC + B, where A replaces B in the compound BC.

Front

What is the general form of a double replacement reaction?

Back

The general form of a double replacement reaction is: AB + CD -> AD + CB, where the ions of two compounds exchange places.

Front

What is the difference between synthesis and decomposition reactions?

Back

Synthesis reactions combine two or more substances to form a new compound, while decomposition reactions break down a compound into simpler substances.
